Filtering Spamming

[Baltazar Quinterno]

Can anyone give me some tips for filtering incomming mails
from certain hosts or e-mails adresses.

Im running Qmail+tcpserver,

does anyone have a script from deleting messages from queue, following 
some match, for cleaning spamm from spool.

Thanks a lot.
