We are getting an error message and I'm hoping someone can shed some light. We recently moved our mail server to a new location, and therefore had to change DNS. About 12 hours after we had it in place I'm starting to see in the logs the following errors:
Unexpected connection response from server: 421 SMTP service not available, closing transmission channel
Those are in the IMail log files? If so, it sounds like it isn't directly related to the move -- it would indicate that IMail is connecting to the "wrong" IP for mailservers it is trying to connect to. Is it happening with E-mail to all domains, or just some?
