Postini...  Let them handle it on their servers.  You can detect harvest
attacks, which they auto block the offending IPs, virus attacks etc.
Again all on their servers.  Nothing hits yours unless you push it down.
You can see which viruses are coming in and from who etc etc etc...

Subject: [exchangelist] Spam and A/V appliances.

Hello all. I'm looking for input on an SMTP e-mail appliances for
spam/content filtering and antivirus.  I prefer an appliance over
software I run on a server, but I'll also accept input for software
based products.

My exchange front end does nothing but SMTP transport work, and A/V
scanning. It has no stores on it.  My current spam product runs on the
back end servers, because it uses SMTP Event Sink to pick off spam.
This means I have to let spam come to the back end server, causes
unnecessary load.  I want something to put all the way in front to
reduce these loads.

Two of the popular names in appliances are Ironmail and Barracuda, so
I'm obviously interested in those.  I'm also looking at St. Bernanrds
ePrism, as we have their iPrism already.

One of my absolute requirements is how spam is managed.  I must have
ability for end users to manage their spam and it's settings.  In
conjunction with global black/white lists Users must have the ability to
maintain their own (through web interface, directly in outlook,
whatever).  The user must be able to view the items in their quarantine.
The key to his is the USER has some control.  I cannot utilize a device
where an admin has to go digging through quarantines for legit mail, or
where an admin has to approve a mail from being released from the

Beyond that, I'm somewhat flexible.  I'll continue to use my Exchange
front end A/V, but I want some decent A/V functionality in the appliance
to reduce some scan load.

Based on this, can those of you who have used any of the boxes I've
mentioned, and others, provide input on if they would meet my
requirements, and what your experiences have been.
