Virtual Users, Aliases, and Quarantines

[erikogan]

I’m looking to add PMG to our current setup, and have it replace our ancient virus, spam, and quarantine system (Maia Mailguard).

The problem arises in that we accept mail for at least a dozen domains, and a lot of those use Postfix’s virtusertable to redirect addresses within them to the correct local user. In our current setup, Maia is downstream of the virtual address lookups. I’d like each user to have a single quarantine regardless of the incoming address.

I definitely want to use PMG as a border MTA/proxy, so as I see it, this leaves 2 options:

1. Add the virtusertable & aliases to the PMG setup.
2. Configure PMG to have a user/quarantine for every virtual address.

To be honest, I’m not crazy about either option, but #1 is definitely more appealing than #2.

I’m comfortable enough with Postfix that I’m pretty sure I can get that working (though I have not looked at PMG’s specific postfix configuration yet). I just want to be sure that if I choose do this I won’t cause issues with other portions of PMG. Especially since some of those virtual addresses point to remote emails.

Is this what people would recommend? Am I missing something obvious? Is my whole approach backwards somehow? I’d love feedback on this.

If you have a setup where the users are configured in an LDAP you could use that as source of which mail belongs to which mailbox
Apart from that I think this cannot be done (PMG stores each mail into the quarantine for the mailbox and has no concept of aliases (apart from LDAP)

I hope this helps!

Thanks for your reply!

I’m definitely intrigued at the idea of moving this information into LDAP, but I’m not entirely clear on how to represent (for example) erik@domain1.net, mr.e@domain2.com, dr.zaius@domain3.org, etc. are all owned by the same mailbox (mine) in LDAP. Would it be possible for you to point me at an example of that?
