[Mailman-Users] mailman-postfix problem

[Lie, Jafaruddin]

Hi gang

Just joined the mailing list *waves to everyone

I have problems getting mailman to run with postfix. Here's the story:
mailman installation went ok and it ran ok with sendmail. When I
installed and used system-switch-mail to switch to postfix, the problem
began.

The setup: 
I am setting mailman to run internally, so we have local mail accounts
on my fedora box (jafar at fedora.x.x.x) not accessible to the outside
world, only locally and anyone on the domain x.x.x. 

The postfix installation went ok, I can send and receive mails from my
local accounts just fine. I configured mailman in mm_cfg.py to use
postfix as the MTA. I followed the instruction on
http://www.gnu.org/software/mailman...all/node13.html.

The problem:
I created one mailing list, with 3 email addresses suscribed to it. One
is my local mail account (root at fedora.x.x.x which is forwarded to
jafar at fedora.x.x.x) and two are addresses from x.x.x, lets call it
jafar at x.x.x and daryl at x.x.x. These are real email addresses, accessible
from the internet 

With sendmail, the mailing list works just fine. All the accounts can
send and receive emails from the list.
With postfix, only the local account can. The other two email addresses
can send to the list, but they will not receive anything from it. The
error message I get from /var/log/maillog:

That's when I send from my real email address to the list. Similar
error, about User unknown in local recipient table.
The only way I can get it to send is if I add the two email addresses
into the /etc/aliases file, something like daryl: daryl at x.x.x.
Considering the list will contain a lot of people, I don't want to be
entering the aliases in the /etc/aliases when mailman obviously has the
email address stored in /etc/mailman/aliases and
/etc/mailman/aliases.db. 

What I have done:
I have ran postmap and postalias to /etc/aliases/ and
/etc/mailman/aliases, have changed /etc/postfix/main.cf, the alias_maps
to read: 
Code:
alias_maps = hash:/etc/aliases, hash:/etc/mailman/aliases


I am at lost here, and about to pull out my hair...... Any suggestions? 
TIA.
