Greetings!

  a. We have two listserv services (aflcr and pause-cafe) running on  
the same server  (@list.uvm.edu)

  b. We have people who want to post the same message to both lists,  
so they put both list addresses in their message AND they are set to  
receive copies of the mail they post to both lists (i.e. subscriber  
setting for both lists has the setting: Default-Options=  
Repro,Subjecthdr)

  c.  However, when sending messages to both lists they are reporting  
that only one copy of the message is coming back to them, instead of  
one from each list.  There are conflicting reports about which list  
sends back the one message that they do receive ... it might be from  
either list but not both!

  d.  The sender is left to wonder if the message only made it through to
one list and not both.

My question to the lstown-l forum is:  Why are message senders only  
receiving one copy of their message (from one list or the other), when  
they should be receiving a copy from each list?

I'm thinking there must be a filter or de-duping mechanism in the  
sender's local email system that is somehow filtering out the  
duplicate because it is clear from the logs that the messages are  
posted to both lists ... and only the person sending the message to  
both lists seems to be affected by receiving the message from only one  
list (i.e., subscribers to both lists are seeing both messages).   But  
could there be another reason?  And why is it only the message sender  
who is affected?

Any help or insight would be much appreciated.

Thanks!
