I've got one subscriber who is getting munged messages, apparently due to her ISP's POP3 server not being RFC822 compliant. This only happens when I use the "resend" capability of LISTSERV (my list is moderated). Thanks to the kind help of Steve Dorner, we've apparently tracked this problem down to the two "X-From_:" lines LISTSERV inserts in the headers of resent messages. The first "X-From_:" at the top of the message does not trigger the problem, and messages with only one "X-From_:" arrive intact. But a message with an additional "X-From_:" several lines down in the header results in the insertion of two lines just before the "X-From_:". The first inserted line is "X-UIDL: ....", and the second is a blank line. Of course the subscriber's mail reader sees this blank line as the end of the headers and thus does not show any sender or subject until she opens the message. Anyone else ever see a POP3 server that choked on LISTSERV's second "X-From_:"? -rex
