Over the last several days, members of our Domino administrators group kept receiving emails addressed to postmaster@ourdomain.com. The emails were being generated from an agent in a mail file that sends out a auto reply. It just so happens the postmaster account is also being used on our antispam server to let people know if they have a blocked attachment. So the auto reply was trying to send an email back to the antispam server and of course couldn't find a email account for it. Searching Lotus' knowledgebase, I found technote #1106677. Evidently to be fully compliant with RFC 822 a mail system must accept messages addressed to postmaster@domain. If no match is found (i.e. no user or group is assigned this address) Domino will delivery the message to the administrator(s) by default. The solution is to associate postmaster@yourdomain to a mail account. So I learned something new today.
