but the problem addressed with it is a common problem as soon as you
have a mail appliance infront of your exim/postfix/whatever setup.

In some cases there is no choice. You won't find an open source virus
scanner that beats or nearly reaches the same detection rates and comes
with heuristic that the world leaders Kaspersky and Symantec do. And
similar, you don't find an out-of-the-box spamfilter that has zero false
positives and a high detection rate for ISPs like eXpurgate (thats the
name of our solution). If you have ever worked with SpamAssassin, you
would know that it is no possible to use it with a good detection rate
without of much regular manual work and configuration for 500.000
messages and more a day per mx server.
I don't want to discuss open and closed source since we use both of it
whichever does its job better.
