Intermittent failure to send emails on Thunderbird
For a few weeks I have had a new problem on my new Windows 11 Lenovo laptop, and also on my wife's older Dell laptop. We have been using Thunderbird for years without major problems. I loaded the latest version of Thunderbird on my new laptop and it seemed to work ok at first. Now I have a problem with intermittent failure to send normal emails on Thunderbird. My wife has noticed the same problem on her laptop Windows 11. I asked iPrimus support (who are supposed to support Hotkey) but they say it is not their problem but Thunderbird's. We RECEIVE emails ok, and sometimes pressing SEND will work immediately, sometimes on the second press, and sometimes not at all. This generates a message "-- Unable to authenticate Outgoing Server (SMTP), smtp.hotkey.net.au -- Check password and verify authentification method in Account settings/Outgoing server SMTP" We both use Trend virus protection.
Account name: mail.hotkey.net.au Outgoing Server: smtp.hotkey.net.au Server Settings: Server name pop.hotkey.net.au

What is your anti-virus software?
Trend Micro Maximum Security, updated regularly.
Try to start Windows 10 in safe mode with networking enabled.
Does the problem go away?
Windows safe mode disables anti-virus software. This is a troubleshooting step, not a solution.
I tried that and also exiting Trend but neither helped. Eventually I rummaged around in Account Settings, and found that Account Name and Outgoing Server settings did not match the previous computer's. I changed them to "mail.hotkey.net.au" and "hotkey-smtp.hotkey.net.au" and so far it's all working smoothly. Fingers crossed! Thanks.
