[Mailman-Users] re: Mailman and Postfix *2*?

[Jeremy Butler]

Postfix 2, Mailman, and I were all getting along well . . . until it came 
time to set up virtual domains.  I've read through the instructions on it 
in Postfix 1, Postfix 2, Mailman, and several Mailman-Users posts; and now 
I've gotten myself totally confused.

Can anyone offer me a bit more guidance?

Here's what I'm trying to do:

A single Linux RH8 computer runs Postfix *2*, Mailman 2.1.1, and Apache 
1.3.27.  Its main domain name is www.tcf.ua.edu , but it also hosts a 
second domain name on a separate IP number:  www.cinemastudies.org .  I 
want to run separate Mailman lists on the two domain names.  I also have a 
small number of user accounts on www.tcf.ua.edu .

Here's what I've done:

1.  Successfully installed Postfix 2 and gotten it to receive/send mail on 
www.tcf.ua.edu .

2.  Successfully created Mailman lists on www.tcf.ua.edu .

Now here's where things get wonky as I attempted to add a virtual domain.

3.  Edited Postfix's /etc/postfix/main.cf by inserting lines from 
sample-virtual.cf:

virtual_alias_maps = hash:/etc/postfix/virtual
virtual_alias_domains = $virtual_alias_maps

Should this second one be:

virtual_alias_domains = 
$virtual_alias_maps,hash:/usr/local/mailman/data/virtual-mailman

4.  Edited /etc/postfix/virtual and put these lines in it to create a 
virtual domain of www.cinemastudies.org:

www.cinemastudies.org anything (right-hand content does not matter)
@www.cinemastudies.org                @www.tcf.ua.edu

5.  Ran "postmap /etc/postfix/virtual" to create /etc/postfix/virtual.db.

6.  Added the following to the end of mm_cfg.py:

MTA = 'Postfix'
POSTFIX_STYLE_VIRTUAL_DOMAINS = ['www.cinemastudies.org']

7.  Ran "/sbin/service postfix restart".

So far, I haven't received anything on my virtual domain 
(www.cinemastudies.org).  Any thoughts as to why?

Should myhostname be entered twice--once for the main domain and once for 
the virtual one?  Like this:

myhostname = www.tcf.ua.edu
myhostname = www.cinemastudies.org

Should I add anything to:

mydestination = $myhostname, localhost.$mydomain

Thanks for the help!
