Mozilla suggests using these methods if you are unable to send messages.
You can check them on support.mozilla.org on the email settings article for the particular email service provider like Gmail, Hotmail, Yahoo, etc. In case no such article is available, check the website of email client for Mail SMTP Settings.
In most cases, you cannot send messages using Thunderbird when you try to send emails from one account using the service of another account provider, like you cannot send email from firstname.lastname@example.org using the SMTP server of Gmail.
Users also need to verify whether the Windows firewall, anti-virus program or ISP is responsible for this problem.
Note: Anti-virus program or firewall often blocks Thunderbird outgoing email after a Thunderbird update as they do not recognize the updated version. To resolve this, remove Thunderbird from the list of trusted applications and add it again manually when prompted.
Users can also try deleting their password for SMTP. But keep this method for the last. If Thunderbird is not sending messages after an update, do not perform this step as there might be no problem with the SMTP password.
As the last resort, you can also try changing the SMTP password. For that, visit the support password of ISP and fill the ‘reset email password’ form. Go for this solution to fix Thunderbird SMTP error only if nothing else works.
