SnTT: Postmaster and Abuse defaults

Hello all. Just came across something yesterday that in all my years of administering Domino servers, I didn’t know.

It has to deal with your postmaster and abuse email addresses in your mail domain. If you don’t set those two specific email addresses up somehow (as an alias, mail-in DB etc.) then Domino will deliver anything sent to those addresses to the server Administrators group listed in the server document.

SMTP RFC’s basically require you to have those two email addresses active to allow reporting of mail abuse and the like. So Domino is smart enough to let you still get those emails, even if you weren’t smart enough to set them up yourself. It can be confusing if you don’t know Domino is doing it though, so if you didn’t already, now you know!
