[Mailman-Users] no relaying

[karazoe at pacbell.net]

Hello,

I'm new to the whole Mailman thing, but I like it so far.  
Unfortunately, I 
can't get any of the posts and I don't know why.

Symptoms:
- All of the admin/managemnt notices get sent (welcome to 
list, confirm 
subscription, etc.), but none of the mail sent to the lists 
get sent out to the 
members.

- This occurs whether or not the members are on the local 
system or not.

Setup:

Postfix - postfix-20011125-1SASL
Redhat 7.1
python-1.5.2-30


log/messages:

Mar  5 12:46:59 nigel CROND[16220]: (mailman) CMD 
(/usr/bin/python -S 
/home/mailman/cron/qrunner) 
Mar  5 12:47:02 nigel postfix/smtpd[16221]: connect from

Mar  5 12:47:02 nigel postfix/smtpd[16221]: disconnect from 
mta7.pltn13.pbi.net[64.164.98.8]

and I repeatedly get:

Mar  5 12:49:00 nigel CROND[16229]: (mailman) CMD 
(/usr/bin/python -S 
/home/mailman/cron/qrunner) 

every 1-2 minutes.


I am a hobbyist with no formal training in Linux (only what 
I've picked up over 
the last couple of years playing with it).  Everything else 
works fine.  
Postfix works with all my email accounts except not with 
Mailman.

Any help is greatly appreciated!

Thanks!
