Yesterday I upgraded TB to v91.1.1 and since the upgrade I have been unable to send HMTL formatted emails via Thunderbird (can still send plain text). The diagnostic code from the sending server is:

Diagnostic-Code: smtp; 550 Maximum line length exceeded (see RFC 5322 2.1.1).

I haven't had any issues with TB previous versions (have been using TB for about 30 years) and it is the first time I have struck the error after an update to TB.

I have uninstalled TB and reinstalled the latest version - this made no difference.

Does anyone know if this is a bug with the current version where it is creating extra long line lengths in the send code?

The patch for bug 1729437 will hopefully appear in 91.1.2 next week.

Cheers, I thought I was going a bit mad. I even tried resending HTML emails to myself that I had sent before the upgrade to TB 91.1.1 and they had the same notifications of failure to send.

Hopefully the bug is fixed promptly as I like some of the new features in 91.1.1...and don't particularly want to have to take the time to rollback to a previous version.

Have tried the fix outlined above, but still having the same issues.
