I've searched this forum and found lots of similar problems, but mostly about SENDING mail rather than RECEIVING it. I've tried some of the solutions suggested in the similar topics, but nothing has worked, so its possible that I've messed things up worse.
Again, I can send emails, but not recieve. Any help would be appriciated!
I've had exactly the same problem some days ago.
The strange thing was that it was only with one of the domains.. all other domains did not have the 554 error!
I deleted the account/domain, and remade it.. after this all was fine again!
If you are having the 554 problem with only one domain, try what I did, and it might fix it also
