MX Record on Linux 9 Question

[tnaves at linkwest.net]

I set up a dns server on a Linux 9 box using the DNS Tool.  When I add an
MX record it creats it in a weied way.
You cannot just add an mx record, you have to edit the properties of an
existing host to ad the mx record.  Having used the dns tool, I can't add
the mx record by editing the zone file. 

The dns tool makes it like this:

mail	IN	MX	10	mail.mydomain.com 	#mail being the
name of my mail host 

instead of like this:


	IN	MX	10	mail.mydomain.com

Has anyone done this using the DNS tool?  Do you have any suggestions?
Would the above render the mx record unusable?
