How to select/filter an incoming email of a designated email address to go to a sub-folder in the In-box?
(1) Many emails of the same email address were received in the In-box; (2) For better management and control of these email, I wish to select all of them and file them in a sub-folder under the In-box; (3) Further receipt of email of this address will also go to the same sub-folder automatically; (4) I wish to know how this setup can be made in my Thunderbird account.
