[Mailman-Users] Problems reciving post from clients outside network

[Ezra Taylor]

Hello all:

I setup mailman 2.1.5 on Debian woody and postfix 2.1.5.  Now here is 
the problem.  I can send post to a mailing list as long as I'm within my 
network.  But when I use my gmail and yahoo email account, I can't send 
any posts.  I looked at the logs for the incoming mail servers and don't 
see any traffic hitting the incoming MX's.  I also don't see any traffic 
hitting the listserv.  Note, mailman works when I'm using an account 
from my organization, But when I use an account outside my 
organization.  No mail is being sent.  Again, there is no traffic on the 
incoming MX's or the listserv.  Is this a problem with our mail servers 
blocking account not coming from our domain?  Also, we have an old 
mailman(version 2.1.1) listserv runnning on redhat and postfix 1.1.11.  
This listserver has no problem honoring post coming from domains outside 
our organization.  Furthermore, I looked in the mailman log and saw the 
following error message:  Dec 19 09:15:02 2004 (1221) Warning: unable to 
setgroups([1004]).  Lastly my configure options are below.

./configure --prefix=/usr/local/mailman --with-cgi-gid=www-data 
--with-python=/usr/bin/python2.1   --with-groupname=mailman 
--with-mail-gid=mailman
