Thunderbird Community Forum

Starting today (September 3), ALL of my received emails are being put into the Spam folder instead of the Inbox.

FYI, I have been running Thunderbird (TB) for years and have not recently set up any new filters.

I'm currently running Thunderbird 64-bit version 155.0 under Windows 11 Home version 25H2. I am also running Bitdefender Total Security, but I have turned off its Antispam function, both under my usual Standard User account and the Admin account.

I have tried:

1. Going into TB Settings|Privacy & Security|Spam and clicking on "Reset Training Data." 2. After closing TB, I deleted the training.dat file in my TB profile folder and restarted TB. 3. Right-clicked on my Inbox and Spam folders and clicked on "Repair Folder." 4. Exited TB, copied my profile folder to an external HD, uninstalled TB and reinstalled TB after downloading from the official download site. 5. Rebooted my PC.

None of these approaches has worked to solve my problem.

Thanks for any help you can give.

Hello: I send out newsletters to about 100 senior men golfers. I've been struggling with my messages going to spam or junk folders. My messages don't contain spam, but some mail servers are rejecting them. I've been working the problem (proper server authentication, DMARC, SPF, DKIM, etc.) but one of the suggestions I've read is to make sure there's an "list-unsubscribe" link in the email header. I've placed one in the body of the email at the bottom of the page (still fails), but how do I make a header in Thunderbird in which to place a link? Thanks for any help.

Ich erhalte täglich mehr als 100 Emails mit Werbung. Was muss ich tun damit die Werbung gesperrt werden. Der Filter bei Thunderbird separiert die Mails zeigt sie aber an.

I upgraded Thunderbird a few days ago to 141.0 (64 bit). Today, I note the spam folders in both of my email accounts are missing. So where is spam email going? Is the software automatically routing it into the JUNK folder? If not, how do I resurrect my spam folders?

I have recently started using Thunderbird as my email account. I have two email accounts and the first account has a Spam Folder but the second account doesn't. I tried adding a Spam Folder but it will not allow me to do so. Would like to understand why that is.

I set up a message filter to send junk emails to a 'junk' folder, but then the junk folder just shows new email. Is there a way to make the filter mark the messages as read?

A couple of suggestions.

1) After opening an email marked as spam (by Thunderbird's spam filter), there is no option to confirm that this is, indeed spam. The email can be marked as "Not spam," but not confirmed to be spam. Unless I'm missing something, I have to go back to the inbox, mark it as spam manually, and then it is automatically sent to the spam box.

2) Assuming I understand the spam filtering correctly, once Thunderbird marks emails as spam, they remain in the inbox for at least 1 day (or longer if desired). I would like to have those emails sent IMMEDIATELY to the spam box, where I can still examine them to make sure they're spam before deleting them.

That way, the inbox will have only emails that either are not spam at all and those that haven't been marked as such.

As the system now works -- unless I'm misusing it somehow -- once the filter marks emails as spam, I still have to wade through them to sort out the good ones. In my view, that pretty much defeats the purpose of having the filter in the first place. I still have to "mark" them as spam again to get them sent to the spam box.

Perhaps I should note that this inbox gets dozens of spam emails every day and that I check it multiple times per day.

Hi, Since yesterday, the messages I receive are in code. My provider is Orange (France). Of course, the messages are not coded in my Orange mailbox. The protocol I use is pop. It looks like all messages are considered as spam. I switched off Bitdefender without solving the problem. Messages start like shown below. Thank you for your help. Alexis

My Trash Folder has disappered, no longer appearing under my email account. I can access only: Inbox, Drafts, Sent, Archives, and Junk. When I try to create a Trash Folder under my email account I receive a message that I already have that folder. I uninstalled, then reinstalled, Thunderbird on the possibility that the program was somehow corrupted, but I still cannot see, nor access, a Trash Folder.

If marking messages as Junk help train TB, does deleting ALL messages in the Junk folder also undo that training, by getting rid of junk mail "models" TB uses for evaluating incoming new messages?

I'm new to Thunderbird and it works great. One question though, why doesn't the junk mail folder auto update with unread emails like my other folders? It seems I have to manually refresh to update only the junk mail folder.

While looking for another setting, I noticed that a setting about how T-Bird handles spam mail. I have it checked. Today, I received a DOOZY of a spam mail, but Thunderbird didn't flag it. It was so obvious spam, as it asked for credit card, banking, automobile license! Also, the Subject asked to update payment info, but the From field wasn't that company.

I have 4 email account. One account will not allow me to delete or send to junk box. When I press delete nothing happens. The emails (at least 30) that came in are marked junk too. The other 3 account work fine. I have had these 4 account for years and never had a problem. I have done a complete scan with Norton and nothing came up. Thank You in advance

I tried unticking enable and it did NOT work. Help! I want the stupid filter gone. I have struggled for two years with the junk filter which does not work right. I have done shift J. The filter does NOT learn. A week aog, I saw that I could uncheck enable and that was supposed to stop the filter. That also did NOT work.

Today, an email I forwarded to myself from another platform went in junk. I never wanted any junk filter. It has been nothing but trouble and now I can't even disable it.

Bonjour,

depuis cette après midi et alors que tout marchait bien ce matin tous mes mails entrant sont systématiquement classés en spam et illisibles. Le nom de l'expéditeur et le sujet du mail ne sont plus lisibles non plus et sont tronqués.

J'ai essayé de m'envoyer des mails de test et je reçois un mail tronqué illisible. en image je vous envoie le mail envoyé et ce que je reçois. Tous les mails entrant quel que soit l'expéditeur sont traités comme ça.

Merci pour votre aide car je ne peux plus rien faire et j'ai vraiment besoin de mon mail en ce moment.

Am I doing something wrong?

I have one account in Thunderbird that pop's emails from a Yahoo account. If I delete a message in Thunderbird it goes to a local trash bin and on default stays there forever.

I want the emails to be deleted after 40 days in the trash bin. See picture. But it looks like it works exactly like it's described.

Messages are deleted from the trash when it's 40 days after they were originally send. If I delete a message in the inbox older than 40 days it goes to the trash and is immediately deleted from it.

I tried deleting several messages older than 40 days.

The counter of the trash increases for a split second with 1. If I look in the trash the deleted message is not there.

In my trash there are only messages "younger" than 40 days. At this moment the oldest is from December, 14 2025

Yes it works like the retention policy tells it should work. But this different from what I expect from trash folders
