I can turn the SpamDetector on using the email settings spamdetector radio button, but when I click the "Save" settings button, I get an error message that says the settings were unable to be saved and the detector gets switched off. Being overrun with Spam and tired of manually chasing spammers. Would be nice to be able to block subdomain IPs, but I think the filter ignores partial IPs. Any ideas? Doesn't matter what computer or browser is used. Results always the same.
