I'm receiving a lot of 421 rejects with:
Unexpected connection response from server:
421 mails from 74.254.46.133 refused: local dynamic IP address

That IP address is not dynamic. The reverse DNS is correct.
Does anybody recognize the text of the message? I'd like to confirm that
there are no popular DUL lists showing 74.254.46.133 as dynamic, but the 421
message says very little. DNSReport says it's clean. I've tried to contact
some postmaster accounts (using Yahoo.com, since I can't use my own mailer)
but they appear to be RFC ignorant too. Unfortunately, it's not just one ISP
in Germany and I'd like to understand if there's anything I can do on my
side.
Isn't it a web hosting provider? If so, maybe they have some web
form for contacting them.
