  • "Collection Wrapper" pattern - is this common?

    - by Prog
    A different question of mine had to do with encapsulating member data structures inside classes. In order to understand this question better please read that question and look at the approach discussed. One of the guys who answered that question said that the approach is good, but if I understood him correctly - he said that there should be a class existing just for the purpose of wrapping the collection, instead of an ordinary class offering a number of public methods just to access the member collection. For example, instead of this: class SomeClass{ // downright exposing the concrete collection. Things[] someCollection; // other stuff omitted Thing[] getCollection(){return someCollection;} } Or this: class SomeClass{ // encapsulating the collection, but inflating the class' public interface. Thing[] someCollection; // class functionality omitted. public Thing getThing(int index){ return someCollection[index]; } public int getSize(){ return someCollection.length; } public void setThing(int index, Thing thing){ someCollection[index] = thing; } public void removeThing(int index){ someCollection[index] = null; } } We'll have this: // encapsulating the collection - in a different class, dedicated to this. class SomeClass{ CollectionWrapper someCollection; CollectionWrapper getCollection(){return someCollection;} } class CollectionWrapper{ Thing[] someCollection; public Thing getThing(int index){ return someCollection[index]; } public int getSize(){ return someCollection.length; } public void setThing(int index, Thing thing){ someCollection[index] = thing; } public void removeThing(int index){ someCollection[index] = null; } } This way, the inner data structure in SomeClass can change without affecting client code, and without forcing SomeClass to offer a lot of public methods just to access the inner collection. CollectionWrapper does this instead. E.g. if the collection changes from an array to a List, the internal implementation of CollectionWrapper changes, but client code stays the same. Also, the CollectionWrapper can hide certain things from the client code - from example, it can disallow mutation to the collection by not having the methods setThing and removeThing. This approach to decoupling client code from the concrete data structure seems IMHO pretty good. Is this approach common? What are it's downfalls? Is this used in practice?

  • OOP PHP make separate classes or one

    - by user2956219
    I'm studying OOP PHP and working on a small personal project but I have hard time grasping some concepts. Let's say I have a list of items, each item belongs to subcategory, and each subcategory belongs to category. So should I make separate classes for category (with methods to list all categories, add new category, delete category), class for subcategories and class for items? Or should I make creating, listing and deleting categories as methods for item class? Both category and subcategory are very simple and basically consist of ID, Name and parentID (for subcategory).

  • What is the better design decision approach?

    - by palm snow
    I have two classes (MyFoo1 and MyFoo2) that share some common functionality. So far it does not seem like I need any polymorphic inheritence but at this point I am considering the following options: Have the common functionality in a utility class. Both of these classes call these methods from that utility class. Have an abstract class and implement common methods in that abstract class. Then derive MyFoo1 and MyFoo2 from that abstract class. Any suggestion on what would be a better design decision?

  • If you need more than 3 levels of indentation, you're screwed?

    - by jokoon
    Per the Linux kernel coding style document: The answer to that is that if you need more than 3 levels of indentation, you're screwed anyway, and should fix your program. What can I deduce from this quote? On top of the fact that too long methods are hard to maintain, are they hard or impossible to optimize for the compiler? I don't really understand if this quote encourages better coding practice or is really a mathematical / algorithmic sort of truth. I also read in some C++ optimizing guide that "dividing up a program into more functions improves its design" is frequently taught in CS courses, but it should be not done too much, since it can turn into a lot of JMP calls (even if the compiler can inline some methods by itself).

  • What Does Google Social Search Mean For Website Optimisation?

    Google's latest output, Social Search, allows users to search for information via their personal connections on Twitter and other networking sites. With social search rapidly growing in popularity, the idea is basically to get the input of a user's friends, rather than anonymous websites. Social search results are incorporated right into those of a normal search engine results page (SERP) similar to how images, videos and other content are currently integrated into regular listings.

  • iPhone SDK / Objective C Syntax Question

    - by Koppo
    To all, I was looking at the sample project from http://iphoneonrails.com/ and I saw they took the NSObject class and added methods to it for the SOAP calls. Their sample project can be downloaded from here http://iphoneonrails.com/downloads/objective_resource-1.01.zip. My question is related to my lack of knowledge on the following syntax as I haven't seen it yet in a iPhone project. There is a header file called NSObject+ObjectiveResource.h where they declare and change NSObject to have extra methods for this project. Is the "+ObjectiveResource.h" in the name there a special syntax or is that just the naming convention of the developers. Finally inside the class NSObject we have the following #import <Foundation/Foundation.h> @interface NSObject (ObjectiveResource) // Response Formats typedef enum { XmlResponse = 0, JSONResponse, } ORSResponseFormat; // Resource configuration + (NSString *)getRemoteSite; + (void)setRemoteSite:(NSString*)siteURL; + (NSString *)getRemoteUser; + (void)setRemoteUser:(NSString *)user; + (NSString *)getRemotePassword; + (void)setRemotePassword:(NSString *)password; + (SEL)getRemoteParseDataMethod; + (void)setRemoteParseDataMethod:(SEL)parseMethod; + (SEL) getRemoteSerializeMethod; + (void) setRemoteSerializeMethod:(SEL)serializeMethod; + (NSString *)getRemoteProtocolExtension; + (void)setRemoteProtocolExtension:(NSString *)protocolExtension; + (void)setRemoteResponseType:(ORSResponseFormat) format; + (ORSResponseFormat)getRemoteResponseType; // Finders + (NSArray *)findAllRemote; + (NSArray *)findAllRemoteWithResponse:(NSError **)aError; + (id)findRemote:(NSString *)elementId; + (id)findRemote:(NSString *)elementId withResponse:(NSError **)aError; // URL construction accessors + (NSString *)getRemoteElementName; + (NSString *)getRemoteCollectionName; + (NSString *)getRemoteElementPath:(NSString *)elementId; + (NSString *)getRemoteCollectionPath; + (NSString *)getRemoteCollectionPathWithParameters:(NSDictionary *)parameters; + (NSString *)populateRemotePath:(NSString *)path withParameters:(NSDictionary *)parameters; // Instance-specific methods - (id)getRemoteId; - (void)setRemoteId:(id)orsId; - (NSString *)getRemoteClassIdName; - (BOOL)createRemote; - (BOOL)createRemoteWithResponse:(NSError **)aError; - (BOOL)createRemoteWithParameters:(NSDictionary *)parameters; - (BOOL)createRemoteWithParameters:(NSDictionary *)parameters andResponse:(NSError **)aError; - (BOOL)destroyRemote; - (BOOL)destroyRemoteWithResponse:(NSError **)aError; - (BOOL)updateRemote; - (BOOL)updateRemoteWithResponse:(NSError **)aError; - (BOOL)saveRemote; - (BOOL)saveRemoteWithResponse:(NSError **)aError; - (BOOL)createRemoteAtPath:(NSString *)path withResponse:(NSError **)aError; - (BOOL)updateRemoteAtPath:(NSString *)path withResponse:(NSError **)aError; - (BOOL)destroyRemoteAtPath:(NSString *)path withResponse:(NSError **)aError; // Instance helpers for getting at commonly used class-level values - (NSString *)getRemoteCollectionPath; - (NSString *)convertToRemoteExpectedType; //Equality test for remote enabled objects based on class name and remote id - (BOOL)isEqualToRemote:(id)anObject; - (NSUInteger)hashForRemote; @end What is the "ObjectiveResource" in the () mean for NSObject? What is that telling Xcode and the compiler about what is happening..? After that things look normal to me as they have various static and instance methods. I know that by doing this all user classes that inherit from NSObject now have all the extra methods for this project. My question is what is the parenthesis are doing after the NSObject. Is that referencing a header file, or is that letting the compiler know that this class is being over ridden. Thanks again and my apologies ahead of time if this is a dumb question but just trying to learn what I lack.

  • Dual AJAX Requests at different times

    - by Nik
    Alright, I'm trying to make an AJAX Chat system that polls the chat database every 400ms. That part is working, the part of which isn't is the Active User List. When I try to combine the two requests, the first two requests are made, then the whole thing snowballs and the usually timed (12 second) Active User List request starts updating every 1ms and the first request NEVER happens again. Displayed is the entire AJAX code for both requests: var waittime=400;chatmsg=document.getElementById("chatmsg"); room = document.getElementById("roomid").value; chatmsg.focus() document.getElementById("chatwindow").innerHTML = "loading..."; document.getElementById("userwindow").innerHTML = "Loading User List..."; var xmlhttp = false; var xmlhttp2 = false; var xmlhttp3 = false; function ajax_read(url) { if(window.XMLHttpRequest){ xmlhttp=new XMLHttpRequest(); if(xmlhttp.overrideMimeType){ xmlhttp.overrideMimeType('text/xml'); } } else if(window.ActiveXObject){ try{ xmlhttp=new ActiveXObject("Msxml2.XMLHTTP"); } catch(e) { try{ xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } catch(e){ } } } if(!xmlhttp) { alert('Giving up :( Cannot create an XMLHTTP instance'); return false; } xmlhttp.onreadystatechange = function() { if (xmlhttp.readyState==4) { document.getElementById("chatwindow").innerHTML = xmlhttp.responseText; setTimeout("ajax_read('methods.php?method=r&room=" + room +"')", waittime); } } xmlhttp.open('GET',url,true); xmlhttp.send(null); } function user_read(url) { if(window.XMLHttpRequest){ xmlhttp3=new XMLHttpRequest(); if(xmlhttp3.overrideMimeType){ xmlhttp3.overrideMimeType('text/xml'); } } else if(window.ActiveXObject){ try{ xmlhttp3=new ActiveXObject("Msxml2.XMLHTTP"); } catch(e) { try{ xmlhttp3=new ActiveXObject("Microsoft.XMLHTTP"); } catch(e){ } } } if(!xmlhttp3) { alert('Giving up :( Cannot create an XMLHTTP instance'); return false; } xmlhttp3.onreadystatechange = function() { if (xmlhttp3.readyState==4) { document.getElementById("userwindow").innerHTML = xmlhttp3.responseText; setTimeout("ajax_read('methods.php?method=u&room=" + room +"')", 12000); } } xmlhttp3.open('GET',url,true); xmlhttp3.send(null); } function ajax_write(url){ if(window.XMLHttpRequest){ xmlhttp2=new XMLHttpRequest(); if(xmlhttp2.overrideMimeType){ xmlhttp2.overrideMimeType('text/xml'); } } else if(window.ActiveXObject){ try{ xmlhttp2=new ActiveXObject("Msxml2.XMLHTTP"); } catch(e) { try{ xmlhttp2=new ActiveXObject("Microsoft.XMLHTTP"); } catch(e){ } } } if(!xmlhttp2) { alert('Giving up :( Cannot create an XMLHTTP instance'); return false; } xmlhttp2.open('GET',url,true); xmlhttp2.send(null); } function submit_msg(){ nick = document.getElementById("chatnick").value; msg = document.getElementById("chatmsg").value; document.getElementById("chatmsg").value = ""; ajax_write("methods.php?method=w&m=" + msg + "&n=" + nick + "&room=" + room + ""); } function keyup(arg1) { if (arg1 == 13) submit_msg(); } var intUpdate = setTimeout("ajax_read('methods.php')", waittime); var intUpdate = setTimeout("user_read('methods.php')", waittime);

  • Using a GoDaddy SSL certificate with Virtualmin (Webmin)

  • How to use cURL to FTPS upload to SecureTransport (hint: SITE AUTH and client certificates)

    - by Seamus Abshere
    I'm trying to connect to SecureTransport 4.5.1 via FTPS using curl compiled with gnutls. You need to use --ftp-alternative-to-user "SITE AUTH" per http://curl.haxx.se/mail/lib-2006-07/0068.html Do you see anything wrong with my client certificates? I try with # mycert.crt -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE----- # mykey.pem -----BEGIN RSA PRIVATE KEY----- ... -----END RSA PRIVATE KEY----- And it says "530 No client certificate presented": myuser@myserver ~ $ curl -v --ftp-ssl --cert mycert.crt --key mykey.pem --ftp-alternative-to-user "SITE AUTH" -T helloworld.txt ftp://ftp.example.com:9876/upload/ * About to connect() to ftp.example.com port 9876 (#0) * Trying 1.2.3.4... connected * Connected to ftp.example.com (1.2.3.4) port 9876 (#0) < 220 msn1 FTP server (SecureTransport 4.5.1) ready. > AUTH SSL < 334 SSLv23/TLSv1 * found 142 certificates in /etc/ssl/certs/ca-certificates.crt > USER anonymous < 331 Password required for anonymous. > PASS [email protected] < 530 Login incorrect. > SITE AUTH < 530 No client certificate presented. * Access denied: 530 * Closing connection #0 curl: (67) Access denied: 530 I also tried with a pk8 version... # openssl pkcs8 -in mykey.pem -topk8 -nocrypt > mykey.pk8 -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE----- ...but got exactly the same result.

  • Configure ApacheDS 1.5 with accessControlEnabled=true for authenticated access

    - by cmyers
    I need to set up an apacheDS instance. I am using standalone 1.5.5 on Linux. I have removed the example partition and added two of my own, each with their own suffixes. I have imported LDIFs for the two partitions and everything looks correct data-wise. I need to configure ApacheDS to disallow anonymous access. I was able to do that by following some of the directions here: http://directory.apache.org/apacheds/1.5/145-enable-and-disable-anonymous-access.html http://directory.apache.org/apacheds/1.5/32-basic-authorization.html Now only the administrator account (uid=admin,ou=system) can log in and make queries. I need to establish an admin account, and a "regular user" account which can read and write only certain entries within each partition. I tried to read the above docs and I got nuthin'. The second page "basic authorization" is completely incomprehensible to me. When I tried to add a "prescriptiveACI" to it using Apache Directory Studio, I get: Administration point 2.5.4.11=abc,2.5.4.10=efg does not contain an administrativeRole attribute! An administrativeRole attribute in the administrative point is required to add a subordinate subentry. where my partition is "ou=abc,o=def". I have no clue what is going on and the docs are really not helping, I am at a complete loss here. How can it possibly be this hard to just restrict access? P.S. can someone with proper rep please change the tag "apache" to the new tag "ApacheDS"?

  • Authentication required by wireless network.

    - by Roman
    I would like to use a wireless network from Ubuntu. In the network drop-down menu I select a network (this is a University network I have an account there). Then I get a windows with the following fields: Wireless Security: [WPA&WPA2 Enterprise] Authentication: [Tunneled TLS] Anonymous Identity: [] CA Certificate: [(None)] Inner Authentication: [some letters] User Name: [] Password: [] I put there my user name and password and do not change default value and leave "Anonymous Identity"blank. As a result of that I get "Authentication required by wireless network". How can I solve this problem? I think it is important to notice that our system administrator tried to find some files (which are probably needed to be used as "CA Certificate"). He said that he does not know where this file is located on Ubuntu (he support only Windows). So, probably this is direction I need to go. I need to find this file. But may be I am wrong. May be something else needs to be done. Could you pleas help me with that?

  • Biztalk 2009 logshipping with SQL 2008

  • Exchange 2010 Mail Enabled Public Folder Unable to Recieve External (anon) e-mail.

    - by Alex
    Hello All, I am having issues with my "Public Folders" mail enabled folders receiving e-mails from external senders. The folder is setup with three Accepted Domains (names changed for privacy reasons): 1 - domain1.com (primary & Authoritative) 2 - domain2.com (Authoritative) 3 - domain3.com (Authoritative) When someone attempts to send an e-mail to [email protected] from inside the organization, the e-mail is received and placed in the appropriate folder. However, when someone tries to send an e-mail from outside the organization (such as a gmail account), the following error message is received: "Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 554 554 Recipient address rejected: User unknown (state 14)." When I try to send an e-mail to the same folder, using the same e-mail address above ([email protected]), but with domain2.com instead of domain3.com, it works as intended (both internal & external). I have checked, double checked, and triple checked my DNS settings comparing those from domain2 & domain3 with them both appearing identical. I have tried recreating the folders in question with the same results. I have also ran Get-PublicFolderClientPermission "\Web Programs\folder" with the following results for user anonymous: RunspaceId : 5ff99653-a8c3-4619-8eeb-abc723dc908b Identity : \Web Programs\folder User : Anonymous AccessRights : {CreateItems} Domain2.com & Domain3.com are duplicates of each other, but only domain2.com works as intended. All other exchange functions are functioning properly. If anyone out there has any suggestions, I would love to hear them. I've just hit a brick wall. Thanks for all your help in advance! --Alex

  • How can I enable PHP5 for a site? Having problems with every single method.

    - by John Stephens
    I'm working on a client site that is hosted on someone's DIY Debian Linux server [Apache/1.3.33 (Debian GNU/Linux)], and I'm trying to install a script that requires PHP5. By default, the server parses .php files with PHP 4.3.10-22, which is configured at /etc/php4/apache/php.ini, according to phpinfo(). On the server I can see a config directory for PHP5 adjacent to the PHP4 directory: /etc/php5.0/apache2/php.ini. I have tried multiple methods to enable PHP5 for the document root where the site's files are hosted, including all available methods mentioned here. By far, the most common suggestion I've found is to add one or both of the following lines to the site's .htaccess file: AddHandler application/x-httpd-php5 .php AddType application/x-httpd-php5 .php Trouble is, when either or both of those lines are present, the site forces my browser to download any .php files requested, without parsing the PHP at all. All of the other methods mentioned in the above article cause a 500 Internal Server Error. There is no hosting control panel I can access in a browser to enable PHP5 for the site, but I do have shell access. When I asked the server administrator about this issue, he encouraged me to search for the answer on Google. Where could I begin to troubleshoot this issue? Are there ways to test or verify the server's specific PHP5 installation and configuration, using the command line or some other method? Do you have other suggestions to enable PHP5?

  • FastCGI Error when installing PHP on IIS7.5

    - by ytoledano
    I'm trying to install MediaWiki on a Win2008r2 server, but can't manage to install PHP. Here's what I did: Grabbed a Zip archive of PHP and unzipped it into C:\PHP. Created two subdirs: c:\PHP\sessiondata and c:\PHP\uploadtemp. Granted modify rights to the IUSR account for the subdirs. Copied php.ini-production as php.ini Edited php.ini and made the following changes: fastcgi.impersonate = 1 cgi.fix_pathinfo = 1 cgi.force_redirect = 0 open_basedir = "c:\inetpub\wwwroot;c:\PHP\uploadtemp;C:\PHP\sessiondata" extension = php_mysql.dll extension_dir = "./ext" upload_tmp_dir = C:\PHP\uploadtemp session.save_path = C:\php\sessiondata Install Web server role, selected CGI and HTTP Redirection options. In the Handler Mappings: Added Module Mapping. Entered the following values: Path = *.php, Module = FastCgiModule, Executable = c:\php\php-cgi.exe, Name = PHP via FastCGI. Created a test page into wwwroot directory: phpinfo.php and set the contents like this: < ?php phpinfo(); ? Browsed to http://localhost/phpinfo.php But then I get: HTTP Error 500.0 - Internal Server Error An unknown FastCGI error occured Detailed Error Information Module: FastCgiModule Notification: ExecuteRequestHandler Handler: PHP via FastCGI Error Code: 0x800736b1 Requested URL: http://localhost:80/phpinfo.php Physical Path: C:\inetpub\wwwroot\phpinfo.php Logon Method: Anonymous Logon User: Anonymous Does anyone know what I'm doing wrong here?

  • Exchange Connector Won't Send to External Domains

    - by sisdog
    I'm a developer trying to get my .Net application to send emails out through our Exchange server. I'm not an Exchange expert so I'll qualify that up front!! We've set up a receive Connector in Exchange that has the following properties: Network: allows all IP addresses via port 25. Authentication: Transport Layer Security and Externally Secured checkboxes are checked. Permission Groups: Anonymous Users and Exchange Servers checkboxes are checked. But, when I run this Powershell statement right on our Exchange server it works when I send to a local domain address but when I try to send to a remote domain it fails. WORKS: C:\Windows\system32Send-Mailmessage -To [email protected] -From [email protected] -Subject testing -Body testing -SmtpServer OURSERVER (BTW: my value for OURSERVER=boxname.domainname.local. This is the same fully-qualified name that shows up in our Exchange Management Shell when I launch it). FAILS: C:\Windows\system32Send-Mailmessage -To [email protected] -From [email protected] -Subject testing -Body testing -SmtpServer OURSERVER Send-MailMessage : Mailbox unavailable. The server response was: 5.7.1 Unable to relay At line:1 char:17 + Send-Mailmessage <<<< -To [email protected] -From [email protected] -Subject testing -Body himom -SmtpServer FTI-EX + CategoryInfo : InvalidOperation: (System.Net.Mail.SmtpClient:SmtpClient) [Send-MailMessage], SmtpFailed RecipientException + FullyQualifiedErrorId : SmtpException,Microsoft.PowerShell.Commands.SendMailMessage EDIT: From @TheCleaner 's advice, I ran the Add-ADPermission to the relay and it didn't help; [PS] C:\Windows\system32Get-ReceiveConnector "Allowed Relay" | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -E xtendedRights "Ms-Exch-SMTP-Accept-Any-Recipient" Identity User Deny Inherited -------- ---- ---- --------- FTI-EX\Allowed Relay NT AUTHORITY\ANON... False False Thanks for the help. Mark

  • 530 5.7.1 Client was not authenticated Exchange 2010 for some computers within mask

    - by user1636309
    We have a classic problem with Client not Authenticated but with a specific twist: We have an Exchange 2010 cluster, let's say EX01 and EX02, the connection is always to smtp.acme.com, then it is switched through load balancer. We have an application server, call it APP01 There are clients connected to the APP01. There is a need for anonymous mail relay from both clients and APP01. The Anonymous Users setting of the Exchange is DISABLED, but the specific computers - APP01 and clients by the mask, let's say, 192.168.2.* - are enabled. For internal relay, a "Send Connector" is created, and then the above IP addresses are added for the connector to allow computers, servers, or any other device such as a copy machine to use the exchange server to relay email to recipients. The problem is that the relay works for APP01 and some clients, but not others (we get "Client not Authenticated") - all inside the same network and the same mask. This is basically what we do to test it outside of our application: http://smtp25.blogspot.sk/2009/04/530-571-client-was-not-authenticated.html So, I am looking for ideas: What can be the reason for such a strange behaviour? Where I can see the trace of what's going on at the Exchange side?

  • QMail do not delivery to remote mailboxes for my own domain

    - by lorenzo-s
    Sorry for the title, I don't know how to sum up this situation. I have a web server at mydomain.com, running qmail for website related mail delivery (i.e. newsletter, sign up confirmation, etc). qmail here is used only to send mails, because I have a fully working Google App Gmail associated with mydomain.com for normal email receiving. qmail runs fine when sending email to remote addresses, for example to [email protected], but fails when sending to [email protected]. I think it's because the server thinks that he have to manage mailboxes for mydomain.com locally, instead of redirect them to Gmail. Here is the /var/log/qmail/current for two email: the first one is sent without problems to example.com, second one fails because it's for mydomain.com: 2012-11-15 15:04:11.551933500 new msg 262580 2012-11-15 15:04:11.551936500 info msg 262580: bytes 5604 from <[email protected]> qp 5185 uid 33 2012-11-15 15:04:11.575910500 starting delivery 316: msg 262580 to remote [email protected] 2012-11-15 15:04:11.575912500 status: local 0/10 remote 1/20 2012-11-15 15:04:12.189828500 delivery 316: success: 74.125.136.27_accepted_message./Remote_host_said:_250_2.0.0_OK_1352991894_j49si13055539eep.9/ 2012-11-15 15:04:12.189830500 status: local 0/10 remote 0/20 2012-11-15 15:04:12.189831500 end msg 262580 2012-11-15 16:49:20.270332500 new msg 262580 2012-11-15 16:49:20.270336500 info msg 262580: bytes 2192 from <[email protected]> qp 5479 uid 33 2012-11-15 16:49:20.315125500 starting delivery 323: msg 262580 to local [email protected] 2012-11-15 16:49:20.315128500 status: local 1/10 remote 0/20 2012-11-15 16:49:20.320855500 delivery 323: failure: Sorry,_no_mailbox_here_by_that_name._(#5.1.1)/ 2012-11-15 16:49:20.320858500 status: local 0/10 remote 0/20 2012-11-15 16:49:20.372911500 bounce msg 262580 qp 5484 2012-11-15 16:49:20.372914500 end msg 262580 As you can see, it says: Sorry,_no_mailbox_here_by_that_name I can't say he's wrong :) How to solve this? How to let Google App Gmail manage incoming email for mydomain.com for messages sent by mydomain.com qmail server?
