Thunderbird: форум сообщества

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.

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...

Some mail in my spam folder is marked with the red flame spam icon, and some isn't. It's all spam -- that part is okay. Thunderbird has sorted everything correctly. But why wouldn't everything in the spam folder be marked as spam?

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.

Folder one: Spam .... this is the new one, automatically installed through a thunderbird program . Mails by filter marked as spam now get sent to THIS Folder. ____________________________________________________________________________________ Folder two: Spam .... this was up to now the correct existing one. ('Spam gemeldet' means: Spam mails sent to the government anti-spam authority.) So: this folder nr. 2 should be eliminated, as the folder nr. 1 seams to be the normal working one.

Thank you very much for your help! Peter

Since yesterday (27 Apr 2026) any and all mail that comes into Thunderbird gets marked as SPAM. I searched online and found people saying that I could reset the junk training filter, so I did this, but incoming mail was still marked as spam. The next suggestion was to delete the training.dat file. Did that, restarted Thunderbird and incoming messages are still marked as spam. The last suggestion was to turn off adaptive junk mail controls. Didn't want to do that because I assumed that it would let spam through. Nope. Turned it off, restarted Thunderbird and two emails from my work came in and got flagged.

I'm running version 140.10.0esr (64-bit) on Windows 11. I am using IMAP to connect to the mail server but it's not running any spam detection software (like Spamassassin). I know this because it's my server and even if it was, no updates have been preformed since the first of this month and this just started happening yesterday. Combine this with the bug that Thunderbird notifies me of incoming mail, even if it's spam (didn't post about this because there are plenty going back a couple of years), is starting to make me look for an alternative.

Hi Team, I right click on a message header and select "mark as spam" which then deletes it but it will let another message from the same place in at a later date, is there a way to have the messages I mark as spam go straight to the spam folder?

Thanks, regards Steve

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!

Please inform me how I can mark senders in Thunderbird as not spam or is there a list of secure senders so their mails will not go to spam folder?

I want to create a filter to match any of the 20 addresses on my list. Rather than manually repeating the 'add rule' 19 times, I hoped to import all 20 at once.

Creating a filter with 'to' and putting a comma separated list there doesn't seem to work; the addresses won't be matched. I can't find a config file to manually edit in my profile directory for filters, or an extension to create this filter.

My end-goal is to add this 'blacklist' of my old e-mail addresses that have been leaked to a spam filter. These messages already end up in my spam folder by a rule at my provider, but I want to mark them as spam too, so I can sort through the spam folder more easily to find false positives.

Thanks in advance!

Feature Request: When a user reports spam to an official agency (e.g., report@phishing.gov.uk), Thunderbird should automatically detect the endpoint using pattern matching and prompt the user to forward the message as an attachment (.eml format) rather than inline, preventing the loss of critical routing headers like DKIM, SPF, and Received: chains necessary for cyber investigators. This logic could either intercept a manual forward with a prompt asking to attach the original source data, or as an alternative, it could be integrated directly into Thunderbird’s existing "Spam / Junk" button to automatically package and auto-route the pristine email source data to the designated agency upon click.

I have been using Thunderbird for a very long time. Today is the first time I have seen this happen.

In the column on my left side that has my account and folders for those accounts it is showing 5 in my junk account. But in the preview window to the right of that column there is nothing showing as far as any entries as junk mail. It is completely blank. What do I need to do to clear this 5 from the left column Junk folder??

I have tried resetting the machine and that did not work. I even went into the webmail site for my email provider and there is no junk email showing there at all so as far as my email provider goes, it looks like everything is working there.

For the past 2 days, either my inbox is empty on startup, or if I see my messages, they disappear completely once I open any folder. Also, I have over 2400 messages in Trash, and can't empty the folder. No settings or connections were changed. What gives?
