Todays Sailing At Exim

Written on 8:44 PM by David S Anand

EXIM mail server & CPanel

"Server replied: 421 Unexpected failure, please try later"

Gone crazy seeing that error

Scenario

The server stopped sending and receiving emails.. squirrel mail throws error
"Server replied: 421 Unexpected failure, please try later"

checked via sending mail from root to user wow works ..but no donuts

The mails which I sent got bounced back with error
Technical details of permanent failure:
"PERM_FAILURE: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 530 530 5.7.1 Client was not authenticated (state 13)."
Checked the logs it said it is unable to locate user permission error

Google & Cpanel forum helped me again .....

Answer

The problem was /etc/localdomains file permission problem it must be "644 "
changed and restarted exim ...
The mails started working again.
