Thunderbird Community Forum

Hello, I have experienced an error when I click on the inbox of my domain email address. My email *******@meditationwithjason.com sends and receives mail though Thunderbird with no issues yet I get an error when clicking on the inbox. I attached a screenshot of the notification. Hopefully it's just a small issue I can fix on my own. Any help would be greatly appreciated.

Thanks,

Jason

I've spent many hours on this and please note I do not send many emails with attachments, maybe 1 every few months so I don't know how long this has been happening for as I also have noticed in the last year or more that sending just via Yahoo is getting slower in connecting to the server before sending.

W11 see Troubleshooting info as well.

Yahoo accounts 3, all will receive text and messages with attachments. All good. Yahoo accounts 3, all will send text only messages. No attachments. All good. Yahoo accounts 3 all will not send messages with attachemnts or inserted images. NOT good.

It only happens with Yahoo and not others such as Outlook or Google and only affects sending with an attachment.

I have tried troubleshooting tab and changing port number and a host of other things all failing. I have uninstalled Thunderbird and and deleted all %appdata% Thunderbird folders. I reinstalled Thunderbird and created just one Yahoo account with known credentials, no importing nothing. Just an empty account, and it automatically dowloaded confirmation, so account works. I tried sending a message with an attachment and it just kept trying to send for over 5 minutes. I cancelled it. I removed the attachment and clicked send, it sent within 30 seconds. I then did the same with an Outlook account and message with attachment sent within 5 seconds.

Error messages: When creating Yahoo account on completion I get a whole bunch of certificate warnings, about 5. I click accept. I also get the 'sending of message failed' 'This message could not be sent because the connection to Outgoing server (SMTP) timed out. Try again. Always fails unless I remove the attachment. I can also get no message as above after 5 minutes of waiting.

I'm at a loss, all others work except Yahoo.

In the past you could only get notifications for the Inbox, which was nice when you'd use folders and server-side filtering to keep most emails out of your inbox. Please restore this option.

Since recently, TB has started showing subfolders twice:

   1. Normally under the main folder
   2. As grey and italic folders under Inbox in the format Mainfolder_subfolder.

Those grey folders do not have a subscribe/unsubscribe checkbox so I cannot unsubscribe from them. Does anyone have this problem and know how to hide those grey folders?

Ubuntu 24.04.1 LTS Thunderbird 115.15.0 (64-bit)

I get a message that I am unable to sent an email.

because

Login to server smtp.gmail.com with username mariegtirone@gmail.com failed.

I installed Thunderbird and typed in my Office 365 email information to connect my account. Thunderbird found the correct IMAP settings, which I verified on Microsoft's website. It proceeds to open a browser so I can authenticate my account. After that succeeds it starts downloading all of my messages & folders. I thought everything went fine until I attempted to send a message. I get the following error:

Login to server smtp.office365.com with username me@mydomain.com has failed.

It gives me the option to enter a new password, which doesn't make sense since it's oAuth2 but I created an app password to see if that would work, and it didn't. The only other options are cancel & retry which don't help either.

I thought maybe something went wrong with the authentication process so I uninstalled thunderbird and started again with the same results. I've tried many other server settings, but nothing works, so I'm here.

Current Settings:

Server Name: smtp.office365.com User Name: me@mydomain.com Authentication Method: oAuth2 Security: STARTTLS Port: 587

I've tried: Using Port 465 / SSL/TLS Using Port 465 / STARTLS Using Port 587 / SSL/TLS Changing Auth method to Normal Password and then using app-specific password. Uninstall / Resintsall

One final thing to note: I followed the same process with my fastmail.com account, which worked flawlessly. I can send & receive fine.

All was fine with gmail with 128.2.2 for me until this morning. I updated to 128.2.3 and login to gmail imap fails. Backed off to 128.2.2, everything works. Something is wrong with 128.2.3.

PDF attachments to emails are sometimes corrupt. They are not displayed when the email is opened (only a blue line is shown); after they are saved they cannot be opened (Adobe and also EDGE give a message that the file is damaged). The same attachments can be opened and saved correctly using the free Outlook application from Windows. I noticed the problem this month. The installed version of Thunderbird is Thunderbird 128.2.2 esr - but the problem also existed with version 128.2.1.

Thunderbird is getting in a tight loop when I try to print any email.

The hangup is occurring when I execute the print command. The basic dialog appears with the "Preparing Preview" message. The right side of the window appears with only "Print" and the separator line below it.

I must terminate the loop by running the System Monitor and kill the program. If I just close the dialog window, Thunderbird continues to run.

I don't know how to fix the problem. Any thoughts?

This is on openSUSE Tumbleweed. Details follow:

KDE Plasma Version 6.1.5

KDE Frameworks version 6.6.0 Qt Version 6.7.2 Kernel Version 6.10.9-1-default (64-bit) Graphics platform: Wayland

I have had the same problem with older versions of the system for at least a month.

My system is a white box with 16x AMD Ryzen 7 2700X Eight core processor and 16 gb of ram. I have an NVIDIA GeForce GTX 1050 TI/PCIe/SSE2

Thunderbird 128.2.2esr (64-bit) stopped sending emails. It receives OK. This happens in web.com who is my isp. The error message says "Sending of the message failed. An error occurred while sending mail. The mail server responded: Domain Spoofing Prohibited. Please verify that your email address is correct in your account settings and try again." Do you have any idea what the problem is?

I see that part of whats new in this release FIXED = fixed

Some users were unable to log in to Microsoft 365

-However NOW with this version I cannot login.

Please advise

The configuration settings have not changed re: Authorization. Anyone else with this issue? TIA

Canon Scanner issue with Thunderbird using MP network EX 2.0, I have 4 win 10 systems all using LiDe200 and 210 scanners with similar problems, 2 systems I can attach emails to Thunderbird only manually now as the Thinderbird email client isnt shown on the dropdown box only (None attach manually) and the other 2 systems cant send anything at all, comes up with the above and the with a message saying no program is accociated with it, even though Thunderbird is the default email client ............when I try to attached it to an email ............... I have NO IDEA how to fix this and I'm not technically very good either so need answers I can understand and do with out technical jargon I dont understand, I did ask a computer guy who does our systems but he didnt know what the problem was and had no solution for that. I am hoping you can help with it as I'm super frustrated with it, as it came on the back of another Thinderbird issue I have with security exceptions which defies being fixed. HELLLP !

Hi, Please see screenshot. The "From" field does not have my address and there is nothing to select in the drop down. I cannot type into the body of the email either. Also, when I click on "About Thunderbird" I do not get a pop-up window with version. I am receiving email. Thank you Cams

Hi

I recently updated to 128.2.1 esr and my message filters are not working. When I open "Tools" > "Message Filters" the filter list is empty but when I open the msgFilterRules.dat file on my profile the message filters are there. (I made lot's of them.)

Our email accounts are attached to our host domain name. We are going to be changing the host domain location from a smaller local provider to Spectrum Internet to service. The email addresses XXX@xxx.com 'will not change, only the server host location. As a backup, we are moving all existing emails located in subfolders under the email accounts to the LOCAL folder (creating new "trees" there) so they are in a permanent location to be unaffected by the server change. From my knowledge... we will not create new email accounts in Thunderbird .... only change the server location, ports, etc for that specific email. I want to confirm with others that this should be the plan?

Thanks for listening: Last week, Thunderbird began returning this message with each attempt to send mail: An error occurred while sending mail. The mail server responded: <tedcomo@chartertn.net> sender rejected. Please verify that your email address is correct in your account settings and try again. I have no problem receiving mail. At the same time, my wife began having the same problem on her laptop, which tells me either Charter, or Mozilla, changed something. I started with Charter. They told me to rename both servers to mobile.charter.net (outgoing mail was formerly smpt.charter.net. No effect. They then had me log into Spectrum and send a test mail directly from my account. It went through OK and they said the problem had to be on Mozilla's end. Any suggestions?

SOME EMAILS CAN BE MOVED TO FOLDERS. LARGE NUMBER OF EMAILS SOMETIMES CAN BE MOVED TO FOLDERS. THEN, ALL EMAILS MAGICALLY APPEAR AGAIN. WHAT GIVES? IS THERE A SPECIFIC SETTING THAT IS CAUSING THIS GEM?
