I haven't really used any of them directly, but I've heard good things about 
CloudMark, MXLogic, and Postini.  Postini I am most familiar with, it has a 
web interface for management of user accounts and settings, and you list them 
as your primary MX, then they pass along e-mail to your servers once it's scanned.

You say that your system can't keep up with SpamAssassin -- another thing to 
consider is upgrading the hardware.  Depending on how many user accounts you 
have, the pricing may be similar over a year or two, possibly even cheaper. 
You can get a pretty powerful machine, in rackmount trim, for around $1200 
these days.

For the record, for our 7 people we have a dual core 3.4GHz P4 system with 4GB 
of RAM and it performs well.  We recently took it from 2GB to 4GB because 2GB 
just wasn't enough.  SpamAssassin really uses the RAM when you really get hit 
with a lot of spam.  Our mail system currently says 3.4GB free (1.8GB 
completely unused), so it's really only during the spikes that we need the 
extra RAM.  But this system does little other than e-mail.
