Unfortunately, after entering the correct email and password, I get a message that "Cannot log in to the server. Probably the username, password or configuration is incorrectly set". I have no knowledge of how to do this. Perhaps the problem lies with the wp.pl mail provider. Please help me so that I can use your product. </blockquote> The settings for wp.pl accounts are here: https://pomoc.wp.pl/jak-skonfigurowac-program-pocztowy Note that if you have two-step verification on the account, use an app password in TB instead of the account password. Instructions are indicated in the above link.
