Need a spam killer for the Mail app

Question

I am very disappointe hwo the Mail app handles spams so I would like to hear suggestions
on a Spam Killer app that you have good experience with
Junk It boast to tracks messages and keeps score of who offends you the most.
That seems to me a nice feature
Other features I would like:
-spam mails should bounce back to the spammer
-a log who are those spammers and to send complaint automatically the the internet provider
What other features are useful ?

Answer 1

I've found SpamSieve to be very effective in catching spam.
I would also like that the mails bounce back to the spammer
Please, never bounce spam. Most spam has forged 'From' addresses so all you are doing is sending yet more spam to totally innocent people (who are probably already getting a lot of bounces because of this) and making a bad situation worse. Even if the 'From' address is genuine, I very much doubt any spammer is going to remove your address from a huge list  (they certainly would get a lot of bounces from actually dead addresses) - and in any case they can probably tell it's not a genuine bounce easily enough, so now you've just confirmed that your address works. Don't bounce it - just delete and forget.
I need a log who are those spammers and to send complaint automatically the the internet provider
This is the same thing - most spam has forged 'From' addresses using innocent parties' addresses so all you are doing is making things worse for them when they are probably already getting a lot of bounced spam.
