Shahar:

Sometimes when you SEND a message ONCE to a list, the LISTSERV receives
it TWICE because

1) the transport system between your client SMTP (MTA) and the LISTSERV
server SMTP (MTA) did not properly acknowledge the receipt, but
nevertheless the server did receive/process it; the client did not know
that and sent it again. Or ...

2) some recipients' MTA are broken and when they reject (bounce) a
message, they send it back to the list making it look like the original
message and sender!  This is very annoying and misleading.  You have to
check the LISTSERV error message RECEIVED line headers very carefully in
order to get a clue as to the broken [log in to unmask]
