Mailserver Security (WHM/cPanel)

The site needs to update its RBL checklist...two of its RBL checks will always return a positive:

My site got a 92% score, which is fine with me. It knocked off 8 points for having an open port 110...even though port 110 only accepts secure authentication.

Most attacks on my site originally came through port 21 (FTP). I changed FTP access to port 2100 and closed port 21, and the difference was very noticeable.
Yeah, I noticed they had RBL in there. I went ahead and closed port 110 since secure pop connection should be coming to 995 anyway.
Looks great RMedure! If you could post it in the cPanel how to forum that would be great as I am sure that others would find it to be of great help! :D
