Just addressing this part, since the other part (Setting From at the Queue level and/or using $OverrideOutgoingMailFrom) has been addressed. RT 4.2 finally dropped internal SMTP support because it was slow and easily dropped email if there was an upstream error. Many simple relay clients are vulnerable to the same problem if your smarthost ever drops offline while you're trying to relay. Postfix/exim/sendmail in smarthost only mode avoid this failure. -kevin
