Despite my marking messages several times as NOT spam, Thunderbird keeps on and on RE-marking them as spam. And the mails are coming from one of my own addresses, and they ARE in my address book!!!!!

There seems no way that I can stop the beast from misbehaving.

A substantial portion of email spam that I receive has a couple of characteristics: - the subject line includes "Sonic", and - the sender is plainly not Sonic.

For example:

Return-Path: <live1@tomokawasaki.or.jp> Received: from tomokawasaki.or.jp (tomokawasaki.or.jp [122.1.223.161]) by mwb-sdgw-mts-005c1.ocn.ad.jp (Postfix) with ESMTP id 063B61400008F for <ronks@sonic.net>; Sun, 19 Jul 2026 07:07:06 +0900 (JST) From: =?UTF-8?B?U29uaWMg0JLRlmxs0ZbQv2c=?= <live1@tomokawasaki.or.jp> (From translates to "Sonic Billing" here; in other spam it is cleartext) Subject: Automatic Payment Unsuccessful To: <ronks@sonic.net>

I am wondering if it is possible to construct a filter that says basically: If Subject includes Sonic AND From does not include Sonic Then Send to Trash (or mark as spam or whatever)

Can this be done?

The sent message is deleted but I get Filter action Failed.

I have 6 email accounts linked to Thunderbird. I noticed today on one of the accounts, along with inbox, drafts, sent, etc., there is now a spam icon. I didn't change any settings or even look at that email account today. This is the only account with that icon and it won't allow me to delete it. All settings between all accounts are the same, just this dang spam fire icon that I can't delete

J'ai 4 boites de messagerie Orange (France) : Boite 1 envoie un message qui va "anormalement" en "Indésirable" dans la boite 2, au lieu d'aller en Courrier entrant dans la boite 2. Comme si la boite 1 n'avait pas le droit d'envoyer un message vers la boite 2, 3 ou 4...

When I get spam email in my inbox, I mark it as SPAM. It will arrive again in a couple of days. Why does it come into my in-box still? Its marked as SPAM in my In-BOX!

I don't want to keep touching junk email!!! its a huge waste of time. I cannot find the settings on how to make that action happen.

Please advise. If this isnt possible I will unfortunately be leaving your platform after decades of use. Yes I have donated several times over the years. Not get rich money, but it all helps.

When I receive a junk email, it spends a brief time in my inbox before being moved to the spam folder by the automatic classifier of Thunderbird. In that brief window, the notification system already displays the notification. I found no way of changing that behavior. Is this normal behavior? How to change it?

I am new to Thunderbird, and attempting to use it as my email client. So far I have imported my main Gmail account, a second Gmail account, as well as three different Microsoft accounts. There is a duplicate Spam folder on one of the Exchange accounts, which I assume came with the import. There is, however, no way to delete the Spam folder from the original MS account. None of the other accounts has this issue, although when I had duplicate Trash folders on Gmail accounts earlier, I was able to delete them from the original account, which allowed them to disappear from TB. The Spam messages in TB actually only populate into one of the Spam folders. Any ideas what else I can do to get rid of this superfluous Spam folder, please? Many thx for any help!
