Marking junk e-mail with "J" doesn't work.

Marking junk e-mail with "J" doesn't work.

Could you please clarifying what you mean?

Are you talking about pressing the letter "J" on a touchscreen or physically keyboard? Is the question in relation to Thunderbird for Android (this forum) or the desktop version?

Emails marked as spam in the mobile app are simply moved to the spam/junk folder. The app does offer any spam filtering. Email providers normally filter spam and allow users to create server side filtering rules.

I mean when I press J on the computer keyboard I used to be able to automatically get rid of spam e-mails but now it doesn't work on Thunderbird. Thanks.
