550-Several RFCs state that you are required to
have a postmaster 550-mailbox for each mail domain. This host
does not
accept mail 550-from domains whose servers reject the postmaster
address.
I'd just like to point out that there are good reasons for someone to
reject the postmaster address.
Just yesterday, I logged in and was greeted by over 4,000 rejected
emails, all sent to postmaster(a)bytesmiths.com. One or more spammers
had just started forging that as the "From:" address in their vile
utterances, and now I was getting all their "backscatter" from spams
that failed, for whatever reason, to be delivered. They were coming in
faster than I could delete them. So I was forced to disable the
postmaster address.
I am just a tiny one-person ISP, specializing in hosting for artists
and non-profits. I don't have time to deal with this. So I'll leave it
disabled for a week or so, then cautiously turn it back on.

star in a middle-aged galaxy in a middle-aged universe. Enjoy the ride
