    Our Postini service is billed per mailbox used. Postini in front (McAfee); 
Instagate at the local firewall/gateway (Sophos); and Norton on the desktops = 
3 libraries before a virus can see light of day. SPAM is virtually eliminated 
at Postini and the remaining trickle is usually caught in the Instagate 
(SpamAssassin.) No end-user access to the Instagate quarantine but the few 
remaining after Postini is easy to deal with (looking for false positives.) I 
do that about once every two weeks or so... The Instagate is awesome LINUX box 
that just sits there and hums along. They're also now offering anti-spyware at 
the gateway module; Paladin. Nice.

I was wondering if anyone could ask a question on Postini, or MessageLabs.  
I've been previously informed that you have to license "all or none".  Meaning, 
if I have 1300 users, they get payment for 1300 seats.  You can't selectively 
choose what users run through the service.  This is correct?

I have to agree with Doug, Postini works great and is more cost effective in a 
small to midsize environment.

I think I should add a qualifier to my earlier statement. If you don't have 
many users then something like postini maybe the way to go (we actually use it 
where I work now...about 100 users), but at my previous position it made much 
more sense to buy a $3000 barracuda for 6000 users than $4 x 12months x 6000 
users. 

 

The $3000 model that we had processes between 90,000 and 120,000 messages a day 
with no problems. Even the threshold set to the default of 3 out of 10, and 
Bayesian filtering not even used, 78% of our messages dropped before hitting 
the exchange server. Talk about a cheap way to cut load and increase life on a 
mail server.

 

 

But again, that would have been a little expensive for 100 users

I would almost bet the barracuda will cost you less in time AND labor than 
others. And it works great!!! Check it out. http://www.barracudanetworks.com
