Exactly my understanding. Further, it's my understanding that reverse checks done by other mail servers
not many mailservers do that, and such servers will have tons of problems rejecting legit mail
on mail that we send looks at the sender domain in the envelope of the email
ok, env @sender.domain must have A and/or MX record, period. it might have SPF records, but SPF carries insignificant or no weight now.
and the IP address of the machine sending the email (also in the envelope) then does a reverse lookup on the IP to see if it matches the domain.
wow. these people are nuts. They will reject all outbound-relay mail gateways whose HELO hostname, PTR hostname are not any anyway related to the many env sender.domains that outbound relay delivers, eg, IMGate-type machines, ISP outbound gateways.
I have never seen such a reject from any of my IMGate sites, or on the IMGate list.
By default, Imail writes the virtual domain to the email envelope
sure, IMail isn't going to re-write the [EMAIL PROTECTED] as sumbitted by the Imail user.
and since we have multiple virtual domains, the IP never reverses to that domain.
There is no problem with your setup, the problem is with the idiocy on the other end.
