Hello, I am running a 20,000 person weekly newsletter (no posts from subscribers we just send them one email a week) and whenever I send out the new newsletter I always get an erroe message email back from listserv which looks like ================= Error occurred while processing file 20950 from [log in to unmask]: LSWRECV error Error traceback follows ----------------------- >>> Error X'00B000BB' opening file /home/listserv/tmp/listserv.cmsut1 <<< -> Severity: Error -> Facility: Unknown (22) -> Abstract: Unspecified error (23) -> I/O mode: Block write ================= I thought perhaps that this was a bad email address since it happens every time. Does anyone know how I can begin to look into this error. Occasionally this event will crash listserv and I have to start it again manually. Is this perhaps related to part 2. Part 2 I did a get [listname] (nolock as I do to have a backup of members if I ever lose the server and while looking this over I saw a few email addresses like [log in to unmask] =?EUC-KR?B?sbiwxw==?= Is this normal? Is this some type of non-english encoding option? TIA, Garth Gillespie Web Site Admin Computer Currents http://www.currents.net
