i am interested in antispam application which is compatible with cPanel /WHM. we are using spamassistance but not happy with results - any inputs from experience guys - who can recommend couple of commercial / non commercial options
Check out http://www.configserver.com -- they have a MailScanner installer for cPanel. If you're unfamiliar with MailScanner, I'd recommend having the ConfigServer staff install it for you. We've used it on several servers with very good results when properly configured.
Located in Atlanta, GA and Los Angeles, CA
Dedicated Servers, KVM, Xen & OpenVZ VPS, Co-location, R1Soft Data Backup, Shared & Reseller Hosting
I cannot recommend configserver, well...they have good support, but the solution is not good enough.
You should expect load increase a lot (because of mailscanner and some other itens on config).
We start to have a lot of problems with our customers with emails beeing lost, problems with aliases on cpanel, emails from -> to the same server sometimes are tagged like SPAM or disappears, their default config deletes mail queue of users that get mailbox full.
You probably will need to fix a lot of things, my impression is that their solution is designed for EXPERIENCED users, not usual commercial/personal customers as we get everyday on hosting business.
