 What have you thought of IMGATE so far?  How effective is it=20
 compared to your previous solution?

So far, I am only using IMGate as an anti-spam gateway for my secondary
(Imail) mail server. I am slowly working on replacing that box =
altogether,
and will eventually put an IMGate/Postfix box in front of my main mail
server as well, as soon as I am comfortable enough with knowing how to =
run

snip

I'll probably also integrate my SortMonster/MessageSniffer filter into
spamassassin eventually as well. That is by far my most effective filter =
on
the IMail machine. Long-term, I will eventually scrap IMail altogether, =
and
just run a pure Postfix box behind the IMgate box. I have a LONG way to =
go
before I will feel comfortable enough to do that though.

Postfix behind IMGate?  IMGate is Postfix.  This is not Windo$, you don't need 
the redundancy.
Now, many will run Spamassassin/virus filtering on a second box, and that would 
not need Postfix.  Now, for replacing IMail, then the second box could be 
Courier/Cyrous per Keith's example, and Postfix would not be needed on that box 
either.
I've been happily running IMGate(Postfix) in front of my IMail/Exchange boxes 
for several years now! :-)  I'm getting ready to start setting up a replacement 
for IMail, probably based on Courier.

When it comes to imail and protecting against dictionary attacks, you have 
only imail and blackice that I know of.

Imail add-ons (declkude or our own , mxGuard) can not protect against them 
because Imail takes care of all the smtp communications - then hands the 
message off to the add-on.

Postfix is always a good choice, no matter what you are trying to do.

 You might look at mxguard.  They have a SPAM and Virus solution for Imail
 that is very reasonable.  Not very customizable however.  Are you running
 Blackice on your Imail server?

 Aaron,

 Blackice takes care of the dictionary attacks for us and it uses very 
 little
 in the way of resources.

 I'm looking for a spam solution.  I'm running ASSP but it makes a lot of
 mistakes.  Declude is insanely expensive and I'm not willing to spend that
 kind of money on their solution.

 I was wondering how IMGATE was doing with your spam?  Do you have many 
 false
 positives or missed spasm getting through?

 My previous solution was no solution at all :-)

 IMail 7 has no way of preventing massive distributed dictionary
 attacks, and our IMail box was being brought down with frightening
 regularity (this is a 3ghz server, mind you).  A little 233mhz
 Pentium-MMX running Linux and IMGate sitting as a proxy between the
 outside world and IMail was enough to stave it off.  I've since added
 a second IMGate box largely as a failover, but also to take some load
 off.

 I'm very impressed with IMGate/Postfix, and in the long run, we'll
 probably abandon Windows-based email solutions entirely, and use one
 of the boxes as the mail server.
