Opps, didn't I tell you to replace mydomain.com with whatever your domain name is? Sorry.

Make sure you can see your domains' MX records through DNS - not just that they are in the configuration files but that when you ask for them via nslookup, DNS gives you the information.

Also look up any of the domains that have failed to have email sent to them - this may give you a clue on what to do.

A good site with FAQs on DNS is:
Mr. DNS

off course i changed the "mydomainname" to my actual domain name, i just gave that to u for security reasons.

i am able to nslookup to hotmail, yahoo and the rest from my mailserver.

i really doubt if the problem is dns related.

I have descided to reinstall my mail software, in the course of doing so, i might loose my user mailboxes and other configuration files in the process. But i have backup to a certain extent.
What i need help on now is on performing a restore process. I have never done that. And also to hope that theproblem with backing up of my mailserver has to do with the mailservers inherent problem. Otherwise, a restore process may not work.

I wish we could chat, soo this conversation could flow at a faster rate.

I really need to get this server back up my tommorrow.

You wrote: and that was all i saw. i didnt see "mydomain" at the end of it.
When I questioned it you wrote that you changed it to your domain.

If you asked for your domain MX records from nslookup, you should have gotten back a response that would have had the same type of output as the digex.net did (just different domain and IPs and hostnames).

I asked you to test something - if you don't know then send me an email - I opened an old email server to see if it will show anything on this side when you try to connect - but I will have to shut it off within a half hour to insure all the spammers don't start using it again (I already saw three messages hit it from spam sites - unbelievable!)

Just to update - helping with mail problem - use this site to check your mail servers
