I have just installed Thunderbird on a replacement computer (running Linux Mint). The version I have is 140.7.1esr. I use a POP Gmail account. For a change it installed and connected seamlessly, but I cannot persuade it to download anything other than the messages in my Inbox. I have right clicked as recommended on my Gmail address, but see no 'Subscribe' to select. What am I doing wrong?

Yesterday I found that I can't send mail using Yahoo.ca. I was able to get my wife's computer working by sending an email. A message came on the browser and I logged in to Yahoo. She can now send email. When I tried the same thing on my computer, I get a message "No apps available". I have spent hours trying and can't get around the message. The simplest test is as follows:

• create a new profile, and open the new profile
• enter my name and email address, and continue
• I get a message "Configuration found in Mozilla ISPDB." It uses SSL/TLS and Oauth2
• I hit next. Yahoo opens a page in my browser to log in. I enter the password and the security code sent by text
• The browser sends a message to allow an app. When I allow it the message "No apps available" appears as shown.

The release notes on Thunderbird are Version 153.0 | Released July 21, 2026 For now, I can use a second account on gmx.com to send mail, but prefer to use Yahoo when it works. Any suggestions?

family and friends, communities sending info directions to my Inbox and I'm not receiving these emails. We always compare if I gave them the right email address. I need help to correct the problem.

I have thunderbird installed on my PC, and my main email account is a gmail account. I download from gmail using POP protocol (SSL/TLS connection security, OAuth2 authentication). I have been using these settings for a long time (15 years?).

This afternoon, thunderbird stopped downloading my messages. No error messages : just "no new messages to download".

I can see (by logging directly into my gmail account using my browser) that there are new messages on the server. They're not spam or junk, and they're not getting downloaded into my (local) spam folder. They're not getting downloaded at all.

I still have room on the google server (it's about 87% full), and room on the hard drive on my computer (about 3 GB).

I use Windows 10 and Thunderbird for email but I can NOT SEND anymore to anyone. I got an error message that said, "Authentication Required" and gave me a web address go to but google says it no longer available. Tell me how to fix Thunderbird so I can SEND messages again..

My email provider sometimes fails to send mail, so I find the mail that didn't send in the sending box (发件箱; I don't know the name in English), use the "edit as new mail" option in the mail 3-dot menu (there's a pencil icon on the top of the screen, but it has no reaction) and tap send button again. I find that every time I do this, the mail's sender identity is reset to the default identity.

I know my Thunderbird version is not latest and is beta, but I'm hesitant about updating. Is it a bug or designed behavior?

Steps to reproduce: 1. Turn off your device's network. 2. Compose and send a mail with an identity that's not the default. 3. Find the mail in the sending box, and choose "edit as new mail". 4. Hit send button. 5. View mail in sending box, it now uses the default identity.

Have used Thunderbird for many years - very pleased - just got a new laptop - in the past, an email sent or received from the phone was visible on the laptop - and vice versa - with the new laptop, I cannot see email I have sent on the phone - also, while on the phone I cannot see email I have sent on the new laptop - I really want these messages synchronized like they were a month ago - what do I need to do?

This month I downloaded the current version of Tbird on a new computer running windows 11. Tbird receives all my email but can not send mail. I have an old computer running on windows 7 which has Tbird that was loaded at least 5 years ago. It receives and sends email without problems. The two versions of Tbird are using the same SMTP settings: server: mail.twc.com Port: 587. My email account for Tbird is xxxx@triad.rr.com

I also have a gmail account which receives and sends on both computers without problems. My gmail account is xxxx@gmail.com.

Both computers run through the same internet network.

I get this message when I try to send emails Sending of message failed. An error occurred while sending mail. The mail server responded: mf-505: Sender Policy - Relay Denied. Please verify that your email address is correct in your account settings and try again. How to I find out this information

How to avoid: Sending of the message failed. An error occurred while sending mail. The mail server responded: message rejected .

AUP#SNDR. Please check the message and try again.

Consistently Reproducible.

I have smtp.gmail.com set up as my outgoing server (port 465, username = my gmail address, Authentication = OAuth2, connection security = SSL/TLS, also tried STARTTLS with port 587). There doesn't appear to be any way to set the password in the "Outgoing Server (SMTP) Settings", even when I click "Edit". Nor can I add a password to the "Edit/Privacy&Security/Saved Passwords" dialog box (which allows you to see existing passwords or remove them, but not add any).

When I try to send an email, the "Sending Message" dialog box pops up, and after a few seconds a second box pops labeled "Login to account 'smtp.gmai.com' failed". This box has three buttons: "Enter New Password", Cancel and Retry. Clicking on the "Enter New Password" button does not offer me the chance to enter a new password--instead, it immediately takes me back to the "Sending Message" box, which then immediately takes me back to the "Login...failed" box. There is never an opportunity to enter the password!

TBird 140.7.0esr, Thunderbird for Linux Mint. Mint version 22.3.

Sending works ok if I choose a different SMTP server.
