i have seen Exchange 'hide' mail that gets 4xx. it no longer shows up in the queue on the Exchange box, and it does not retry, UNTIL the smtp process is restarted, then it reappears. i used to routinely get email from a client at 4am, cause that is when his admin restarted his flaky servers :) allan -- "The truth is an offense, but not a sin"
