Spamdyke, A drop-in connection-time spam filter for qmail

nospam@example.com (NickNack) — Sat, 11 Aug 2007 17:37:09 +0700

Spamdyke is a filter for monitoring and intercepting SMTP connections
between a remote host and a qmail server.

When a connection is established from a spam source
(as determined by the active filters), spamdyke will reject the email
qmail never sees it.

Beyond filtering, spamdyke offers a number of other features:
• spamdyke supports SMTP AUTH and will even provide SMTP AUTH to an unpatched
qmail server.

• spamdyke supports TLS and will even provide TLS to an unpatched qmail server.

• spamdyke provides much better, much more complete logging than qmail,
using syslogd.

• spamdyke can log all SMTP traffic to aid troubleshooting.

So folks, this might worth to try

Restart apache, and Voila ! phpmyadmin works again !
