RE: [Exchange] Executive Email Solutions

[Michael B. Smith]

I use a very aggressive anti-spam solution. ModusGate by Vircom.

But my oldest address has been around since 1982. It probably gets a couple 
thousand spam a day, compared to one or two good emails. My other two primary 
addresses get hundreds of spam a day with perhaps a hundred real messages. 
ModusGate does occasionally get false positives and I don't always catch them. 
But I train as well as I can. That is the cost of doing business these days... 
But I think it does a hell of a job.

And no, I don't get anything from Vircom. I've been using them as a satisfied 
customer since 2002.

Does your spam solution allow the user to train it on what is spam vs.
ham? If it does, has the exec or admin done that? Also if it does, and he 
and/or his assistant have done that training, can you take a look at the 
training database to see if it's working within specified parameters?

The Bayesian databases that I've used require a minimum of 200 emails mark for 
each kind (spam and ham) and sometimes don't work well if they get too far out 
of balance (that is, say 201 ham vs. 10k spam).

Training a Bayesian database is always an ongoing routine. Stop the training, 
and eventually the spammers will win.

Another thought - if the organization doesn't have contacts outside of your 
country, can your spam solution block by country source, using IP ranges? Not a 
usable solution of your organization has cross-border contacts, though.
