I apologize if I am asking a question already answered, but my problem isn't really that I haven't found an answer. I have, in fact, found a half-dozen different "solutions" to my problem, tried them all, in various combinations, and have been consistently unsuccessful.
The goal
All I want to do is change the envelope "from" address for all email sent from
[email protected] to
[email protected], always.
What I've already done
I am running Apache, PHP, and sendmail on CentOS 5.5,
[email protected]. We have an SMTP server at 192.168.0.4. The domain's email accounts are all at @domain.org.
I have successfully set up "smart host" using this line in the sendmail.
mc file:
define(`SMART_HOST', `192.168.0.4')dnl
Then I set up masquerading, and was hopeful this would solve it. I have this in the .
mc file:
FEATURE(`masquerade_entire_domain')dnl
FEATURE(`masquerade_envelope')dnl
FEATURE(`allmasquerade')dnl
MASQUERADE_AS(`domain.org')dnl
MASQUERADE_DOMAIN(`domain.org.')dnl
MASQUERADE_DOMAIN(`localhost.localdomain.')dnl
This rewrites "to" addresses, but not "from" addresses. Testing from the command line:
sendmail -v
[email protected]
Always is shown from the local user (in this case root, or my local user account).
I had read that "sendmail" command sometimes bypasses masquerading. Nevertheless, using the "mail" command has the same result.
After that, I have explored several "solutions", including:
mailertable
virtusertable
FEATURE(`accept_unresolvable_domains')dnl
LOCAL_DOMAIN(`localhost.localdomain')dnl
FEATURE(`genericstable')dnl
/etc/mail/access file
/etc/mail/local-host-names file
/etc/mail/trusted-users file
All to no affect.
The last thing I've tried
So, I decided to go in a different direction, and try to set the envelope "from" address via PHP, using either the configuration in /etc/php.ini, or adding the -f parameter to the mail() function or to sendmail command.
If I run this command:
sendmail -v -f
[email protected] [email protected]
I get this error in /var/log/maillog:
Mar 30 08:56:16 localhost sendmail[24022]: p2UCuE8w024022:
[email protected], size=5, class=0, nrcpts=1, msgid=<
[email protected]>, relay=user@localhost
Mar 30 08:56:19 localhost sendmail[24022]: p2UCuE8w024022:
[email protected],

Mar 30 08:56:19 localhost sendmail[24022]: p2UCuE8w024022: p2UCuE8x024022: DSN: User unknown
Mar 30 08:56:23 localhost sendmail[24022]: p2UCuE8x024022:
[email protected], delay=00:00:04, xdelay=00:00:04, mailer=relay, pri=31029, relay=[192.168.0.4] [192.168.0.4], dsn=2.0.0, stat=Sent (Ok: queued as B5E2E40E0A2)
Which is basically a "User unknown" 550 error.
Help
Please help. What do I need to change? Should I just start over in the sendmail.
mc file? It has a ton of config options stuffed in it, over days of trying things. Why is changing the envelope "from" address via the command line generating a "User unknown" error?
