I have multiple email addresses on my lunarpages domain, e.g., myname@mydomain.org, info@mydomain.org, etc.

I have my lunarpages mail set up to forward all my mail to gmail accounts, which I check online and via thunderbird. But I can also check the lunarpages mail accounts directly (i.e. not via gmail).

I send all my mail via gmail, but identified as myname@mydomain.org.

My problem is that for two days now I'm not getting incoming mail on my lunarpages domain. Gmail sent this error message when mail sent yesterday from myname@mydomain to hername@mydomain.org bounced:

Technical details of temporary failure:
TEMP_FAILURE: The recipient server did not accept our requests to connect. Learn more at http://mail.google.com/support/bin/answer.py?answer=7720
[inbound.mydomain.org.emailmx.com. (0): Connection refused]

Any clues?
