David,
I've said it dozens of times here in the forum, in many threads. Here is the
short answer:
To use anything other than the true hostname for the domain running on the
Primary IP address, one must add an entry in the HOSTS file. See manual
(V6), pg 26, Checking Configuration of the Primary Mail Host.
For any other IPs and domains, you do not need anything special, as far as
IMail is concerned.
Why? Basically it has to do with 'name resolution' within IMail and the
local machine. And it is likely that 'domain.com' has a different A record
than 'mail.domain.com' and getting that from DNS would cause IMail to try to
deliver to the 'wrong' host.
