Just nit picking here but the "Well Known Port" 587 is assigned http://www.iana.org/assignments/port-numbers as the submission port. Assuming the RFC you're referencing is RFC 2476 Message Submission http://www.ietf.org/rfc/rfc2476.txt it does not reserve SMTP AUTH for use only on port 587, nor does it require SMTP AUTH to be used at all. In fact, it doesn't even require authentication! Section 6. Optional Actions states "The MSA MAY do any of the following:" followed by 6.1. Enforce Submission Rights The MSA MAY issue an error response to the MAIL FROM command if the address in MAIL FROM appears to have insufficient submission rights, or is not authorized with the authentication used (if the session has been authenticated). "MAY" is not "MUST". -- [EMAIL PROTECTED] "The avalanche has already started, it is too Rod Dorman late for the pebbles to vote." � Ambassador Kosh To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
