[courier-users] 432 service temporarily unavailable

[Mirko Kosaros]

Hi, I checked the archive for this error message, even though a few people came across it, I couldn’t find a solution. The error occurs when trying to send messages locally piping to couriers sendmail.   Exact error message I receive is:   sendmail: ERR: submitclient: EOF from submit. 432 Service temporarily unavailable. sendmail: Unable to submit message.   Does anybody know how to overcome this error.
