Thunderbird-Hilfeforum

If I view an old mail, and if the remote contents are no longer available in the server, then I cannot know the contents. Whatif Thunderbird downloads the contents (when the email is downloaded) and includes them in message itself?

Hello,

I have been using Thunderbird for years to collect all emails in one place with out issue. In the last few days authentication has started failing. It started on one gmail account prompting for a password. When I enter the password it is rejected. A second GMail account is now doing the same and one of my Yahoo accounts is now doing it too.

I can still access the accounts on my phone using Oauth2.

Nothing I have tried fixes it. I am in danger of losing access to all my of my email accounts on windows.

What is going wrong?

Several days ago TB daily started asking for my ATT(Yahoo) password. TB initially rejected my password but I did "forgot password" and added exactly the same password back since it was working on ATT(Yahoo) web mail. Now I get "Sending of password for user xxxxx@bellsouth.net did not succeed. Mail server inbound.att.net responded: [SYS/TEMP] Server error - Please try again later." TB continues to ask for my password but returns this same message. I looked up the saved passwords on TB settings, but don't recognize any of the passwords. They look like eOauth passwords, but I have never set this up. There are no listings for att inbound or outbound servers. I have searched all the Support articles but cannot find anything that fits this situation. I am thinking something is corrupted on TB and I may have to delete this account and reinstall TB. BUT, I don't want to lose all the emails I have stored on my computer. I copied the Thunderbird file and saved it in another location just in case. 1. Any ideas on how to get running again? 2. Another option might be to delete all the TB saved passwords and put them in again when requested, but will that screw up other stuff? 3. If I have to delete the account and reinstall, how do I make certain all of the emails come back? Thanks Shaw

I changed the password of one of my emails when trying to configure it for my phone. I forgot that it was set to 0auth2. So now I have changed the password and can open the Gmail, account online OK, but I can't find how to go back to the 0auth2 password. 0auth2 is still set in Thunderbird but I have no idea what the old 0auth2 code was. How can I update it to work again?

After upgrading on my Mac Pro 2010 to Thunderbird 91.10 I couldn't access my Google account. I found some suggestions (e.g. change to 0auth) - and eventually am able to receive e-mails. I still can't send them - not even when I went back to 91.4 (when I could send e-mails). I am being asked the password for my Google account, but when I fill in the correct one, I am again asked for my password - etc. I use the correct one as evidenced by the fact that I can access my Google account via Safari. I have contacted Google One. I followed their suggestion to accept Thunderbird on my Google account. I still can't send e-mails. Google One just now suggested that I no longer use Thunderbird as it does not seem to satisfy their safety standards. I don't want to do that (I like the lay-out). The alternative is to cancel my Google account. Please help: what is wrong - or if I am to blame, what am I doing incorrectly?

I want to connect one of my Gmail account using OAuth2 and I face a blank page after accessing the Google connection page and entering my email address. It only happens on this account.

I have no issues to connect other Gmail accounts, and I tested 4 of them. Is there a way to know where does the issue come from and/or how to solve this? I already applied everything advised in https://support.mozilla.org/en-US/kb/automatic-conversion-google-mail-accounts-oauth20, to no avail.

Checking the servers and domains that are connected by ThunderBird was a horrifying experience:

incoming-telemetry.thunderbird.net aus.thunderbird.net thunderbird-settings.thunderbird.net live.thunderbird.net services.addons.thunderbird.net versioncheck-bg.addons.thunderbird.net versioncheck.addons.thunderbird.net

location.services.mozilla.com

Are you crazy?!? Totally?

I am using Mozilla products for PRIVACY and SECURITY !

I don't want to be collected for telemetry and location! And also for nothing else that is not ESSENTIAL for using the App!

1) Please explain for which reason any and all of the above servers get connected Esp. what is "aus" for and "live"? What does the "settings" host is used for? Why are there 2 "versioncheck" servers?

2) Please FIX this list by removing any and all statistic-collectors like for telemetry and locations! And also by removing other, non-essential hosts!

Thanks!

This is an ongoing problem and it has been around for years. I know it existed in 102 and also now in 115. That is that despite the Junk Settings being set to "Delete them" under the checked statement "When I mark messages as junk", they do not ever get deleted. I have to manually delete items marked as junk, which is mostly accurate. So in my inbox, I just see a multitude of items marked as junk each morning until I re-sort by junk status instead of date and then easily delete them and then go back to sort by date.

In TB 115.1.0 (64-bit) on Windows digital signature are maked as not valid for an unknown reason. This happens at least with emails send from Outlook clients. In TB 102.14.0 (64-bit) on Windows this digital signatures were shown as valid. However, digitsal signatures of emails send from other clients (e.g. Thunderbird, Nine from 9folders) are shown as valid.

Outgoing email includes the user-agent header. I would like to disable or modify the string for better security.

User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:91.0) Gecko/20100101 Thunderbird/91.8.0

Thanks...

My thunderbird configuration uses POP to download email onto my local computer. I recenly became aware that evrytime I read an email I have received from Constant Contact, Constant contact is being sent and report of my access that email. That is not refering to when the email is downloaded. After I download the message, Constant Contact is notified I have open the email. This happens just by opening the email, no links in the email have been clicked. I have the sending of return receipts turned off, but this seems like something different than a return receipt.

I suspect this is related to some of the tags I see in the email: X-Campaign-Activity-ID, X-Channel-ID, X-Feedback-ID, etc.

I am sure the marketing people on the other end love this, but to me it is an invasion of my privacy. Is there a way to prevent this in Thunderbird? It seems to me to be a no-brainer that email users should be able to prevent such an intrusion into their privacy. Am I wrong on that?

I must admit that I was very upset when I discovered some time ago that permissions for my files and folders in .thunderbird were messed up in a way that had given all files permission to run as programs. Now I have been living with it for a while without disaster, and I found out the reason for it is that I used ntfs format instead of ext4 on my backup disk. However it still feels bad, and I still don't know how to fix it correctly.

I have for many years before used Fat32 for my backup, .thunderbird included. And it looks like Fat32 takes all those permissions away, so if I just do that again and restore, the illness in quest will be cured. There are some symbolic files I can't copy to Fat32 but Thunderbird doesn't seem to care. Could that be a good way to fix it.?

Or can I perhaps expect an automatic update eventually will fix it.?

Or how do I fix it correctly.?

Thank you in advance.

I originally installed Thunderbird about 2 years ago via the package installer on my Linux desktop. Currently running the 68.10 version which has never updated nor is there a function to update the program. I've read through the FAQ's and nothing was helpful. This all came to my attention when I received the following email from my email provider at mail.com a few days ago.

"Deactivation of TLS 1.0, TLS 1.1 and unencrypted access We are contacting you because one or more of your devices or programs uses the TLS 1.0 and/or TLS 1.1 encryption protocols to connect to our mail.com email servers, or is using an unencrypted connection. This involves either access via SMTP (sending emails) or retrieval via POP3/IMAP (receiving emails).

Unfortunately, the TLS 1.0 and TLS 1.1 encryption protocols are outdated and no longer meet current security standards. To protect your email communications, soon we will no longer allow access to our mail.com servers with these outdated protocols. Unencrypted access will also no longer be possible."

They indicated that mail service will stop to my Thnderbird account in a couple weeks if the problem has not been corrected.

Thank you for any suggestions about correcting the issue.

Hello,

Ive installed a MIME-certificate from Sectigo in Thunderbird 115.6.1 on Pop OS (flatpak).

The cert is in a pw-protected .p12-file which I have imported successfully. However when I try to sign emails I get the error-message shown in the first attached image. That the application cant find my cert or that it has expired. Both statements are incorrect imo :)

In attached image 2 and 3 it shows that the application has imported the cert and that its valid until 2025.

Any tips or input is helpful.

Also under Security Devices I have a PKCS#11 module that I have logged in to, but I dont see how that could affect PKCS#12 certs but I read in some guide that I had to do that. Which also apparently mean that master password is set for protecting credentials in the application, so I have to provide that password when opening Tunderbird.

Setting up a desktop (Dell Inspiron) for neighbors using latest Linux Mint (21.3 Cinnamon). They have simple needs, LibreOffice, Firefox and email. Plain jane, nothing extra added, straight from latest Mint install.

I am having trouble adding a second email account in Thunderbird (115.8.1). First comcast account was very easy, standard comcast defaults, works fine, downloads and sends. Second comcast account keeps giving "Unable to Connect" poput screen. (https://localhost/?code=0.ac.w2.PciwTw)

I can login to either Xfinity email account through Firefox browser using same addresses ((username)@comcast.net) and passwords I am using to attempt to add second account in Thunderbird.

Tried it with Mint Firewall off, then on, then off again. Do I need to setup firewall for second account?

Can someone give me a hint on this problem? Is is Thunderbird? Comcast? Something else?

I did a clean install for my PC, Installed Thunderbird, added my mail account, checked "save in manager" after entering my password. After restarting the prompt keeps appearing after starting. The Password Manager has no saveds passwords.

I tried deleting cert9 and key4 and session.json, none of those helped.

Recently my Thunderbird started asking for my passwords every time I opened it (I have multiple Hotmail accounts). After I added the passwords it would keep asking for them over and over again (they were ALL correct). I have now uninstalled and re-installed the latest version of Thunderbird and only added 1 account back in and it still keeps doing the same. The password is visible and correct in the saved passwords section. I am now having to use another client (Outlook,which works correctly, but isnt a patch on Thunderbird) Running MACOS 12.7.3 Any help would be greatly appreciated.

Hello, I am stuck in an unsolvable loop. I recently upgraded from version 38 to 102.x. I can not set a primary password. I can not set any other passwords. I read several articles, reset my password, etc. Instructions can be difficult for me, unless explicit. I would appreciate help. TY. Vince

Primary password not set. Unable to change Primary Password.

Hello, I'm afraid TB stopped working after I changed my gmail password. Whenever it tries to connect to the imap server, I get the oauth login prompt, fill out the password, confirm that I want to allow TB to access my gmail account, but after that, I just get the "Authentication failure while connecting to server imap.gmail.com."

I have OAuth2 set as the authentication method, I have cleared the saved passwords, updated TB, manually deleted obsolete files in the profile folder and basically tried every advice I could find, to no avail.

All worked well before the password change (the big end-of-may less secure app business did not affect me).

Currently, I have removed all my gmail accounts from TB and am trying to add them again. One of my gmail account uses 2FA, in this case, I also tried to use the app password. The other gmail account does not use 2FA, so I just used the regular password. In either case, I get the popup asking me to allow TB to access my mails, which I provide, but end up with "Unable to log in at server" message.

Any help would be greatly appreciated.

After update to 102, TB is asking for a PW when starting in normal mode. -> PW-vault is empty When starting in safe-mode everything is working well. (PW-vault is not empty)

I tried to make a new profile. Then it worked, but only until next update (102.0.1).

This happend also after update to 102.0.2 and 102.0.3. :(

Now I tried to copy a not working profile folder from mounted NAS-drive to local drive. -> Profile on mounted device is working only in safe-mode -> Profile on local device is working well in normal mode

For me it looks like, TB is not able to read (decrypt?) stored PW from mounted devices in normal mode. (But it works well in safe-mode).
