It is, indeed, not possible. There is proprietary communication between
Imail peers.

The acmereservation.com reply 'bot just has to spoof-a-header "MAIL FROM:
[EMAIL PROTECTED]". Consult you local spammer. This is so easy it's not
even interesting.
If acmereservation.com had Imail, they could spoof by creating a virtual
host @AcmeGolf.com and create a [EMAIL PROTECTED] account and send all
their responses out throught that account, so the MAIL FROM: would be as
desired. But DNS would be set up so
acmegolf.com. MX 10 smtp.acmegolf.com.
acmegolf.Com. A ip.ad.re.ss
So paunchy duffers responding to the reservation confirmation from the
spoofed @AcmeGolf.com would have their mail go to the the real ip of
acmegolf.com and not the MX of spoofer acmereservation.com.
You can also do the spoofing with postfix in the http://IMGate.MEIway.com
project (aka Acme Corp. Inc. Fool-Proof Anti-Spam Kit).
The @acmereservation.com mail server behind the firewall sends all mail as
normal
"Mail From: [EMAIL PROTECTED]"
... to the IMGate box as a "bastion mail server" outside of the firewall,
which has a "rewrite" facility so that "@acmereservation.com" gets
rewritten as "@acmegolf.com". Pretty wily, huh?
Plus, IMGate can provide all its usual defenses for the incoming mail, as
the primary MX for acmereservation.com and then relay the mail thru the
firewall (which only accepts incoming mail only from the IMGate ip address,
hardening their defenses even more than now) to @the acmereservation.com
mailhost.
(man, this had nothing imaginable to do with peer servers)
