use commercial spam filtering service?

[Bryan O'Neal]

I pay ~$500/ year to commercially filter my companies email.  Without it
some of my users would get upwards of a thousand spam emails a day, and
as a whole our mail server was getting hit with 20-30K spam messages a
day.  With it on we get about 3-5 pieces of spam a week that get
delivered to users accounts and maybe 20 a day that hit our server and
go no where.  It is pretty much the only spam filtering we need and is
well worth the money IMHO.  On a side note, we very, very rarely have
problems with false positives, however we have had to tweak their
setting on some of the forwarded email accounts from extremely spam
prone mail server (like the state bar associations mail servers)

Some of my FreeBSD and Linux customers have own mail servers, but use 
third party companies to be the MX for their domains.

Do anyone of you use a commercial spam filtering service?

Please share your thoughts about it.

Do you use it to supplement other spam filtering?

Do you just use it as the main MX and it then relays legitimate email on

to your real mail server?

How did you decide it is worth its value?

Do you have any research to show how beneficial it is for you?

Any significant lost mail or significant delays or other problems?

Do you also pay to have your outbound mail relayed through their
gateways 
too?

As you can see I am researching this :) If you know of any good webpages

or news articles that compare different companies, please let me know. 
(This seems like something that InfoWorld reviewed ... I am searching
...)
