How to... reply 450 invalid recipient instead of 550 Invalid recipient...
I've moved some more domains over to my new server that I've been building with your assistance. :D While I get the configuration finalized, I'd like to send temporary failures, rather than permanent failures, so that I can alter my configuration and have the sending server retry. I only have filters that result in 550s - mostly for spam-control measures. Is it possible to reduce the severity of an invalid user, so that I get the chance to correct any remaining configuration problems, rather than just rejecting the mail entirely? Thanks again!

It's a reporter filter in OpenSMTPD that gathers IP addresses for failed auth and then writes them to maillog: Nov 27 01:02:26 host smtpd[29787]: auth-reporter: failed authentication from user=username address=113.172.130.229 host=static.vnpt.vn Fail2ban takes it from there.
