FWIW, you have some unnecessary information in your DNS.

You have 2 MX entries:

[egreshko@gangster tmp]$ host -t mx gc-site.hopto.org
gc-site.hopto.org mail is handled by 5 mail.gc-site.hopto.org.
gc-site.hopto.org mail is handled by 10 gc-site.hopto.org.

but....

[egreshko@gangster tmp]$ host mail.gc-site.hopto.org
mail.gc-site.hopto.org has address 67.34.177.240

and

[egreshko@gangster tmp]$ host gc-site.hopto.org
gc-site.hopto.org has address 67.34.177.240

Are the same.....

So, if my system has mail for you and your system is down or not
reachable it will try mail.gc-site.hopto.org (fail) and
gc-site.hopto.org (still fail becuase it is the same).....which is
unnecessary.

Not sure how many IPs you have or if they're static, but both mail.gc-site.hopto.org and gc-site.hopto.org both point to the same IP so you probably have 1 external IP.
