Sorry to bother you all with this (probably oft-asked) question, but I was wondering if someone could point me to some documentation on how one sets up filters on what can be posted to a listserv-based list? (I can't seem to find any in the LISTKEYW MEMO.) More specifically, is there a way that I could make sure that any mail sent to my list whose subject starts with "RECEIPT:" is not distributed to the list subscribers?
