This is true, as far as you go over standard compliance checks and unserstand 
standard violating (absuive) mail as "spam" in any case - it (not at least) 
depends from what you DEFINE as "Spam" (or abusive Email).

Each working internet mails ystem (working means: is able to send email to the 
very most of recievers) has to filter out some kind of mail traffic - at least 
proven hardly abusive or what the majority of mail server admins understands 
as "abusive" (otherwise your own users mails get blocked from others). This 
means that you WILL block emails from regular users too, unable to send a 
"correct" email.


hth a bit,
