    I have had trouble with SSH / FTP hackers trying brute force attacks but that was easily solved with Denyhost.

    Now I have a more tricky attack,
    A hacker trying every combination of mail adresse on one of the domaine I host.
    Each attempt comes from a different server

    After a while I noticed the servers are indeed cyclic so there is a finite number of servers to ban from connecting to my SMTP.

    Is there an easy way to ban a an URL from connecting to my SMTP ?
