  • What ports to open for mail server?

    - by radman
    Hi, I have just finished setting up a Postfix mail server on a linux (ubuntu) platform. I have it sending and receiving email and it is not an open relay. It also supports secure smtp and imap. Now this is a pretty beginner question but should I be leaving port 25 open? (since secure smtp is preferred). if so then why? Also what about port 587? Also should I require any authentication on either of these ports? Please excuse my ignorance in this area :P

  • "IP May Be Forged" - Sendmail Warning

    - by Mikey B
    CentOS 5.x | SendMail 8 Can I get clarification on what exactly the warning "IP may be forged" means and what conditions cause it? I recently configured SendMail to relay email from my exchange server and it's showing that warning in the logs. The messages get delivered fine but I don't like the warnings. I originally thought that there was an inconsistency between the servername used in the EHLO statement from Exchange and the respective PTR record for the source IP for Exchange. But upon examining a packet capture, I see exchange using "EHLO domain.com" and that the source IP has a PTR of "domain.com". Maybe sendmail doesn't like that the greeting only has the domain? -M

  • 450 Error with Postfix

    - by Shiv
    I have setup postfix to send outgoing mail, It works fine for most of the cases except for some e.g duke.alumni.edu where it gives me a 450 error, even though the email address is valid. This is the exact error I get Sender address rejected: Domain not found (in reply to RCPT TO command)) Any suggestions on how I can rectify this?

  • Handling emails on a web server - Making sure the FQDN is set correctly based on the website sending the email

    - by webnoob
    I have a Windows 2008 Web Edition server hosting multiple websites using IIS 7.5. At the moment, all the emails are sent via the IIS6 SMTP service. The FQDN of the SMTP service is set to the computer name at the moment which isn't correct as it doesn't resolve to a valid DNS entry and is not RFC compliant. Some questions: Is there any way I can change the FQDN of the SMTP service based on the site sending the email? Would it be Ok to just setup mailserver.mydomain.com and use that as the FQDN for all the sites on multiple domains. Should I be using some other mail server software to handle this better? The reason I am asking is lots of emails are hitting spam folders because the settings are incorrect. I have access to the code that is running the websites so if something needs to be done there then that shouldn't be a problem. The sites are written using ASP.NET 2.0. EDIT: I have just found an option to create an SMTP virtual service. Would this be the way forward? Create a virtual server for each site? Thanks.

  • How to manage unprivileged administration of system services using Debian?

    - by ypnos
    At our lab, we have several services handled by different phd students (like myself). Fluctuation is high and people do the job next to their research duties. Until now, services were running on different machines, with different OS setups that can result in administration hell quickly. We want to consolidate our service setup. Our main idea is that the guys responsible for the services should not meddle with the underlying system anymore. Apart from core systems like NFS and kerberos, a typical service is able to run as non-root already. I'm talking about apache, mysql, subversion, mail with openxchange, and so on. Redirecting privileged ports is also no issue (source). What is left is the configuration of the service and its payload. One scenario we envisioned is that every service has its own user and home directory, accessable by the corresponding admins. Backup and fallback of the service is easy, as everything needed for the service to run is found in one place. Are there established ways to create such a setup? Does a mostly unique method exist to make services find their files (other than in system directories) while still using the corresponding debian packages? Are there any catches with our idea that we may have overlooked? Would you maybe claim that virtualization is the answer to our problem? (In our POV, it wouldn't help us keeping system setup strictly separated from service setup.) Thank you for any advice!

  • email archive for multiple users

    - by evanmcd
    Hi, I'm moving a web site from one server to another, and am realizing that I need to move the name servers for the domain as well (they are set to the current host, not to the registrar). So, knowing that email services will stop as soon as I switch the DNS, I'm scrambling to figure out how to archive and make available email data for folks that have mostly been using webmail for the past few years, and may not even have a computer on which to install a client to download the mail to. What does one do in this situation? Thanks for any help offered! Evan

  • Windows 2003 - Isolate mailserver on webserver with VMware Server

    - by user43279
    Hi, I've a Virtual Private Server with Windows 2003 and root access. This server mainly acts as a web hosting machine (IIS, Apache). Additionally it is used as a mail server. Is it possible to isolate a mailserver (for example HMailServer) by using VMware Server on Windows 2003 in order to avoid potential viruses moving from the guest into the host system? Is this is a good direction to protect the web server from viruses? Kind regards, Jakub

  • Sending eMails in a external subnet in vmware ESXi

    - by user80658
    This might be a bit hard for me to explain - and it is a pretty individual situation. I got a native server at Hetzner (www.hetzner.de). The public IP is 88.[...].12. I got ESXi running on this server. I can access the esxi console by the public ip, but none of the virtual machines. That's why I bought a public subnet with 8 (6 usable) IPs (46.[...]) and an additional public ip (88.[...].26). This additional public ip belongs to the first virtual maschine - a firewall appliance - which is connected to the WAN. This need to be done this way - since it is the official way by hetzner. My 46. subnet is behind the firewall. I got a virtualmin server with dovecot imap/pop3 server. When sending a email, most provider (gmail) will accept those mails, but a lot will put it into spam (aol). My theory is: The MX line of my domain says of course the ip of the virtual machine (46.[...]), but in the raw email it says that email is sent by the ip of the firewall (88.[...].26), which doesnt sound trustworthy. A solution would be if the firewall could handle mail, but it simply cant. How can I prevent this problem? Thanks.

  • MDaemon vs Exchange (2007-2010). Which way should we choose ?

    - by Deniz
    We are at the verge of a mail server decision. We do currently use 2 mail servers : MDaemon 10 and Exchange 2003. We are planning to use a company and customer wide one point solution. Our main candidates are MDaemon 11 and Exchange 2007 or 2010. We would like to learn other users experiences on those solutions. The server-side experiences, the user-side experiences , TCO, support options etc. And if there where other solutions (maybe MDaemon 11 + Exchange or anything else) you could suggest ?

  • Which steps are required to avoid my server being considered as spam sender?

    - by Cyril N.
    I'm looking to set up a webmail server that will be used by a lots of users that will receive and send emails. They will also have the possibility to forward emails they receive. I'd like to know which steps are recommanded/required to indicate to others Mail services (GMail, Outlook, etc) that my server is not used as a spam sender (disclaimer : IT's NOT ! :p) but a legitimate one. I know I have to define a SPF TXT records for example, but what others steps would you recommend me to do ? For example, is there a formula like having a proportional number of servers based on the amount of email sent (for having a different IP address) ? (something like sending a maximum of 1M emails / per IP / per day ?) Something else I'm missing ? I tried to search online, but I mostly find how to avoid emails sent with scripts (like PHP) being put in the SPAM folder. I'm looking for a server/dns configuration side. Thanks a lot for your help/tips, I appreciate !

  • How to whitelist a domain while blocking forgeries using that domain?

    - by QuantumMechanic
    How do you deal with the case of: wanting to whitelist a domain so that emails from it won't get eaten, but not having emails forged to appear to be from that domain get bogusly whitelisted whitelist_from_recvd looks promising, but then you have to know at least the TLD of every host that could send you mail from that domain. Often RandomBigCompany.com will outsource email to one or more sending companies (like Constant Contact and the like) in addition to using servers that reverse-resolve to something in its own domain. But it looks like whitelist_from_recvd can only map to one sending server pattern so that would be problematic. Is there a way to say something like "if email is from domain X, subtract N points from the spam score"? The idea would be that if the mail is legit, that -N will all but guarantee it isn't considered spam. But if it is spam, hopefully all the other failed tests will render it spam even with the -N being included.

  • Setting up and moving a distribution group to a public folder in Exchange 2003

    - by Sevdarkseed
    I'm looking for some advice with something that seems simple but I haven't done before. Currently we use a distribution group called Orders that has an email address that is that forwarded to four people in the company, the same goes for another one, Quotes. The problem is, of course, no one knows what was answered, and all the email gets worked in to the individual user's emails, so I'm thinking that a public folder, only accessible by one department would be the answer. I'm not sure what the best way to set this up would be or how to move/convert the current distribution list over to a public folder. This is a very critical email address in the company, so I'm trying to be sure that there is zero down time at all for it. What would be the best way to go about creating a public folder and converting/forwarding/moving/(whatever) over the current email address to that folder?

  • Postfix auto create Maildir

    - by Eugene
    I've been beating my head against a wall for a while now on this one. Basically, here is the rundown: Our MX record points to a frontend SMTP server, which contains aliases for actually routing the mail. No alias, no access to the backend storage server, which is what our clients connect to. I'm upgrading the backend email server. Currently, a user is created for every email user on the server, which creates the mailbox. On the new server, everything autheticates through PAM to an LDAP server (all of which is working properly). My goal is to get Postfix to create the Maildir directory for the user automatically. This works fine when I have the /home directory with 777 permissions, but for obvious reasons, this should be avoided. I would like to do this with 775 permissions on /home with a group owner of whatever user Postfix is running as, but I can't seem to figure out what user to use. With the 777 permissions, the /home/$user/Maildir directory is created on message delivery. Does anybody know how I can do this without 777 permissions? The system I am working on is a 64-bit Debian Lenny 5.07 install. Any advice would be appreciated.

  • Mail server for Windows 2008

    - by waldev
    I'm going to get a Windows 2008 dedicated server sometime soon. I'm going to have my website hosted on it, so, I also want to run a mail server on the same machine to receive any mail sent to the website (I use the SMTP Server in IIS for sending mail, but this about receiving not sending) Does Windows 2008 have a built-in POP3 OR IMAP server? If so, can it be accessed through a webmail interface? I mean does it also have a webmail interface similar to OWA for example? If not, do you have suggestions for a good mail server with a webmail interface, preferably free or open source? MS Exchange is above my budget and my needs are so simple anyway. I heard good things about hMailServer but I checked and it doesn't have a webmail interface. I know I can outsource this to a third party for a little monthly fee, but I prefer to host my own server. Thanks for any suggestions

  • If I let Google handle my emails for my domain, my Wordpress site won't send out emails anymore

    - by Fulvio
    Since I decided to let Google handle all my emails for my domain, while the domain is hosted on a 3rd party server, emails send out by a Wordpress installation no longer work. My supposition is that since all email is being routed to Google, my specific account on that server for that domain is unable to send out emails. I definitely wish to keep using google services for handling my emails since it comes with all the advantages connected to a Google account. However I need my Wordpress installation to send out administrative emails. I run my server with CPanel. How to configure that specific account and/or Wordpress to keep it able to send out emails? I don't need people to answer these emails sent out from server (eventually I might set a reply-to-address perhaps) thanks

  • Mail sending program & exchange server

    - by Emre
    Hi, I have been asked to send about 6500 e-mails to addresses in a member database. I have written the program, that sends and reports the ones that couldn't send etc. But my concern is that this program will just call smtpclient.Send(); and I don't know what happens if 6000 mails are in the queue. Server is MS Exchange as I have been told. Note: I am planning to send them, say 500 by 500. But what if an exception occurs on the Exchange server at 120... then what happens to the other ones.. I will appreciate little insight to the subject. Thanks in advance.

  • Cloud service to receive up to 30000 emails a minute

    - by David
    I am building a business where I want the infrastructure to be able to handle up to 30000 emails per minute during peak periods. The question is what kinds of services offer this? I expect to download the emails using SMTP or similar. I expect each email to have a total attachment size of 2 mb, and might have several attachments. I have considered utilizing Parse API from SendGrid, but I am worried because they offer this service for free. I have contacted them and I am waiting for answer. Are there any better and more suitable alternatives?

  • Postfix sending mail back to itself? (Ubuntu 9.10)

    - by webo
    I setup Dovecot and Postfix using the "Dovecot-Postfix" package with SASL and all that. The Dovecot part seems to be working fine but I'm having issues with Postfix. Whenever I send a message to another address through the postfix server, two things happen. the message never gets to the other address (even when I request a delivery notification, it says that it's been delivered but it's not in the spam box in the other inbox or anything) The message comes back to my inbox through Dovecot as though I sent it to myself internally. e.g. I send an email through my postfix server to my gmail account, 10 minutes later nothing shows up in my gmail account but the message comes back to me as though I was sending it to my internal address (with no errors) Any ideas?

  • How To Send Email to Active Directory Group?

    - by BGM
    Salvete! I have two servers, one hosts my email server (hMailServer on windows server 2003) and the other hosts active directory (on windows server 2008). I don't have Microsoft Exchange. In Active directory, there are user groups that have email addresses. How can I send an email to a user group? Somewhere I need to be able to connect my mail server to active directory. Maybe AD has a mail pickup folder? I can't find the information that I need. Here is a similar link, but it didn't help me. Send As Distribution Group Email Address? (I think a tag for hMailServer would be a good idea.) Thanks for y'all's help.
