Spamdyke
Aus CrazyLinux
A drop-in connection-time spam filter for qmail
spamdyke is a filter for monitoring and intercepting SMTP connections between a remote host and a qmail server. Spam is blocked while the remote server (spammer) is still connected; no additional processing or storage is needed.
In addition to all of its anti-spam filters, spamdyke also includes a number of features to enhance qmail.
Best of all, using spamdyke does not require patching or recompiling qmail!
