I've heard great things about IronPort. In fact, I talked to a sales
rep about 2 months ago, and he was very cool.
The problem is price. They're incredible...* if * you can afford them.
For those of you who submit to spamcop, you'll see that ironport is
all over those reports.

UVa. just retired its greylisting service and has opted instead to
use a new spam management system called IronPort Protection. Testing
has shown that it is much better at reducing spam and generates
almost no false positives.
