I'm pretty sure this is only happening at one company that is running their
own DNS server. I can send email to them, but when they reply they get a
"user unknown" error.

The domain name in question is with a current ip address
The DNS server that is having trouble is returning for
this was the ip address from our old isp & is at least a couple of months
out of date.

Anyway, I've alerted the people responsible for that DNS server & they are
looking into it.

My question is more of a general nature. How can I check my own DNS server &
make sure that I don't have any bogus info cached?
