[Solved] 451 Temporary local problem - to one domain
I've been trucking along just fine until last Thursday, then this error pops up for multiple accounts on my server to multiple accounts to that domain. All other mail flows like a river.
I've preformed no updates to the OS nor ZCS since I moved from 7.1.3 to 7.1.4 several weeks ago.

If I send a test message to email@example.com, then I get a 550 Authentication Required bounce from that server.

I'm running :
One last bit of information, I have emptied the deferred queue of the messages going to the lumpkincounty.gov domain and created a new message just from me to their admin, and it still gave me the same error. I was concerned about one of the messages being "corrupt" and causing the issue, but that isn't the case it seems.

If anyone else out there has a (sort of) exact system as mine (see above). I'd like to give you a test e-mail address to send to just to see what happens on your system. Just send me a PM.
