I've just this weekend re-installed IMGateAV from a P75/32 megs as my
test bed to a P300/64 megs for production. It works fine, including
the automated daily/weekly virus database updates from
Kaspersky. The virus msgs are quarantined and Virus Alert messages
are sent to sender and recipient(s) in text files that can be
translated to other languages.
The Kaspersky Anti-Virus Daemon for FreeBSD or Linux is $560 per year
for unlimited domains and mailboxes. At any price, I think Kasperksy
has an excellent product, and for $560, it's unbeatable for
daemon/service type of product. Everything else in IMGateAV is open
source, free software. Of course, you can use other SMTP "name
brand" scanners with IMGateAV for 10 or 20 times the Kaspersky price.
I position IMGateAV (btw, it's not all tied to Imail) for larger
volume messages flows, and where there is more than one Imail
box. Also, the multi-box solution is necessarily a more
defensive/protective Internet buffer for the backend mailbox servers
while offering more mail routing flexibility and redundance. We have
a 4-box setup here (2 IMGate MX's, then IMGateAV, and finally Imail.
Actually, 5 boxes if you include the dedicated Listar list
server). IMGate's header and body filtering is catching a lot of
viruses (Snowhite recently) before they even get to IMGateAV.
I've put together a big IMGateAV installation script (for FreeBSD)
that saves a ton of time but it still needs some work. It should be
in good shape in few days when I will also have more production
experience with the box. Note that I'm not in any way a pioneer with
IMGateAV technically. It's been around for a couple of years.
For the smaller volumes and for colo's where a 2nd colo box @
$300/month is not
reasonable, I think Scott's Declude is a great solution.
As for IMGate, anybody can install IMGateAV themselves, or I can
install it for what I'm told are reasonable rates.
