Trend Micro spam filter

I finally had a chance to install Trend Micro's mail scanning
component on our SBS2003 and was pleasantly surprised at how effective the
spam filtering seems to be. How many of you are using that as your only spam
filter? Any other comments? Until now, when a client requests spam
filtering, we've been using a paid outside vendor for spam filtering before
it even reaches the Exchange server. We've been using Symantec Mail Security
on the inside, but as I've mentioned I've been looking at competitors
because I'm just too annoyed with Symantec's licensing procedures and the
software isn't so good that I need to stick with it at all costs. I do have
one guy paying $300-$400/month for spam filtering and "business continuity"
but he's starting to think the bill is too high (it was his idea originally)
and I'm thinking that Trend Micro C/S/M may be the way to go for him. (His
Symantec license expires in the next month or so.)
