Just checking, but aren't all MTA supposed to do that? Can't remember exactly the RFC but somewhere between 821-823 if I recall correctly? There just seems to be a lot of discussion about KLEZ and that you can't determine the sending listed in the envelope (which is correct sometimes and forged other times), without a packet sniffer. Obviously not the case with SIMS, but many partially implemented servers out there? ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
