Tom, Messagelabs was right around $4500/yr for the services we've contracted for - antivirus, antispam and antiporn. The first two work well. The last one is worthless, IMHO. The users are happy with the spam levels we're seeing. Messagelabs also offers an outbound scanning service (comes with every account) and has not been reliable at all. We're getting sporadic 553 errors as well as bounces because one or more of their servers have found their way into SPEWS.ORG's lists.
At this point, the appeal of SpamAssasin isn't lost on me. When we went with messagelabs, the goal was less administration which has turned out to be a myth with Messagelabs. I've used the Postfix in the past and will take a look at SpamAssasin again. Thanks for the reply!
