In my application environment, I provide my users with the ability to send emails to their customers. It uses the php mail() function.
In my previous server, sendmail was the mailer configured for php. In this new environment, it uses the Postfix version of sendmail.
The php.ini file specifies: sendmail -i -t as the mail command.
When I send mail from a customer (on their behalf), I use the additional argument that is to be passed to sendmail to specify the 'From' portion of the envelop. I.e. the mail() function is invoked like:
mail( $to, $replyTo, $subject, $headers, "-f $envelopFrom");
However, this does not seem to be working correctly.
It seems that postfix thinks the user sending the amil is '1sit' where PHP is running as 'ezom'. Additionally, it does not seem to be recognizing the '-f $envelopFrom' argument.
Specific maillog entry is below. This email was sent in a fashion that should have been:
-------------------
To: tonyb@1sit.com
From: test@thisIsATestURL.com
Subject: Test email
Test message.
------------------------
However (see below) it seems that Postfix did a setuid to '1sit' rather than 'ezom' and also spamd seemed to fail the message (??).
Also, there was no failed delivery response in 1sit's inbox (as indicated in the log) or on my other 1sit server.
Can you help me figure out what's going on?
I need to be able to send mail on behalf of my clients with any failures being returned to the client address specified by $fromEnvelop instead of me (or any of the other domains on this system). I.e. the client may configure their environment to send from 'info@clientDomain.com' and any reply-to or failures should go to that address (which may or may not be hosted on this machine).
Postfix log info (I added comments in parentheses):

(above also seems correct but don't know about the nrcpt=1 option)

(Don't think the above should be going setuid 1sit but instead should be setuid 'ezom' which is what php was running as)
