Using VERP on Postfix server
Reuben (Plexus IT)
Hey All,
I
am trying to use email sub addressing (VERP) on my Postfix server. To do this I
should be able to add tag to an email address
return+tag=bob...@give2partners.org and still receive the email to ret...@give2partners.org.
I have activated the following in postfix main.cf
file according to http://www.postfix.org/VERP_README.html:
recipient_delimiter = +
forward_path = $home/.forward${recipient_delimiter}${extension}, $home/.forward
propagate_unmatched_extensions =
canonical, virtual
But when I send an email to
return+tag=bob...@give2partners.org it just disappears and does not give a
bounce or anything. Can you point me in the direction of what I am doing wrong
in my configuration.
I am running Postfix 2.3.3-2.1.el5_2 on a Parallels Plesk run server.
Thanks

Here is the relevant part of the mail logs as far as I can tell. Would you
be able to help me understand what is happening to the email with my VERP

None the above logging is from Postfix.

Apparently, Postfix received a message via SMTP from 127.0.0.1.

That is not Postfix. I know this, because Postfix does not log
dirname information.

That is not Postfix. I know this, because Postfix does not log
hook_dir information.

That is not Postfix. I know this, because Postfix does not log
recipient[number] information.

That is not Postfix. I know this, because Postfix does not log
"handlers dir" information.

call_handlers? are your running qmail?
what are these "postfix-local" and "spf filter" in your logs (the latter
breaks syslog format. don't put space in process names).
anyway, the log line above shows an error that you may want to fix.

whatever program your exec from pipe is borked (returns OK when it fails).

Reuben (Plexus IT)
let me brain dump all I know here. I am using an instance of Postfix that is
running on a server setup using Plesk control panel. From what I can make
out that means that means they have configured Postfix in a nonstandard way.
The reason that Qmail seems to appear is that originally Plesk only support
Qmail and when they implemented Postfix they retained /var/qmail/mailnames
as the email directory. Sorry I have no idea about the SPF stuff, seems to
be how postfix is setup on a Plesk server.
The reason that the chdir is not working is that there is no mail name
return+test=bob...@give2partners.org. I need it to strip the email so it
delivers it to ret...@give2partners.org address. Can you tell me what is
wrong with my VERP configuration that means this is not happening.
I have added the following to the configuration file according to
http://www.postfix.org/VERP_README.html:
recipient_delimiter = +
forward_path = $home/.forward${recipient_delimiter}${extension},
$home/.forward
propagate_unmatched_extensions = canonical, virtual
I appreciate any help.
Thanks

Above, the plesk_virtual service can't find the user yet it reports
success to Postfix (next logfile record).

The plesk_virtual service has returned "successful delivery" (process
exit status 0) to Postfix, therefore Postfix deletes the queue
file.
Instead, the plesk_virtual service should have returned "user
unknown" (process exit status 67) to Postfix. Process exit status
codes are defined in /usr/include/sysexits.h.
So you have two problems:
1) Making the plesk_virtual service recognize username with extension.
2) Making the plesk_virtual service return non-zero process exit status
numbers in case of error.

the email directory is not the issue. your logs suggest that qmail is
being used.

with postfix, you do this with
recipient_delimiter = +
that's all you need with postfix. you need to check that your system is
using postfix and only postfix. mixing MTAs will only cause problems.
