The spam filter software of cpanel has one problem: Sometimes it marks wanted mail from friends or partners as spam. This makes this mail unreadable but much more important is, that I cannot use the discard function for marked mails.
The new spam folder is no help, because I have to check the mail there too and it makes no difference where I have to do this.
I would like to suppose to insert a white list function into cpanel. Each mailadress I put into that list should be not become checked by the spam software.
I think it would be quite effective to use a white list together with the discard function.
