Perhaps this is a question for MAIL-L, but I thought I would start with LSTSRV-L since it is with LISTSERV originated mail that we have noticed the following problem. We have subscribed to a number of LISTSERV lists at various sites. In the past week or so we have noticed that on some lists (e.g., INFO-VAX@UGA, LASER@FINHUTC) a lot of messages are appearing twice (at least). The messages appear to be identical, including the dates in the RFC822 headers. In the one specific case I have investigated so far, the same message was received twice from INFO-VAX@UGA; in both copies the "Received:" line from the UGA mailer was identical, indicating to me that the mailer sent the same file twice. I checked the RSCS/NJE protocol information surrounding these message and saw that the job name ("RSCSnnnn") was different in the two copies, which suggests (thought I really don't know much about RSCS/NJE) that the messages were not sent twice by some intgermediate site between UGA and DAL. Has anyone else seen this problem? Can anyone explain what is happening? I have a copies of all the recent LISTSERV messages sent to DAL if more information is needed. Please reply or cc: to me directly since I am not on the LSTSRV-L list.
