For various reasons which include inter-network capability and compatibility with local mailing conventions, LISTSERV always uses the MAILER to transmit mail messages. If some MVS nodes cannot handle class M, I think the MAILER should be fixed. The problem is if I start sending replies directly from LISTSERV, some other nodes will complain that their local gateway/mail format converter (eg convert RFC822 to X400 format if they use a X400 mailing package) and suchlike are not working any more. And I'd say that UCLA-mail would not intercept mail any more since it would probably come in Netdata format (Peter?) Please note that FRECP11 will be down from tomorrow (19th) to the 24th of december. Please try not to start another heated argument on this list since the FRORS31 people will probably purge any file in excess of 150 left in the FRECP11 transmitter's queue and the more files there are, the more they will be inclined to purge some of them... ;-) Eric
