It's not like these emails are being sent to both me and the list address.  They are being sent to list1, list2, list3, and list4.  I happen to be on all of them for monitoring purposes.  I'm sure there are others within my organization that are on more than one of these lists.  We have administrators that like to see that their message has gone out to all the student announcement lists.

Could the address be a gmail address? Gmail looks at message-Ids and automatically removes duplicates, and the same initial email to multiple lists, will all have the same message-id.



No, not Gmail.  My address is in-house Exchange and my test "student" account is Microsoft Live at edu which I would assume is a really, really big Exchange system.  So might this not be a GNU-Mailman behavior ?
