It could be that the network/machine went down while the delivery was happening, or some other reason. Normally, another attempt to deliver the message will follow. >ie.. too many hops This means that in trying to deliver the message to it's destination, mail went through too many machines. Most mailers have a hop count upper limit and bounce mail when this limit is reached. It prevents mail from looping forever due to mailer misconfiguration or user forwards. >ie.. unknown user This means exactly what it says. The mailer where the destination address points to does not know about the user in question, and returns the "user unknown" code. This is just of the top of my head, but I believe that these codes are documented in RFCs (RFC821/822). +-----------------------------------------------------------------------------+ | Acacio (Casey) Carvalho | e-mail: [log in to unmask] | | VMS Technical Support | alternate e-mail: [log in to unmask] | | Micro & VMS Support, CCIS | | | York University, T103 Steacie | | | North York, Ontario | Tel.#: (416) 736-5257 x 22686 or | | Canada M3J 1P3 | (416) 736-2100 x 22686 | +-----------------------------------------------------------------------------+
