[PLUG] Postfix & Mailman

[Rob Hudson]

It's been a while since I've been on the list, but I remembered there
were many Postfix users here, so I'm joining again.

I'm setting up Mailman on a debian machine, with Postfix as it's MTA. 
I've got most of it set up, I created a list, and subscribed myself to
it via the web interface.  I cannot get Postfix to accept the mail to
the listname-request@ address.  

I've tried the following:

/etc/postfix/virtuals.proto:
# Beer
beer at euglug.org         beer
beer-admin at euglug.org   beer-admin
beer-request at euglug.org beer-request
beer-owner at euglug.org   beer-owner

/etc/aliases:
## beer mailing list
## created: 19-Apr-2002 root
beer:                    "|/var/lib/mailman/mail/wrapper post beer"
beer-admin:              "|/var/lib/mailman/mail/wrapper mailowner beer"
beer-request:            "|/var/lib/mailman/mail/wrapper mailcmd beer"
beer-owner:              beer-admin

I found a website that recommends this:

You need to setup another name for the same machine, say,
lists.domain.com, and use Postfix's transport maps to use "local" for
that. Once that's done you're good to go, since local will process your
aliases just fine.

Can anyone explain how to do this?

Also, with the above setup (virtuals/aliases), sending to
beer-request at euglug.org shows this in the mail.log:

Apr 21 23:26:36 tux postfix/smtp[13443]: EB072BD:
to=<beer-request at euglug.net>, relay=mail.euglug.net[207.189.131.4],
delay=12, status=sent (250 ok 1019456438 qp 11886)

I'm not sure why it changes the .org to a .net.  My postfix server shows
it going to the correct address:

Apr 21 23:20:30 saaz postfix/smtp[32911]: 721CE1A1BD:
to=<beer-request at euglug.org>, relay=mail.euglug.org[207.189.137.45],
delay=1, status=sent (250 Ok: queued as EB072BD)

Tips, advice, links, etc are much appreciated.

Thanks,
Rob
