Postfix - forward email to another address and keep a copy in the mailbox
 
Hi, I have postfix setup using LDAP and virtual domains, here is the line that got forwarding working:
virtual_alias_maps = ldap:aliases, ldap:virtualforward

This forwards the mail to a different address properly but I've had requests for it to keep a copy in the mailbox.

I have a field in ldap for forwarding yes/no then a field for forward address. I have a couple business partners that have their email at my domain forwarded to theirs but they also want a copy to stay on my server so they can check it(and reply or whatever) from my domain.

How do I keep a copy?

in the alias map, add both addresses: the forwarded address and the local. Postfix is smart enough to not get into a loop and retains one copy for the local address;

from a working setup here at my workplace:
Code:

miguel: miguel myexternaladdress@hotmail.com

In my LDAP directory I included both forward address and the local address. When an email is sent to the local address a copy is stored in the local address mailbox, which is exactly what I want.

The problem is the forward address receives multiple copies of the email.

The setup I am trying to achieve is a email archive. All email sent to the address forumadmin@ example.net will also goto the email address forumadmin.archive@ example.net. When I check the forumadmin.archive mailbox multiple copies of all email reside in this mail box.

postfix/virtual[5276]: 356CC540D117: to=<forumadmin.archive@ example.net>, relay=virtual, delay=0.1, delays=0.06/0.01/0/0.03, dsn=2.0.0, status=sent (delivered to maildir)

postfix/virtual[5276]: 356CC540D117: to=<forumadmin.archive@ example.net>, orig_to=<forumadmin@example.net>, relay=virtual, delay=0.1, delays=0.06/0.01/0/0.03, dsn=2.0.0, status=sent (delivered to maildir)

postfix/virtual[5276]: 356CC540D117: to=<forumadmin@ example.net>, relay=virtual, delay=0.11, delays=0.06/0.01/0/0.03, dsn=2.0.0, status=sent (delivered to maildir)

As you can see from the above log file, mail sent to forumadmin@ example.net is sent to the archive account, but multiple copies are delivered.
Does anyone know why this occurs?

Try this guide I wrote up here with LDAP:

Keeps a local copy, forwards the email, and doesn't deliver multiple copies.
