Dudes, you are all so awsome. Actually webmin had set it up so that the file was /etc/bind/mytestdomain.com.hosts and the record was setup to:
Code:
mail.mytestdomain.com. CNAME mytestdomain.com
I changed that record to
Code:
mail.mytestdomain.com. A 192.168.10.53
and all worked well.
I really appreciate your straight-up answers.

PS: I think this DNS thing is getting a whole lot clearer now. I'm going to set it up by hand next time. Practice makes perfect.
