I'm seeing a reduction in rejected messages with no reduction in
delivered mail.

Hi Richard -
One method is to put ORF in front of your IMail box and via its
recipients blacklist feature refuse
I have a question about these boxes that
go in front of Declude, be they IMGATE or ORF or whatever.

correct?
For ORF that is correct - at least the way I use it -

There are two things that a gateway will do for you; address validation
and pre-scanning the most obvious spam in order to reduce the load on
an IMail/Declude setup.
Address validation is an absolute requirement if you add a gateway, but

FWIW, Matt, this has changed recently. It makes
little difference to you, but I thought this was worth pointing out. The
whatsnew.txt for IMail 8.20 and up says that it has the ability to bind the
SMTPD to specific IP addresses. Previously, it bound to all
addresses.

ORF plugs-into MS SMTP. I have unfortunately found that MS SMTP
doesn't appear to handle rejecting oversized attachments when sent with
HELO (not EHLO). When messages don't get rejected properly, they are
sent over and over again until they time out. I have a 20

Address validation is an absolute necessity unless you either want to
spend extra money on multiple scanning boxes and/or suffer outages due
to pure load. As you add on more domains, the load from dictionary
attacks on non-validated addresses will bury you. If these bogus

Hi Goran,
Another
follow on question. In either the

the
domains? So for some you would do the address validation and for others
you

Sure. What you have now is wide open - so the

Bill,
The issue is that MS SMTP has a habit of sending back a 552 error while
the DATA transfer is still going on, and the sending server doesn't
notice the error and then just requeues the message. I did some
extensive research into this behavior and found that this was in fact
what was
If you are running IMail and are using the
registry, as opposed to an external database or windows user base, IPlus Info
Browser will create this list for you. It can be scheduled to run
periodically so your list stays up to date. You can download a demo at http://www.martekware.com/ipb.
Sandy,
FYI, restarting ORF doesn't affect MS SMTP as far as I can tell, and as
long as you configure MS SMTP to accept all E-mail, all that a restart
of ORF will do is cause a moment of un-validated E-mail which should
get deleted by Declude as spam if it came from a dictionary attack.
