I am trying to set up to read and send mail via Gmail with my [email protected] domain name.
Receiving mail is no problem. But when I want to verify my account to send mail (imap) I get this message:

The response was:
550 5.1.1 The email account that you tried to reach does not exist.

WHM Email Routing: Remote Mail Exchanger
DNS MX records set: aspmx.l.google.com, aspmx2.googlemail.com, etc
I checked my DNS setting on intodns.com, everything OK.

I tried setting SMTP server for sending mail: [email protected] (and aspmx.l.google.com)
SMTP Port: 465

Still I receive the error mail from google when I click verify in the Gmail window.
What's wrong?
