We have not been blacklisted at Spamhaus.com. Yet, Thunderbird ONLY is blocking of email sent via its SMTP. IP being blocked according to Spamhaus is 162.xxx.xxx.xxx But Spamhaus shows that neither this IP nor my email, [edited] @wrigleyranch.com is being blocked or blacklisted. We are able to send email thru our email client at BlueHost. So, it is definite that we are NOT BLACKLISTED. The last update (automatic) by Thunderbird was January 14, 2026. I'm am suspecting that this update has caused this error. That's why I'm writing you. Can I revert to the prior Thunderbird update to test this theory? I cannot see how to do that. I need help!!! Receiving email is unaffected by this malfunction.

While reorganizing and renaming a local mail folder it has become inaccessible from Thunderbird. All the other folders are fine.

The folder name is BSW and the BSW file is present, so are the .msf and the .sbd. 1. I tried repairing the folder, no difference. 2. I've tried shutting down Thunderbird, deleting the .msf and restarting. No change in behavior but the .msf file is recreated. 3. I tried shutting down Thunderbird and renaming the files. No change.

Name Thunderbird Version 140.7.0esr Build ID 20260109054016

Is there another way to get Thunderbird to access the folder?

Sorry - I feel as though I'm monopolising this forum at the moment!

In my Menu bar, I have Delete, but, using this, I can only delete emails from the Unified list, not individual accounts. I CAN delete from individual accounts if I select the email, right click and select delete. Seems odd

Sehr geehrte Damen und Herren, plötzlich sind von allen Konten die Unterordner mit allen Mails verschwunden. ES gibt auch kein Junk Ordner mehr. Wie kann ich es wieder herstellen? Mit freundlichen Grüßen, Matthias Brockmann
