Hello guys I have.

One of my clients has a major problem with the whitelist on cpanel
The whitelist seemed to stop working after placing about 360 e-mails in it. It just stopped working one day and we noticed that by cutting the e-mails into half everything is working just fine right now. So clearly the whitelist from spamassasin is limited.
SO I guess my question is if anyone has any solutions.

Whether it is fixing this program, or switching to another one.

If the only solution is replacing program, which program should I get, and I do I install it into cpanel.

Thank you for your help
