Thunderbird - Email Hangs on Sending - SSL Settings



Upon initial setup of inputting your email address and password, Thunderbird grabs the server settings for incoming and outgoing mail.

Everything looked right at first and emails starting rolling in. However outbound emails just hang. Upon closer inspection the outbound port is correct however the "Connection Security" states "SSL/TLS" and not "STARTTLS" as my mail server requires.

So I'm not sure if it's pulling "SSL/TLS" from my mail server or it's the way Thunderbird is interpreting it.

Note: These settings are for my mail server, yours may be different. Check with your provider.

Thunderbird version is v102.2.0 (64 bit).

  • Verify port is 587.
  • Change "Connection Security" from "SSL/TLS" to "STARTTLS".
Test email sending again.
