The bounce message *can* be generated by the sender's mail host. Or it can be by the recipient's mail host, or anyone in between. It all depends on the reason for the bounce and at what stage it failed. My honest guess why people aren't getting bounces for bad addresses... because the ISP is tired of sending back 300 bounces to someone who's address just happened to be picked by a totally unrelated windows user with an infected machine. So they just blackhole all bad address bounce messages knowing that 99% of them will be BS after effects of a windows virus. The remaining 1% of legit bounces are just acceptable collateral damage. -chris <http://www.mythtech.net> ___________________________________________________________________________ To unsubscribe send a mail message with a SUBJECT line of "unsubscribe" to <[EMAIL PROTECTED]> or <[EMAIL PROTECTED]>
