If the two addresses that are not receiving replies to commands have the same host and the other 2 that do receive replies to commands have the same host; Then I suspect that the first host has instituted a weak anti-spam feature to reject mail with MAIL FROM:<> blank Listserv sends responces to commands with the MAIL FROM: <> (blank) for several reasons and List mail is not sent that way. This of course *IS* in compliance with the RFCs and rejecting them is *NOT*. John
