EXIM ACLs for dictionnary attacks
++ ACL Rule Replacement for Exim 4-24.x + anti dictionnary attack rules ++
- Added anti dictionnary attack rules - Have you ever seen spammers attempting to send huge amounts of messages to jane@domain.com, peter@domain.com, ashley@domain.com etc., when in fact neither of these users exists? And if they do exist these users are being dictionnary style spam bombed? These rules will drop the connection and attempt to ban the spammer from connecting for a period of time even when they try to reconnect they will be immediately dropped. God they will be annoyed!!! <SMILE>. In your /var/log/exim_mainlog you will see an entry like Dictionnary attack (x failed probes). Dropping connection!:
