I had an oddity which may/maynot have some relevance..

We subscribed someone to a list with a specific email address. They confirmed 
the subscription using web interface. Subsequently mails from that member 
were received in the way you described and were passed to mailman but did not 
get posted to the list.

I suggest you  examine the headers  of incoming mails,as they are intially 
received, and outgoing mails to those subscribers who are not receiving the 
mails.. There could be some changes being made to the headers either by the 
subscribers server or your own that is causing mails to be not delivered.
