Re: Virtual SMTP - Queue

Tech-Archive recommends: Fix windows errors by optimizing your registry

iii. I've checked the set up for the Smart host and on the
(delivery/advanced) tab there is an i.p. address , it's the i.p
address of our Firewall.
(64.8.218.12) and not our exchange address.

Is your firewall an SMTP proxy?

I've selected the "Attempt direct delivery.." check box but still the
same.

Please read my previous n/g posts on this area.

If you want to do direct delivery, ensure that your mailserver can
resolve remote MXs via DNS (UDP/TCP 53) and connect to them via SMTP
(TCP 25). Microsoft's SMTPDIAG is helpful. You also must pass the
PTR-EHLO-A roundtrip test I refer to frequently.

If you expect to use 64.8.218.12 as your smarthost instead of your
mailserver doing direct, [a] it should be in square brackets
[64.8.218.12]; [b] _it_ must be able to fulfill all of the
requirements above.
