[Mailman-Users] messages not being sent

[Ira Rosenblum]

I set up a mailing list using Mailman 2.1.6 and all the configuration  
seems correct, yet some messages sent to the list are not making it  
to the group members (even though the messages appear in the list  
archives). Has anyone else had this problem and if so, what did you  
do to solve it? I am not a "tekkie" so the simpler the instructions,  
the better!
