The problem with natting in my case is that I have two mail servers in house
at this time and try setting up nat for two different servers with the same
ports, (110, 143 and 25) but different IP addresses.  The alias idea is two
ip addresses on the WAN that is then natted to the two different servers
which works now.

It would work just fine if you knew what it was for.  RTFM

The name is probably a bit misleading, but it's under the Firewall
section, hence Firewall aliases, not IP aliases.

You should never set up ifconfig aliases.  Server NAT would work fine
for what you're trying to do.
