Please only view if you have experience in WHM and ASSP Spam Filtering.
We host over 100 domains and email is extremely important. We are on a VPS Server.
ASSP is used for spam filtering
ConfigServer Security & Firewall - csf [url removed, login to view]
CENTOS 6.5 x86_64 virtuozzo – web - VPS
Issues that are reported -
1 - Some locations can not connect to the server for mail - When i have disabled the firewall or added them to the exception list they are able to get in, this concerns me. It is not just email that people can not get, it is to the websites also.
2 - Email is being stripped to text format from html. (On some domains) (SPAM FILTER??)
3 - Emails are not able to be sent or the sent gets a message "to try again later" ((((Might be a port issue?))))
4 - System Check and Update
5 - Any recommendations to be made
