Sending of the message failed after Ubuntu upgrade

I've had Thunderbird running for a few years now without any issue. Last week I upgraded from Ubuntu 22.04 to 24.04 and ever since that I've been having problems on Thunderbird sending email.

I can receive mails fine but if I try to send emails from any account I get "Sending of the message failed"

I've for 2 Outlook.com accounts and one gmail.com account and all give issues.

GMail I'm using: smtp.gmail.com Port 465 SSL/TLS OAuth2

Outlook: smtp-mail.outlook.com Port: 587 StartTLS Auth: Normal Password.

These settings have worked fine before the upgrade so think there is something broken my TB.

Same problem - I don't think it's the outbound settings as all 3 accounts have stopped working.

I think it's something to do with when upgrading to Ubuntu 24.04 TB was moved from a .deb package to snap.

Anyone have any idea how to solve this?

SNAP packages are sandboxed.

My guess as I have not used Linux in any way for years is that there is some SNAP permission you need to set to allow your snapped version access outside the sandbox.

This might offer some clues https://snapcraft.io/docs/interfaces
