Re:OK so when exactly? (Score 1)

I've been using Spamdyke for two weeks now and it rocks.

I love the SMTP Auth and extra spam filters. (Spamdyke saved me from moving to postfix yet.)

From the website:

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!

Netqmail + Spamdyke and no more patching.
