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 We have not had this error before so I'm assuming it has to do with the location change. Is this something that has to do with the DNS changes, or is there a problem with our mail server? At the time of the move we upgraded from IMail 8.05 to 8.12. I would appreciate any feedback.
