I didn't mean to imply that you were trying to restrict other peoples 
email - just that I see more and more people putting restriction on the 
email they will accepet.
  I had trouble at work this week with a company that blaclisted our 
mail server without notice or explanation - someone who runs a mailing 
list on this server couldn't recieve any mail from us and it took ages 
to get the block removed ...

This sort of thing is becomming more common - common enough to see it as 
part of a general trend - it is that trend that I refer to.

   There is something about those of us who are 'into security' that is 
being taken advantage of by corporations who want to make the internet a 
more controlled environment.

I haven't set up spamassasin - but I do get mail on a system that has it
I'm very happy with it (although I don't get enough spam to judge 
really) - what I like is that I still get the spams - but with altered 
subject line so I can filter them myself.
