It may not be a LISTSERV or a MAILER problem. We have had a recurring line noise problem between here and our downstream node. Line hits cause the usual RSCS error recovery so files eventually get through, but I have noticed occasions (with higher probablility than I would have expected) where the line fails after the receiver has accepted a transmitted file, but before the sender realizes the file can be deleted. After error recovery, the same file gets retransmitted.... /JSFisher
