Enclosed are jpg copies of the current sets of filters failures in my TB email program.

TB Error0 shows the 6 emails that have arrived and are placed in the INBOX. However, each of these has a corresponding filter set up to move them upon arrival to a separate subject email mailbox.

Note: If I highlight the INBOX and then go to Tools > Run Filters On Folder ... all of these INBOX email messages will be correctly filtered and moved to their respective email mailbox, BUT each of them is shown as having been "read" and unless you pay close attention, you may not know where these INBOX emails were sent.

I am also enclosing TB Error1 & 2 that show the last couple of days message filtering errors.

I can find nothing wrong with how each of these filters are set up, yet they seem to consistently fail to operate when new emails arrive.

Note one of them is for incoming emails from ... schiffsovereign.com. I have edited this filter repeatedly, even deleted it and re-input the information. Yet the filter never takes hold and does what it is designed to do. I am enclosing a jpg of that specific filter as TB Error3

I am looking for suggestions on how to fix this problem.

Thank you and best wishes,

I am trying to send an S/MIME encrypted email from Thunderbird to:

jobcenter-chemnitz.netzwerkpartner@jobcenter-ge.de

The recipient certificate is provided by the official certificate directory of the German Federal Employment Agency (Bundesagentur für Arbeit).

I downloaded the recipient certificate and successfully imported it into Thunderbird under:

Settings → Privacy & Security → Certificates → Manage Certificates → People

The certificate is displayed correctly there. The email address contained in the certificate is:

jobcenter-chemnitz.netzwerkpartner@jobcenter-ge.de

The certificate is valid from July 29, 2026 to July 29, 2028 and includes E-mail Protection and Key Encipherment.

The required CA certificates are also installed:

BA-Class-1-Root-CA-4:PN BA-VPS-CA-11:PN

However, when I compose an encrypted email to this exact address, Thunderbird reports:

“You have selected to encrypt this message, but the application failed to find an encryption certificate for jobcenter-chemnitz.netzwerkpartner@jobcenter-ge.de.”

Under S/MIME → Recipient Certificates, Thunderbird also shows the certificate as “Not found”.

I have already tried:

deleting and re-importing the recipient certificate completely restarting Thunderbird after importing it manually typing the recipient address in lowercase without using autocomplete checking the complete CA certificate chain temporarily disabling OCSP

None of these changed the result.

My own personal S/MIME certificate works correctly. As a test, I can compose an encrypted email to my own email address without any certificate error. Therefore, the basic S/MIME configuration and my own certificate appear to be working.

When I reproduce the problem with the Thunderbird Error Console open, I get:

NS_ERROR_ILLEGAL_VALUE (0x80070057)

related to:

nsIMsgComposeSecure.beginCryptoEncapsulation

This seems similar to Mozilla Bug 2021265, where a manually imported recipient certificate is visible in Certificate Manager but is not found when composing an encrypted message.

Is this a known issue in Thunderbird 140 ESR, and is there a workaround for using this manually imported recipient certificate?

My email was rossmann@telkomsa.net My husband died on 25 May 2023 and telkom closed his account. I opened a gmail account. I am now wanting to open a few emails from 2022 regarding contracts but Thunderbird obviously only has my old email. Please could you assist me Kind regards, Chrissie Rossmann

Hello,

Everything working just fine last night. Wake up and Thunderbird will not retrieve emails.

Remembered this old message I got so I went through and deleted my second email address, didn't help.

https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo

Checked all settings compared to Yahoo, still won't download messages. I can even send a message with my current settings no problem, and it does login, just won't retrieve emails. Gives me a connection timeout.

Anyone have any ideas?

I have a filter setup to forward certain emails to another account. It has been working fine for years. Suddenly today I am getting an error message about not being able to contact the smtp server. If I manually forward the email to that same address it goes fine.

Guten Tag, wie kann ich Einträge in "Täglicher Spambericht Mailbox....", wieder herstellen. Es wird immer nur die Mailadresse des Absenders angezeigt, nicht die Nachricht. Danke für eine Rückmeldung. MfG. K. Artschwager

I'm trying to upload less than a gigabyte of images to my send storage but am getting the following error: "you don't have the key to decrypt this container"

This is my own storage space.. I've already generated my own key. Why would it be saying this? I see there is also supposedly an option to upload/share files via send natively in thunderbird via a dropdown menu from the "attach" menu, as show here in the list of features. However, this option doesn't appear in my thundermail. Yes, I've installed the Thunderbird pro addon.

What is happening...

Hello, I'm a user who's blind, of course as per the accessability topic I selected here. I need help with thunderbyrd and reaching back to the messages list from either a message body and/or now currently, from the settings pane. I've tried the following: 1. Hitting F6 to figure out where the message list lies within the cycle of panes, but all I get are the search pane and the reading pane main region. 2. Tried hitting tab from the spaces menu when I find the mail as alt 1. 3. Just going back into that tab, the mail, and nothing works. I still end up back in the settings currently but was in a message body before. No matter how I turn off thunderbyrd and reopen it, this is still happening. I use NVDA only for games/current screen reader in use, but I mainly use JAWS for Windows, which is on its latest updates. NVDA is as well. Is there anything you can suggest or should I just use the outlook new from Microsoft, which I still have but it's a pain to use with screen readers. Thanks soo much, Ashleigh P

I apologize for the subject line, but there is no better way to describe the problem....

I've been using Thunderbird for a few months now and it has mostly worked well. Then this afternoon I was reading my mail in the Unified Inbox and I noticed something very odd. I had a number of emails showing in the header list with the same "From" and various subject lines. On the face of it, that wouldn't describe any weird behavior except that I noticed the subject lines absolutely didn't match the "From" information.

As I would go to read these emails, the email itself would be correct in the preview pane -- including showing the correct sender name and email -- but the "From" information in the header list pane would still be wrong.

I'm sorry that I can't post a screenshot to make this more clear because there is just too much personal information on screen. But these emails are from several different senders, received by several different email accounts. Everything is correct except that the "From" shown in the header pane is wrong. This is very obvious to me because I normally run entirely in the Unified Inbox with the emails sorted by the "From" information

One example is an email that is actually from "U.S. Department of Veterans Affairs <do-not-reply@notifications.va.gov>" which Thunderbird displays correctly in the preview pane (where I usually read my emails) and if I open the email itself, but the header pane says this email is From "Prepper-co <joshua@prepper-co.com>"

Another example is an email that is actually from "USPS Customer Support <uspscustomersupport@usps.gov>" but the header pane says it is from "Rainier Arms <sales@rainierarms.com" < p></sales@rainierarms.com">

These two examples were received in different email accounts that aren't even on the same server. I have other emails from these same senders that are shown correctly

I found this problem while using 150.0 (64-bit), which said 150.0.1 was available, so I restarted Thunderbird and it updated to 150.0.1 (64-bit) but the problem is the same.

When I try to send a email from my secondary account I get the following error: A unique identity matching the from address was not found. Message will be sent using the current From field and settings Identity. In other words my main account sends a message to my secondary account. When I try to use secondary account I get the error message. The secondary account does not work now.

For the past 30 years I have had an e-mail account with FreeNetName in the UK, which during that time moved to Madasafish and then PlusNet.

I have always run the account on Thunderbird as POP3.

I've just moved the account to GoDaddy and set up an Outlook e-mail account with them.

I'm unable to set up Thunderbird on POP3 or IMAP to be able to access my e-mails, despite having followed numerous articles.

When trying to complete set-up, I get the error: "Configuration could not be verified. If your username and password are correct, it’s likely that the server administrator has disabled the selected configuration for your account. Try selecting another protocol."

Within the Outlook settings, the "Let devices and apps use POP" slider is greyed out.

Has anyone else had this issue?
