We are subjected to Postini through corporate and since it's rollout, we've had nothing but trouble with NDRs and weird message limit things. I used US Internet's Securence product for 3 years, by far the cheapest solution, very few false positives and after it's learning curve of about a week we stopped spam down to about 3 to 4 messages a week from 3000 a day that got through to 150 users. In addition all email viruses stopped showing up period. I can't recommend them enough. Great customer service too. I was never on hold for more than few minutes, any time of day. That's my preference for spam and virus.
