Over the last 3 weeks, I've received a slew of rejected responses-to- confirmation-requests. All of the responses have been addressed to owner-LISTSERV They appear to be automated 'REPLY's ( i.e. sender appeared to type REPLY - not type the address from scratch) The only thing that they seem to have in common is that the FROM and/or first RECEIVE header has the string "MSMAIL" ... somewhere in it..... Anyone else seen this ? I've done test subs from IBM, VAX, and unix systems and can't reproduce the problem, so I don't think it is a problem with LISTSERV -mike
