I don't think you would need a "mail.domain.com" entry in the HOSTS file.

Thanks Dan
Both servers have their primary DNS set to the internal dns server.
No secondary is set on either server since the inernal dns does forwarding to
the ISP's server if external resolution is needed.
While the zones were setup I was able to do just that. nslookup, tracert
resolved the internal IP's wihtout fail. Each server could ping and telnet to the
other by IP, domain.com and mail.domain.com
The A and MX records are right for internal use. They are identical to
external except the IP's.
Gate Host is blank in Imail administrator.
The Firewall log for ISA indicates no blocking of traffic from Exch TO
Imail...just FYI.
I don't get it. The only diffirences between the HOSTS and the zones I tested
was the "domain.com". Another Imail poster explained that the HOSTS file would have to
have the "mail.domain.com" and "domain.com" entries. However, in the dns zone I know
of know way to enter the "domain.com" if it doesn't simply get that fomr the zone name
itself (domain.com.dns). I am not the brightest star in the sky by no means, but I am
missing something somewhere in all this.

If you set up internal DNS but couldn't resolve the IPs then the servers
weren't using your internal DNS server. If you set up the internal DNS with correct A
and MX records, set the mail servers to use the internal DNS, and don't have Exchange
or Imail set up to use a gateway to deliver the mail for them then it simply has to
work.
If I were doing this I'd set up the internal DNS server and set my workstation
to use it. Then I'd use dig or nslookup or ping and telnet to query it and make sure
the MX and A records resolve to the internal IPs and that I connect to the proper
servers. Then I'd change one mail server at a time and make sure they can resolve the
IPs using ping and telnet. I think Imail has a separate setting from the OS setting
for DNS so make sure that's correct also.

creating the internal DNS zones for these domains (split DNS). They were identical to
my external zones except using internal IP's and all records had their matched PTR's.
Afterwards neither server would move mail to the other. Imail's log showed same errors
as always and Exchange indicated could not resolve DNS name. I am back to using HOSTS
files for now till I get it figured out.
