Hello!

At work I have the following real-world postfix setup:

mydomain = redoaksw.com
mydestination = local.redoaksw.com # note that this domain doesn't exist
virtual_mailbox_domains = redoaksw.com

I installed mailman and created the list 'test1@redoaksw.com'. So far so good, however the "virtual-mailman" alias map mailman generates does not work.

The problem is as follows : 1) the map contains entries such as test1@redoaksw.com test1 2) postfix converts "test1@redoaksw.com" to "test1" as it should, and then qualifies the address with $mydomain, test1@redoaksw.com. (note: this does not actually create a loop) 3) with the address test1@redoaksw.com, postfix hands the message to virtual(8) which looks in the virtual_mailbox_maps and correctly reports no such user

The solution is simple -- change the map to: test1@redoaksw.com test1@local.redoaksw.com

In this scenario, after the virtual_alias_map rewriting, postfix will hand the message to local(8) which will find the mailman command in $alias_maps.

To this end I created the attached patch to mailman. It WorksForMe, but is not yet complete enough to include in the next release. I need some assistance in polishing it for inclusion. The core of the patch is simply to optionally fully-qualify the map value in _addvirtual() in Mailman/MTA/Postfix.py.

The parts I need help with are :

+  What are good names for the parameters (in mm_cfg.py and the
    mail list object)?  I'm not convinced you want to be stuck
    with the names in my patch forever :-).

+  How do you handle additional parameters on maillist objects?  I
    noted that __getattr__ fails when the web interface tries to
    load the current value from a list created before the
    parameter was added.

+ Should the default value for 'local_domain' (as it is currently
    called in my patch) be '' or None?  I would generally choose
    None, but that seems to not play well with the web interface
    (it shows "None" instead of nothing).

+ Do I need to do anything with any translation files with regards
    to the new list parameter?
