Hello Mustafa,
Sad to know what happened with the forum and crash...
I found that following would be so fantastic to have it integrated in Kloxo-MR as a builtin package:
http://configserver.com/cp/csf.htmlIn particular, I found the "
Port Flood Protection" as one of the MOST IMPORTANT TOOL to block connections EVEN BEFORE THE SPAMDYKE plays its role.
I have configured as follows:
PORTFLOOD = 22;tcp;1;60,25;tcp;3;60,80;tcp;10;60
---> 25;tcp;3;60
which means that the csf (firewall) shall allow within 60 sec. ONLY THREE CONNECTIONS from a particular IP on Port 25.
Spamdyke will not even be activated for processing as csf blocks the connection activity so beautifully.
Since many days, I see port flooding on 25 port. Hence, this solution is a must.
Kloxo-MR comes must later. In the sequence, CSF ---> spamdyke ---> Qmail/Kloxo-MR.
