I am using Protonmail with Thunderbird. In my Protonmail web account there is nothing in ANY folder but the very few I am currently keeping, including All Mail. The same folders and messages are represented in Thunderbird folders. However, in C:\Users\username\AppData\Roaming\Thunderbird\Profiles\wiu0xbpg.default-release\ImapMail\127.0.0.1, the All Mail folder contains all previous messages, including deleted messages, are still present. When I delete a message, I want it deleted. As can be seen in the attached image, All Mail is very large whereas all other folders are very small. 1. How can this be cleaned up? 2. How can this be prevented in the future? Thanks for any direction in this matter.

As stated above, received msg from me to me -- a common practice I hear. If I change my password, will that fix this? I tried to log in to Outlook on line to change password but I use a passkey - doesn't let me do a password entry. Help..... Thanks.

good day....ii hope someone can help. the other day i was accessing my yahoo account spam folder and by accident, i deleted the spam folder instead of emptying it. the spam folder is now sitting in the trash and i'm unable to remove it from there. when i log into my actual yahoo account, the spam folder is where it's supposed to be and not in the trash. i tried removing the yahoo account from thunderbird and reinstalling it in hopes that it would rectify the problem, but it hasn't. does anyone have a solution?? i would greatly appreciate any help you can offer. thank you for your time...mike s

Thunderbird 143.0.1 eclipse.

Quite recently I noticed that, in the list of folders, I see 2 "Junk" folders.

On looking at the properties for 1 Junk folder the location is shown as "imap://*********%40gmail.com@imap.gmail.com/Junk",

but properties for the other shown as Junk locates as "imap://*********%40gmail.com@imap.gmail.com/Spam".

I've tried renaming that folder in Thunderbird to Spam but the change doesn't take effect.

What went wrong, and more importantly how can I rename it to see it as "Spam"?

tnx.

Walmart has abandoned passwords as 2nd id check. now they send email. I've requested re-send about 8 times. Still not appearing in my mail. How can i find if T=bird is filtering out ? Once I think I saw a notice show up for about 1/2 second and then it was gone.

I am using Thunderbird 147.0.1 connected to an Exchange 365 service using web access. All folders except Junk are listed on the left hand pane and are synchronising to local storage.

When I go to 'Account Settings', 'Synchronisation and storage, 'Advanced' the Junk mail folder is not listed as available for se;ection.

How do I enable the junk folder to be available locally? Many thanks for ant assistance.

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?
