Secure my mail servers and harden the OS of my VPS

Ukončen

Popis

Hi,

I've been having trouble with people sending spam through my smtp server. I took some steps to stop it and I believe I succeeded but my legitimate mail volume seems to be down. I need somebody who knows how to secure CentOS, running apache2, cpanel, iptables, exim, whm etc... I have registered with a white list service so I will need to have that implemented as well.
