Record MX on different domain

Hi,
my domain is localdomain and my company website is on internetdomain.it
On our public DNS server we set:
1 Record A: exchange.internetdomain.it >> our public internet IP address
1 Record MX(10): exchange.internetdomain.it
We receive mail directly to our exchange server and all goes ok, but from my
internal server,
if I ping exchange.internetdomain.it, I receive the firewall IP.

This configuration can cause problems?
How can I set my local DNS server to resolve correctly
exchange.internetdomain.it (exchange.internetdomain.it >> myserver.local)

I've tryed to add another zone to my DNS server, and add the
exchange.internetdomain.it records, but if
I do that, searching for www.internetdomain.it and all others request gives
me errors (because is searching locally not on the internet).

Thanks

I hope it's localdomain.something - and not just localdomain. Single-label
domains will cause AD problems.

That's fine -

Right....that's normal. That's what it points to in DNS.

No, it shouldn't.

Why would you need to? Why would anyone in the office need to use
exchange.internetdomain.it?

Correct, because you told it to do that.

What's the reason you need to do this? If you have some compelling reason,
you might post in a DNS group - this isn't an Exchange issue.
