Urgent DNS Issue


I host my own DNS on my web server, never got around to getting second DNS host which is another story in itself LOL.

Yesterday I made some changes to a zone file for my personal website and added a site in apache2 (blog.example.com). I have since taken out the extra site and removed it from my DNS entries. The problem I have now is my domain just now came back today but now my mail which I run thru google is not sending or receiving.

Does this db file look correct to you guys and do you have any suggestions? Are the refresh, retry etc too short?

Note I just added the ns1/2.slicehost.net today to get my www.example.com site backup because ns1/2.example.com is not working and now another site I host is all jacked up as well, no mail, no website

Also when I use google's free tools to look up things I am getting this error in regards to my MX records.

Try named-checkzone ... I don't think the hostmaster email address is supposed to have an '@' though

zone checked out ok must like the @ sign. I have narrowed it down to a propigation issue. I have a friend who has not ever gone to the website and he was able to hit it. I ran this command to see how much time I have left before it expires:

dig -t ns example.com

I have 22649 seconds (just over 6 hours) to go woot woot.

I fixed this issue this way.

There was an issue with the way my NS servers (ns1.example.com and ns2.example.com were propagating. So I added ns3.example.com and ns4.example.com and changed them on my server as well. Restarted bind and then deleted ns1/2 and it is working now.
