[Mailman-Users] Mailman not delivering mail to recipients

[Jewel]

I am running:
Red Hat Ent. 5
Mailman 2.1.11
Postfix 2.3.3

When I send a message to a list it will successfully post to the 
archives but not to the recipients.  I can't find anything in any error 
logs and postfix is saying it successfully sent.  I am trying to look at 
the archives for any insight.  Any ideas would help.
