Incoming Email Problems

I have many sites with their own IP addresses and most of the domains email are forwarded to one domain which has an email account but the server is not getting any of the emails sent to any domain, nor are they bouncing back.

Where do I begin to trace the problem?

Thanks

 

Thanks, yes forgot to mention there is no sign of the incoming mail in those reports

 

All mail from every domain is cued due to a time out problem and no incoming mail is recorded

Thanks

 

No everything looks ok I had checked there

I just checked /http://www.mtgsy.net/dns/utilities.php

Getting MX records for 'my-domain.com'

There are 01 MX records (Mail servers) for the domain 'my-domain.com'

Testing each mail server in the list using the address mailx@my-domain.com
Testing .my-domain.com, preference = 0
Checking to see if .my-domain.com is in any of the popular RBL's - PASSED - Not found in any RBL's
Trying to connect to .my-domain.com
*CONNECTION FAILED*
Could not connect to .my-domain.com

 

Thanks

Using "Address Literal" - (Does my mail server accept incoming emails addressed to my IP address?)

It returned "Failed submitting request" but no details

Still working on this and not getting anywhere, no help from hosting company yet either.
