We are an ISP and currently use PureMessage from Sophos, its and anti spam
and antivirus solution its proved to be very effective and allows each users
to also fine tune his or her spam filtering rules. We are also in the
process of deploying an Ironport at some of the major internet exchange
points as our primary MX like LINX and SAIX. One thing to note about the
Ironport appliance is that its is expensive compared to most spam filtering
solutions.
