Objective site to run spamcheck against?

[Tuc at T-B-O-H.NET]

Hi,

        An inordinate amount of people are telling me I'm
ending up in spam folders, so I wondered if there was 
some "objective" site where I might be able to run a 
message through and have it score an email. I realize this
could also be used by spammers to check about getting past
the filters, so I'm thinking maybe there isn't. I can't
run it against my own systems since they like me too much. :)

                Thanks, Tuc/TBOH
