Thunderbird quit working on my Windows 10 laptop today, it doesn't send or receive emails.
Thunderbird was working fine until this morning on my Windows 10 laptop.
Now when I try to download email the circle spins, the green bar moves across, but no email downloads.
When I try to send an email I get the following error message:
An error occurred while sending mail. The mail server sent an incorrect greeting: Cannot connect to SMTP server 2603:1036:302:4080::2 (2603:1036:302:4080::2:58
