I never seen this fail and everybody uses it all the time to short-circuit DNS resolution. Anyway, you didn't answer my question about what happens when you ping, traceroute, telnet:25 from each machine to the other's IP (not its hostname). > However, no other entries for those machines. What should my internal > DNS look like in order to resolve my two external mx/A records. If you use DNS to resolve, it's stupid simple. You set up the MX records for each domain to point to MX hostnames, and then put in A records in each exchange or imail zone: in the exdomain.com zone: mx.exdomain.com. A ip.ad.re.ss in the imdomain.com. zone: mx.imdomain.com. A ip.ad.re.ss But in hosts file, the same thing: ip.ad.re.ss mx.exdomain.com ip.ad.re.ss mx.imdomain.com The hosts above asssumes Imail will find the above mx hostnames in DNS, then resolve them to A records in hosts file. If you don't put MX records in DNS, Imail will try to send to the A record for @recipient.domain, so you would need to add A records to hosts file: ip.ad.re.ss exdomain.com ip.ad.re.ss imdomain.com where all the above IP addresses are the IPs of the Imail and Exchange boxes.
