My junk email has increased dramatically lately. I'm sure it's just life on the internet but I'm trying to figure out if clicking "unsubscribe" actually does anything. I've been putting all the emails that I click "unsubscribe" into a separate folder. I'd like to sort the folder by the email address of the sender. However, when you click on the "from" selection in the message window it gives you the entire entry that the sender put in the send section. In other words I see "The Scary Law, Thomas T. from NFE <daily@today.newfinanceera.com>". Is there a way to get a column that just shows the "<daily@today.newfinanceera.com>" so I can sort on that item?

I want to change the folder to which I currently send my spam filters on my Mac. I understand how I can edit them individually and handle new filters, however I have several hundred accumulated filters created over the years and doing so individually will be very time consuming. Is there a method I can use to change all existing spam filter's destination folder in a single step. I know a bit about using Config Editor, Chrome css, probably just enough to get my self in trouble. I see several spam filter files within the Thunderbird folder, but not sure if they are germane.

Any help will be greatly appreciated.

I have noticed the number of messages in my spam folder growing. When I check what's there I find that many are not spam and they haven't ever appeared in my inbox. Sure, I can drag them back over but that's not ideal.

How can I control what goes into my spam folder?

Brand new imported domain email account. I accidentally clicked on "Run Spam Controls on Folder" for the inbox for this account, and it marked over 4,000 emails as spam! How do I undo this? Delete the account and re-import it? I didn't set up any filters; I just set up a few tags, marked about 30 emails as spam, and deleted them. That's it.

My name is Yoshinobu OKUMOTO. I live in Nara prefecture in Japan. I use Thunderbird as my e-mail software. My e-mail address is "<edited>@asahi.email.ne.jp". I have received a mail at January 29 18:35, 2026 . In the space for name of a sender of the mail, "<edited>@asahi.email.ne.jp" is written. This is my e-mail address in Thunderbird. I did not sent a mail at January 29 18:35, 2026 . I wonder who sent this mail to me.

When this mail was sent to me, a red spam mail mark was attached to this mail. Usually, when I received a spam mail, I transfer the spam mail to a spam mail folder. But in this case, if I transfer this mail to a spam mail folder, I worries that transformation might transfer a mail from my acquaintance to the spam mail folder from that time on.

In the main body of the mail which I received at January 29 18:35, 2026, it was written as follows.

" Account is invalid.

When this page is displayed, the total of the account "asahi.email.ne.jp" is invalid.

The procedure to confirm the reason 1. Log-in with a browser, for example Chrome, to the account "asahi.email.ne.jp." 2.If the account is invalid, the explanation is displayed."

In the sentences mentioned above, " Account is invalid. When this page is displayed, the total of the account "asahi.email.ne.jp" is invalid." But I can use my Thunderbird as usual except this mail.

Next, I tried to log-in to the account "asahi.email.ne.jp" with a browser Chrome, I could not log-in.

I already received this mail which have the same text three times until now, 1/20 19:17, 1/21 17:21, 1/24 21:04.

If it is necessary for me to forward to you the mail which I received at January 29 18:35, 2026, I send the mail if you inform me of your mail address.

I will be thankful, if you give me some advices in this case.

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.

Is there a way to have TB auto delete Trash msgs older than a specified number of days. I don't want to just empty all the Trash folder, but I would like to be able to tell it to empty all messages over 30 days, or 42 days or whatever. Suzanne

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

I have an email filter set for a domain that has been sending many spam messages. It was working but now they have started to use my name portion of my email address in their email address. For example, if my email address starts with bobp@ then the email address at the top of the email is bobp@ncqkl.com. The domain is real.

The only option for the first column of the filter I am aware of that can be used is "From", "Contains" and "Email Address". I don't believe Thunderbird allows domains. I have tried ncqkl.com to no avail. Somehow they are getting around filters by using your email name portion. They were also using multiple different addresses all with the ncqkl.com domain.

Is my best bet to use the adaptive spam system? I haven't really used it in the past as I haven't needed to. I don't get much spam usually as I don't have much of a presence on the net. Just lately the amount of spam has increased considerably.

Thunderbird sends me spam reports, but I cannot open the mails considered to be spam, nor do I habe a spam file. I only have a junk file, but this does not contain the mails considered to be spam in the spam reports I get. Recently I received several mails I could not open because they ended up as spam. Why do I have a junk file, but not a spam file where I can decide if the mails are spam or not?

TB 140.7.0 32bit, Windows10 64bit

My email provider implements black-box spam processing, with deemed spam redirected into a "Spam" folder at the server end which by default is flushed every 60 days.

To view all the incoming mail, I now not only need to view the account Inbox as TB presents it, I also need to log in to the provider's Web interface to inspect the account's Spam folder. I'd rather view this Spam folder through the TB interface to avoid extra logins.

So I

(1) Created a Spam subfolder under Local Folders using the TB interface. The Properties function reports its path as mailbox://nobody@Local Folders/Spam (the Inbox path is reported as mailbox://nobody@Local Folders/Inbox). These paths are read-only as presented by the Properties function.

(2) Used the Config Editor to set mail.server.default.check_all_folders_for_new to TRUE.

(3) Restarted TB, verified that check_all_folders_for_new was indeed TRUE.

However, while the account's Spam folder was known to contain 2 entries at the server side, the end-user Spam folder was not populated, whether by way of TB restart or manual invocation of the Get All New Messages function.

Any ideas ?

Thanks.

When I Try to send a message via my Internet provider, SFR, I receive the windows :

L’envoi du message a échoué. Une erreur est survenue lors de l’envoi de l’e-mail. Le serveur de courrier a répondu : Client host rejected by spamhaus for spamming issues; please refer to Listed by XBL, see https://check.spamhaus.org/query/ip/xx.xxx.xxx.xxx for further information. Veuillez vérifier l’adresse du destinataire xxxx

SFR, don't give aid for this problem, and ask to address to Thunderbird.

How does one take away many entries in Trash with one sweep instead of one by one? I was able to do this before my marking all of the items and then clicking CTRL and X, but that no longer works.

I am running Thunderbird 140.6.0esr on a Windows 10 desktop PC. Yesterday I was accessing my inbox and had a problem. I marked a message as Junk in the message bar. My virus software, TotalAV, flashed up a Red message box say HTML issue - Junk. Following that Thunderbird gave a message saying Junk folder full and greyed out the button on the Message bar. Then the Junk folder disappeared from my folder list and now pressing Junk for a message causes no action. Before the Junk folder disappeared it had 2 unread messages.

My Junk settings say "Junk" folder on: my account name.

I do not know how to proceed. Please help.

Some time ago I found a way to make Thunderbird mark Junk emails as [SPAM] but still to deliver them to my Inbox rather than to the SPAM folder. I need to do this on a new PC, but I can't remember how I did it!

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.
