Thunderbird very very slow. Caused by the anti-spam part of Bitdefender
Downloading emails works quickly as normal but reading opening or looking at emails (even ones downloaded weeks ago) is suddenly very slow. There is a pause before anything can be viewed even with a preview screen open.
Version is 128.7 0esr I use bitdefender - but that has never been a problem before Any ideas?

Hi there Thank you for your suggestions. I have worked out what is causing the slowdown and how to stop the problem though it's not ideal. Bitdefender has an anti-spam filter, which is very useful, once you tell it that an item is spam, it will block all new messages from that address and look for similar messages... However, it doing so, it slows the email system down a lot... So the solution is to turn of the anti-spam part of bitdefender.

Start Thunderbird in Troubleshoot Mode. The following article explains how to do that and why it can be useful to help identify the cause of a problem:

Start Windows in Safe Mode with Networking mode. You may have to connect your computer to the router with an Ethernet cable, WiFi is disabled in Safe Mode:

Does any of that make the problem go away? This is how you may know whether the antivirus could be the cause…

Unfortunately you (and I) may not have seen prior posts/responses in the past few weeks because the notification system was broken.
