HELLO: My ISP provider is Comcast and I can eMail from their eMail system - do not like it. I always use TBird eMail. Recently got hacked and the Turds bulk mailed the whole list. Now my TBird App is giving me this error code as shown below. The system settings have not changed that I know of. Just my Password has changed and that works because I can access the eMail. I just cannot send anything out. I would be grateful for any suggestions as to how to fix this problem. Thanks!!!!
