Domain does not exist 4220.127.116.11 when sending email from exchange 2010 mailbox
Posted on 2014-10-07
I have an email server with 4 domains on it. Three out of the four are working but the fourth is getting the error stated above.
All the domains are registered but different registrars.
I turned on protocol logging but it only verified what I already knew - domain does not exist.
From the send connector, mail goes to a smarthost that is also functioning properly.
All assistance appreciated
