This is just what I was looking for. Now if I want all subscribers to get the message. Would the poster just send a message to the list without the TOPIC command in the subject.

For purposes of review, it takes three "things" to do topics: 1) appropriately configured list definitions for TOPICS= DEFAULT-TOPICS= 2) subscriber who has SET their preferences accordingly 3) a poster who chooses the corect topics and codes the SUBJECT: line appropriately The following is the syntax/semantic for your particular need: TO: ABCD@listhost SUBJECT: TOPIC1: rest of description notice the use of colon and the need for "whitespace" A futher example, it you wanted to send to folks who were interested in either topic1 or topic9 SUBJECT: TOPIC1,TOPIC9: rest of description Hope this helps. /Pete Weiss
