Hi everyone A few days ago, my emails would not send. I recently updated to Version 115.3.3. Mac OSX 10.13.6 On sending emails I get the following ERROR MESSAGE Login to server mail.XXXXXXXXX.co.uk with username [email protected] failed. Emails are still received, so I am logged into account. On re-entering password a few times, I then get following ERROR MESSAGE Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mail.lockboxstorage.co.uk timed out. Try again. I have checked Server & Outgoing settings and all are well. Server Settings Server Name: mail.XXXXXXXXX.co.uk Port: 993 Username [email protected] Connection Security: SSL/TLS Authentic Method: Normal Password Outgoing Settings Description: Not Specified Server Name: mail.XXXXXXXXX.co.uk Port: 465 Username [email protected] Connection Security: SSL/TLS Authentic Method: Normal Password Have deleted account from TB Have deleted stored passwords from TB Re-added email account - Account reloads and new emails are received Have changed '''security.tls.version.min''' via Cofig-Editor to 1 - emails still not sending Any other suggestions? Is it something to do with folder locations, cache, profile? None of these have been changed since TB was working with perfectly?
