Antispam toolbar not working in Thunderbird
I've installed the trial version of Internet Security 2017 in order to test it out before buying. However, it seems that the anti spam functionality isn't working properly. It seems that the spam is correctly detected and tagged, but it's still delivered into my mailbox.
The antispam toolbar in thunderbird appears to be active (I can click all the buttons), but doesn't seem to be working properly. Clicking the 'Is spam' or 'Isn't spam' buttons doesn't do anything.
Any idea on how to fix this?
