My name is graeme , my wife Olivia.

I have many many messages from various people; if I reply to a a mail from "fred", Thunderbird creates a mail:

to: fred@xxxx from: graeme@xxxx

I have several messages from my wife , that behave in this same fashion (ie , as you would expect) but ONE message, when I reply the message displayed in Thunderbird (ie NOT YET SENT, so no SMTP etc yet involved) says:

(it does NOT have a REPLY-TO header BTW)

to: graeme@... from olivia@.....

...I've search back though my mailbox and all the mails from my wife work as you would expect, bar this one ...AND ONE OTHER that I found:

This says:

from olivia@.xxxx to: company@xxxx, olivia@xxxx. graeme@xxxxx

When I hit reply , it generates a message:

from olivia@xxxx to: company@xxxx, olivia@xxxx. graeme@xxxxx

So the from and to in the reply are exactly the same as the from/to in the initial message (they are not swapped)

So, to be clear 99% of messages are fine, it's just one or two cases where I get this odd behavior.

A bug perhaps:- If I highlight various messages at once (I use shift and arrow) and then I press delete. When i subsequently navigate to any other message I can't read it, instead I see this message until I quit and reload Thunderbird: We're sorry, but we can't display this conversation, because the messages have been moved or deleted. Has anyone else noticed this and, better still, do you know how to work around it. I'm using Unified Folders by the way, in case that's relevant.

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.

Bonjour, J'ai Thunderbird depuis très longtemps et j'ai toujours pris l'habitude de stocker tous mes mails dans le répertoire "Dossiers locaux" qui se trouvait toujours sur un HDD différent de celui ou était installé Thunderbird. A chaque nouvelle installation de Thunderbird, je renseignais le chemin ou était stocké "Dossiers Locaux" et hop en 30s, j'avais tous mes messages archivés depuis des années. Je viens de changer de version de Ubuntu (24.04.3 LTS) et la nouveau Thunderbird (140.7.1 esr), donc comme d'habitude je renseigne le chemin de mon répertoire local "Dossiers Locaux" mais rien ne remonte dans Thunderbird ? J'ai essayé (bidouillé) plein de petits trucs sans succès et je ne m'en sort pas ! Pouvez-vous svp me renseigner ?

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?

Since last night, I sometimes get failure to connect to SMTP Server. This happens not always, but frequently. I'm using 0AUTH 2.0.

It only happens when I try to send s.th. Receiving is ok.

Did anyone else experience this and is there a remedy?

Thanks in advane

The ability to select "Done" for New Contacts is totally off-screen on the right when using part-screen (screenshot2 below). When in full screen only a part of the box is available to complete and entry (screenshot1 below).

I've tried adjusting font size and other stuff in Windows 10, but nothing changed the way the Thunderbird looks in this regard.

I created a Mailing List within an Address Book a year ago. I now need to add some new contacts to the Mailing List . I added the new contacts but could only add them to the Address Book. I now need to copy them from the Address Book to the Mailing List, but can't see how to do so , there seems to be no way to view the two lists side-by-side.

My thunderbird email is broken and I cannot interpret the error message. I found a similar problem at https://support.mozilla.org/en-US/questions/1281109, but I have not been able to follow the solution.

The error message is:

Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) promail.ptd.net failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

When I access my email at ptd.net, using firefox, I can make a full connect. But I cannot connect to email using Thunderbird, which is my preferred email tool.

My hope is to have a dialog in this thread with someone who can walk me through the steps to get thunderbird working. Can someone help?

Well Bugs Are Back In Spades With ThunderbirdTurd!!

With THREE of my Email Accounts (2 Gmail and 1 Hotmail) Thunderbird Keeps Returning Mail To SPAM After I Mark It NOT SPAM!! ...... Over And Over and Over And Over and Over AGAIN!!

I've Contacted BOTH Gmail and Outlook Tech Support, And BOTH Are Blaming YOU Mozilla!!

WTH is Going On??? Fix This, Mozilla ThunderTURD !!!

I'm trying to install Thunderbird on a Macbook - macOS Tahoe 26.2 I've made a donation but Thunderbird won't download.

I did not get any error messages, in fact nothing happened.

I recently had to change my password for my att.net email account. My iPhone and the att web mail have successfully read up to 0936, while thunderbird has only read up to 0922, and I cannot get the new password entered successfully to read any further.

Meanwhile, the sending function also cannot get the new password entered successfully.

This is the same password that now works on web mail and on my iPhone.

Account settings, server settings show the IMAP mail server is "imap.mail.att.net" port 993, username = email address in att.net domain, security is SSL/TLS normal password, Outgoing server default is "smtp.mail.att.net" port 465, same username, SSL/TLS normal password.

Settings, privacy and security, saved passwords locked up the mouse with giant cursor showing, had to close thunderbird via Alt+F4, mouse still locked up with giant cursor, had to close all other windows with Alt+F4, hoping to be able to close this one before rebooting computer.

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.
