It's perfectly normal for there to be MX and A records for names under
the COM domain. chrysler.com has A and MX records, for instance.

If you're having a mail delivery problem that is solved by
reloading/restarting your nameserver, then it's probably a delegation
problem of some sort. These are becoming quite common these days. If you
give specifics about the domains you're having problems with, then maybe
it might be possible to give a specific answer as to why it is happening.
Unfortunately, the fix usually requires the owners of the other domains
to fix them, and unless you have a lot of leverage with them, it may not
be easy to get them to do that (especially if they are clueless and don't
even understand what the problem is).
