I never had any problem with the older version of Thunderbird, Mailwasher Pro was able to send the mail I was keeping, right into Thunderbird, and ONLY then did it come into Thunderbird. With the new Thunderbird downloaded version, 144.0.1, If Mailwasher is not already open to receive any email from Comcast, It goes right into Thunderbird before I open Mailwasher Pro and choose the emails to keep, mark as spam, or blacklist. It has become a real problem, but I can find no way in the settings to set it as receiving the email 2nd, after Mailwasher "washes" the mail to it. Why did it always work correctly from the beginning, but not now?
