All that was done to Move my email accounts is they changed the mx records at their end. I sent them a support request and their reply was that they had moved my domain name from the list of local domains to remote ones.
I changed the smtp email host to smtp and have all of the smtp settings setup for the host that the email accounts actually reside on and I still get an error message.
What about other settings within the email options page? Should some of those be different?
Here is what I currently have:

E-Mail Transport Method smtpauth
E-Mail Linefeeds CRLF
Use MIME HTML When Sending Emails true
Send E-Mails true
Email Archiving Active? false
E-Mail Friendly-Errors true
Email Address (Displayed to Contact you) [email protected]
Email Address (sent FROM) [email protected]
Emails must send from known domain? No
Email Admin Format? TEXT
Send Copy of Order Confirmation Emails To <[email protected]>, <[email protected]>, <[email protected]>

SMTP Email Account Mailbox orders+tilvee.com
SMTP Email Account Password ******
SMTP Email Mail Host 74.220.202.35
