Re: Blocking mail from bad places
1) You send bounces from spammers to innocent people, whose addresses have been forged.
2) Even if you modified the return address, so the bounce returns to the zombie, it does not make sense. Bots dont listen.
Looks like you are adding to the noise and chance is good you are finding youself in a blacklist.
3) You are dropping valid emails.
It might make more sense telling your friends not to send emails to port 25 but to port 26 if they want to get in. The spammers dont know how to switch to port 26. They will knock on the door once and go away.
Another means would be switching to uucp. I have not seen any spam on our little uucp network yet.
