Since I was upgraded to Thurnderbired 91.4.1. I have been unable to send emails to gmail addresses. My emails are bounced back by gmail with this message.

This may not be anything to do with the Thunderbird upgrade - I know of other systems not using Thunderbird that have started getting similar bounce backs recently. Just to prove that, try sending from your webmail to a gmail address and see if the message fails. Gmail has probably tightened up their requirements. Your email provider needs to ensure that all the authentication requirements for their outgoing email are in place. See https://support.google.com/mail/answer/81126#authentication
