Thunderbird Support Forum

I just noticed that if I check the SENT folder, some of the emails I sent have this text in the body part.

"This is a multi-part message in MIME format.

Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 8bit

[HERE THE CONTENT OF THE EMAIL I SENT]"

I'm wondering if they are sent like that, what the receiver will see and if there is a way to prevent it.

The email account is using IMAP and as far as I know it happen just to that specific email account. The emails are sent using Thunderbird. I'm using the latest version of Windows on a laptop. I'm using the following Thunderbird extensions (latest versions): - Compact Headers - Send Later - Mailmindr - Quicktext

This is a recent issue. If I send an email with no images and no attachments, it copies the email into my "sent" folder with no problem.

If I send an email with even a small attachment...it sends the email, but "times out" copying the message to the sent folder.

I've checked the account/server settings, they are exactly as recommended. I've changed the sent files to "other"...no difference. I deleted and reinstalled Thunderbird...no change.

Ideas?

I opened Thunderbird this morning and there were no issues. Closed it and just now reopened and I'm getting this message: Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

It downloaded 28 emails but will not let me see/access them.

Can anyone help? Thanks, Linda

There is an email app provided by xiaomi on my phone.What in the email sent by this app contains a special format of `Date` fields.It looks like that: `Date: Thu, 2 May 2024 05:55:12 UTC` It doesn't look like others' `Date: Thu, 2 May 2024 06:05:15 +0000` or `Date: Thu, 2 May 2024 10:35:14 +0800 (CST)`

but it is still conforming to standards (or is it only parsable by the JavaScript Date method?)

After I modified windows time zone and restarted thunderbird. all emails changed time so this is not a time zone problem.

But this email shown two different times in the preview and detailed pages at this moment.

So can anyone tell me if this is a bug? Thank you.

I am unable to copy text and paste from body of email in Thunderbird. I was able to in past versions. When I right click after highlighting text all options appear but does NOT allow to copy anything.

For many years, my wife and I have each used Thunderbird on our own computers. Several weeks ago, when my wife turned Thunderbird on, a new screen appeared that mentioned account setup and directed her to set up her existing email address. When she did, a home screen appeared that was significantly different than the one she had been using. But more than that, she lost all her saved emails and Thunderbird started to reload emails. The reloading ended with over 1800 “new” emails whose dates reached back for almost a year. Since then, after some work, the home page has been returned to its earlier look; downloading, sending and deleting are working as before. Missing are a few important, personal subfolders. We’ve tried a few things that we thought/hoped would return us to the point before everything went crazy. That hasn’t happened. Recently, we looked at the Profiles folder on each of our computers and saw something that, I think, is unusual and, I hope, might provide a way get her back at least some of what was lost.

The route to my Profiles is C: > Users > Me > AppData > Roaming > Thunderbird > Profiles In Profiles are two folders, one ends with .default and the other with .default-release. The only thing in the default folder is the file times.json. The default-release folder contains many files and folders, including the Mail folder. The Mail folder contains two subfolders: Local Folders and mail.comcast.net.

On my wife’s computer, there is only one folder inside Profiles. The name ends in .default. Inside that folder is the Mail folder. Within the Mail folder are six subfolders: Local Folders, Local Folders-1, Local Folders-2, mail.comcast.net, mail.comcast.net-1, mail.comcast.net-2. The Date Modified date for Local Folders is probably the date the problem started. Date Modified for Local Folders-1, mail.comcast.net and mail.comcast.net-1 is the same: a few days after the date for Local Folders. The dates for Date Modified for Local Folders-2 and mail.comcast.net-2 are the same, and change daily.

I’m hoping/assuming that the missing, personal subfolders are in one, or more, of Local Folders, Local Folders-1, mail.comcast.net, mail.comcast.net-1. What I’m asking here is: does anyone know of a way to easily locate and recover the subfolders and, then, move them into the correct location in Local Folders-2and/or mail.comcast.net-2.

Thanks for taking the time to read this long story.

trying to get email - got this error; How do I fix this?????????? Happening last few days.

my email: [edited] @yandex.com

Sending of password for user pizzipie did not succeed. Mail server pop.yandex.com responded: [AUTH] login failure or POP3 disabled, try later. sc=75IVcg0DLKo0_290005_

Recently, when I click on Get Messages to download email from Comcast server I receive error messages. One error shows "Login to server mail.comcast.net with username X?X?X failed. Retry, Enter New Password, Cancel".. Second error shows "Sending of passwowrd for user X?X?X did not succeed. Mail server mail.comcast.net responded: [AUTH] Temporarily blacklisted IP Address - try again later" I spoke with Comcast tech support and they, of course, gave me the standard line that I was using a 3rd Party App for email and they could not support that and I could instead use the email on line at my Comcast account site utilizing the antiquated Comcast mail options. They finally attempted to help and after they researched the issue they suggested I change the Server Name setting form 'MAIL.COMCAST.NET' to 'IMAP.COMCAST.NET' and changed port from 995 to 993. I tried making those changes and was not receiving the error statements. But I also was not seeing ANY email downloaded or message indicating TBird was login in the Comcast server. I then changed the Server Name back to 'MAIL.COMCAST.NET' and port back to 995. TBird then correctly downloaded dozens of emails. When I tried to same thing the next day, though, the error problems had returned. Finally, I was looking at Tools>Account Settings and selected Add-ons and Themes in left pane. I noticed Bitdefender Toolbar was enabled under Extensions so I tried switching it to disabled. Voila, the program would once again download emails. But a short time later another try to Get Messages resulted in the errors again. Can anyone answer with changes to connect properly to Comcast for email? Any help would be greatly appreciated.

As stated in the subject, Thunderbird Beta will not close properly, leaves 4 remnant tasks in the Windows 11 task manager that I have to close manually before I can open the program again. This started with this last beta, prior one worked properly. Please advise on what further information I can provide so this bug can be fixed.

I have Thunderbird 115.9.0 64 bit on the 2nd latest version of Ubuntu Linux and by second latest I mean it is still supported even though there is a new version available. Several months ago there was a password problem with my internet account preventing me from logging into my internet/email service and all my devices could not send or recieve emails. I changed my password on my cell, my Windows 10 computers and they worked fine. My Thunderbird on my Ubuntu on the other hand rejected my password and I also checked all of my port and server settings with the help of my internet service provider tech support including comparing settings from other email clients. Still no password being accepted. My internet/email service provider tech agent suggested removing my account from my client and reentering it and this worked.

Several months later I changed my main email passwords again on incoming mail and outgoing mail servers on my account, verified my port settings are correct, which they were including the type of security and protocols used. When I select the desktop icon I get prompted to enter my main password and hit enter and the window keeps reoccurring as if it has rejected my password. I select cancel allowing me to enter and again clear and reenter password and again it is rejected. I removed my account (I think) and go through the motions of reinstalling my account and get a pop-up indicating the server already exists which puzzles me. Ports, security settings, password are all correct and tested on other devices. I can even use a browser and log onto my internet service providers server and access my account and my password works but not on my Thunderbird. Should I consider uninstalling and then reinstalling my Thunderbird on my Ubuntu? I think by mistake I deleted all of my emails BUT I have selected IMAP so my emails I want are still on my service providers server. IF I uninstall and reinstall how do I save my contact list. This I Inoticed is still intact. Suggestions please?

I've been noticing apparent duplicate messages within my unified folders inbox on my desktop recently.

Looking further I notice that one of my accounts has 'INBOX' as one of its subfolders which is where the problem appears to stem from. When I look at that account in isolation (ie not in unified folders) I can still see the inbox as a subfolder.

The subfolder 'INBOX' appears to be a duplicate of the account's main inbox (it contains the same number of emails), which may account for the appearance of duplicates.

At a guess this is probably related to inadvertent moving of folders. I find that when trying to use the scroll bar (to scroll down the subfolder list), if the mouse strays slightly to the left it will pick up a subfolder and move it unintentionally. This can cause all sorts of problems with disappearing emails and the folder structures showing differently on different computers.

In this case the duplicate email problem only happens on my desktop. On my laptop I can still see a subfolder named 'INBOX' but it shows as empty and I don't see the duplicate emails in unified folders.

It would be really useful if Mozilla could introduce a 'confirm folder move' feature as that would eradicate inadvertent moves.

How do I resolve the apparent duplicate emails on my desktop? I am somewhat reticent to delete the subfolder 'INBOX' for fear of the potential consequences. . .

Hi, from this morning I get an error message in my Thunderbird "Login to server . . . with username . . . failed" to my old email addressed. In "Server Settings" none of the "check for new messages" is marked. I have used this setting for long time, but now I receive an error message every few seconds and cannot work. I was with TB115 and updated to the newest version, with no avail. many thanks for your help Shaul

Upon reopening Thunderbird mail today, I find that the latest update does not allow emails to be opened in a new window with one-click. Clicking on an email launches the message in a new tab instead of a window. Why create a new issue like this? DUMB . . . please fix.

I cannot send emails from thunderbird-times out. I can send directly from outlook. I removed the smtp from thunderbird in case the file was corrupt. I replaced it with the exact settings from outlook but it still won't work. I have to use outlook directly to send messages. I get all emails in thunderbird (imap) My outlook settings which I duplicated exactly in thunderbird are; smtp-mail.outlook .com Starttls Normal password Thunderbird times out after 1 minute for a message with only a subject (1 word). I have 300 megs/second so it is not connecting. It worked fo 5 years but now it does not. Please help!

Lately, I noticed that TB is quite slow at loading messages so I looked up for a solution and found that compacting folders could help a bit. The problem is that when I tried to compact some folders TB started to write hundred of GBs to disk completely filling my ssd and ultimately failing with a 'not enough disk space error'.

I don't think this is supposed to happen. Can I fix my inbox or should I start from scratch?

Hello, The scrolling speed of the different toolboxes in the software became much too fast with the pad on my computer (Zenbook 14"). It didn't do that before the last update. Am I the only one? I lose a lot of time every day with this bug.

Thanks :-)

The last auto upgrade included a calendar function, which I switched off as I thought this was causing the problem. But now after all the messages have downloaded, I get the usual pop-up box in the bottom right of the screen telling me I have received x messages but it only half fades in and the whole PC jams. CTR-ALT-DEL does not work and I can't switch to a different window or even click on anything in the Thunderbird screen. The only thing that I can do is hard reboot the PC and switch off the router, which allows me to start up Thunderbird without anything downloading. I am using Windows 7 and Avast as my AV. Any help would be gratefully appreciated.
