Don, your answer is technically correct, but likely to confuse the poster
more.  If he is running mail servers, hide nat would be worthless, since the
obvious need for connecting to the mail servers from the outside.  Static
nat would obviously be required, but if you think about the IP routing, with
static nat you must map a legal host IP to an internal host private IP. 
You cannot point one address to many, without some kind of intelligent
decision about to which to send the packet.  It would require some
load balancing software.

If I have multiple mail servers on the internal network, can they all share the same NAT’d external address?

 

This is NT4, 4.1 SP5.
