What he needs is a "super-list," which is a list with other lists defined as sub-lists.  He can then send the message to the super-list and it will go out to all subscribers in the defined sub-lists.

Subject: Spam filter exception customization

One of the departments at my university relies upon Listserv lists for dozens of the courses they offer. In one set of those courses, each course has its own separate list. A problem has arisen where an instructor who has a legitimate need to post the same message to each list periodically gets marked by Listserv as a spammer. When this happens, Listserv bans him from posting any further messages for 48 hours, which is very inconvenient.

This is with Listserv 14.5. How can I set up Listserv to allow an exception to the spam filter mechanism to help out this instructor?
