Does anyone know a tool that allows to assign an email address or subject heading to a specified folder with just one click? The method of spam filters to discriminate emails by means of a keyword is not sufficiently reliable (important emails can easily be deleted as spam). The only save method is to assign individual email addresses or subject lines to a specified folders. For this task, the filter tool of Thunderbird is too compicated. It requires several steps (1. click on email address of email; 2. select filter in drop down menu; 3. select folder (several clicks); 4. click on return; 5. click on o.k.; 6. click on "Execute now"). Helpful would be a tool that allows to generate one (or several) button(s) that complements the buttons "Answer", "Delete", "Junk" in the frame that shows a newly received email. The buttons that are generated could be "Assign emails with this email address to filter A" (in brief: "Filter A, email address") and "Assign subject heading to filter A" (in brief: "Filter A, subject"). Those buttons would allow to easily build up a precise filter for spam that filters only emails from specific senders or with specific subject lines. Does such a tool exist? If not, could the programmers of Thunderbird provide this? Thanks in advance. Samuel
