by checking in site's log :

POST /comment.php?type=trackback&entry_id=20
HTTP/1.0 200 87 - TrackBack/1.02

Linux 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 :-)

Debian Linux "Client does not support authentication protocol requested by server;
consider upgrading MySQL client"

Arrrgh !

Quick look at phpmyfaq gimme the solutions, tho'...

My mysql server's version is 5.0.18-Debian_8, My PHP version was 4, and I use Apache2,
they said the mysql lib of php4 is too old for the server.
so I upgrade php , its mysql lib, and php5 module for apache2 :
apt-get install php5 php5-mysql libapache2-mod-php5

Restart apache, and Voila ! phpmyadmin works again ! :-)
