Was not disputing you Len. Just wanted all the bases covered so there
weren't any surprises

If [EMAIL PROTECTED] is on machine "A" sending a message to
[EMAIL PROTECTED] on machine "B" it will never get there if using the home
IMail server as their outbound MTA. IMail doesn't send all mail through
the gateway. It only send "remote" mail through the gateway and since
example.com is defined on both servers you will get an envelope rejection
right after the RCPT TO unless the peer list is active.
ok, peering is active, but only works for peered domain users sending from
Imail-A to Imail-B, which is typically (much) less that 10% of total
traffic. The vast majority of traffic is inbound via MX, and IMGate would
relay that traffic precisely to the user's mailbox server, so peering
wouldn't kick in.
Typically a peering system does it to distribute the mailbox load. IMGate
also removes tons of other work and abuse from the Imail boxes, as well as
pre-routing MX traffic so the peers don't have to probe the peers.
