I installed CleanMail, but I still receive spam mails. What am I doing wrong?
After installing and configuring CleanMail, you also need to change your mail account settings, as described here. Also, CleanMail will only tag spam mails, and not delete them. To get rid of spam mails, you have to set up a filtering rule in your mail client to remove all mails tagged “SPAM” from your incoming folder.
