Revised LISTSERV does not recognise that "Resent-Reply-To" should over-ride "Reply-To". This is disastrous for a list which is set up to "respect" the "Reply-To" field. Today I forwarded a message received from the MAILBOOK distribution list to colleagues, using a local list. I gave the command "REPLYTO SELF" to avoid their comments going to the original list, and verified that MAIL inserted a "Resent-Reply-To" field. One copy was bounced to me as postmaster, on account of a mis-spelt userid, and I noticed that the "Reply-To" field pointed to the ORIGINAL LIST. Bad enough that replies should go to the entire local list, but the replies will now go to MAILBOOK@DEARN, as few enough people bother to look at the header of an outgoing message. Niall
