They are perfectly happy with the arrangement:-)

I'm not involved in any criminal behaviour. If they want to waste their 
efforts monitoring friendly foreign countries' citizens.... Not forgetting 
the scandal when they're caught.

Nah. That's what MTAs do. But, it costs bandwidth and time to do.

The average desktop system's not running software with the nous to do the job 
properly, and isn't connected enough hours to handle difficult mail anyway.

Tut tut.

I check my logs from time to time. I see lots of mail to my spambait addresses 
being plonked because it comes from  blocked address. I've not noticed any 
legit mail getting dropped.

If you want to send me mail, you gotta meet my rules. These include approval 
by my blacklist providers.

Also you gotta pass my header checks. No funny East-asian character sets, we 
can't read them. I'll drop Russian and Greek when someone tries those.

Then Spamassassin gets a look. Everything to the spambait addresses that gets 
here is processed by spamassassing as known spam.
