How can I set it up so I can use VERP with Plesk?

[Toxalot]

I'm just learning about VERP in order to allow emails addressed to bounces+token@example.com to be delivered to bounces@example.com. But I am always leery about following instructions that are not specifically designed for Plesk.

Can I edit /etc/postfix/main.cf file? Does Plesk use that file? Will it overwrite my changes at some point? Do I have to restart anything after making changes?

Anyone?

I gave it a try. I uncommented this line in /etc/postfix/main.cf and restarted Postfix.

recipient_delimiter = +

Unfortunately, I can't seem to get it to work. Messages sent to addresses that include the delimiter are no longer rejected, but they don't appear to be delivered anywhere either. Here's an excerpt from the maillog:

Jul  8 12:14:36 cl-t082-392cl postfix/smtpd[28723]: 6E98A1A404CC: client=mta02.eastlink.ca[24.224.136.13]
Jul  8 12:14:36 cl-t082-392cl postfix/cleanup[28727]: 6E98A1A404CC: message-id=<6.1.2.0.2.20130708131351.24958960@pop.eastlink.ca>
Jul  8 12:14:36 cl-t082-392cl postfix/qmgr[28717]: 6E98A1A404CC: from=<me@example.com>, size=1343, nrcpt=1 (queue active)
Jul  8 12:14:36 cl-t082-392cl postfix/pipe[28752]: 6E98A1A404CC: to=<bounces+test@ourdomain.com>, relay=plesk_virtual, delay=0.22, delays=0.15/0/0/0.07, dsn=2.0.0, status=sent (delivered via plesk_virtual service)
Jul  8 12:14:36 cl-t082-392cl postfix/qmgr[28717]: 6E98A1A404CC: removed

The way I read that is that Postfix is successfully handing the email off to plesk_virtual. But plesk_virtual seems to be silently rejecting it. I tried changing the recipient_delimiter to a minus sign, but that didn't make a difference. I tried setting up a .qmail-default in the /var/qmail/mailnames/ourdomain.com/bounces directory, but that didn't help.

I really need this feature. Is there no one doing this successfully on a Plesk server?

postfix-local (plesk_virtual) and other Plesk components do not support this feature.

What do people do instead? I need a way to reliably link bounce messages with the related database record.

I'm not sure, but maybe setting some custom mail header will do the trick?

 

[Toxalot]

I do have a custom mail header and that is what I am using now. But for about 10% of the bounces, the original headers are not included.
