How do I access my e-mail account;jrltique@goldrush.com? I have had this for many years and just got a new computer and am totally lost! I always logged onto Mozilla \thunderbird!

I installed thunderbird for Windows on PC all was good till it went looking for a outgoing server a red box popped up and said outgoing server is already installed . That ended the install.

Sending of the message failed. An error occurred while sending mail. The mail server responded: <support+idMM51X2-RWD3K@dealerbuilt.zendesk.com>: Relay access denied. Please check the message recipient "support+idMM51X2-RWD3K@dealerbuilt.zendesk.com" and try again.

the above is the error code. I have triple checked emails, even tried sending a message to my personal email as a test and nothing.

When selecting which email account to send FROM, the drop down shows a number of old email accounts. These accounts have been deleted. There are no details showing under the "account settings" or "Outgoing server." Which file stores the mail server information and where is it? I currently have around forty different email accounts across five mail servers.

Best regards

From the release page of Thunderbird - https://www.thunderbird.net/en-US/thunderbird/releases/

I see 153.0 (the first release) is marked as ''esr'. But from 153.0.1, there are both esr and release. I would be great to understand the reason behind this approach.

Thanks in advance!

Hello,

I recently upgraded to a new PC from Windows 10 to Windows 11. For some reason I can not open links in any emails, even if right clicking them. I have gone through all steps here: http://kb.mozillazine.org/Standard_diagnostic_-_Thunderbird but nothing has changed. I have disabled Win Defender completely and still no change.

Any idea what I am missing? I am at a loss at this point.

Thanks for any advice or direction.

Since yesterday (27 Apr 2026) any and all mail that comes into Thunderbird gets marked as SPAM. I searched online and found people saying that I could reset the junk training filter, so I did this, but incoming mail was still marked as spam. The next suggestion was to delete the training.dat file. Did that, restarted Thunderbird and incoming messages are still marked as spam. The last suggestion was to turn off adaptive junk mail controls. Didn't want to do that because I assumed that it would let spam through. Nope. Turned it off, restarted Thunderbird and two emails from my work came in and got flagged.

I'm running version 140.10.0esr (64-bit) on Windows 11. I am using IMAP to connect to the mail server but it's not running any spam detection software (like Spamassassin). I know this because it's my server and even if it was, no updates have been preformed since the first of this month and this just started happening yesterday. Combine this with the bug that Thunderbird notifies me of incoming mail, even if it's spam (didn't post about this because there are plenty going back a couple of years), is starting to make me look for an alternative.

All was well until about six months ago. When I try to connect to my provider TB won't connect. BUT. At other times it will connect then every few minutes will try to connect again - then again .... I get this message "Connection to the server mail.comcast.net timed out". Then I get this message each time it fails "Login to server mail.comcast.net with username 170834000 failed". It keeps asking me to input my password even though everything is working appropriately. Then at other times it says it doesn't connect but it has connected and it still continues to ask me for a password.

I have uninstalled TB and reinstalled it thinking that would fix it - it didn't. I have changed my password - again to no avail. I let TB choose where to put things and configure each item appropriately. I don't try to get in the way of what works.

Comcast is apparently getting out of the email business and asking everyone to move over to their chosen substitute (Yahoo.mail) and I have not chosen to migrate at this point. Maybe that's the problem. This is the message I get each time I log into Comcast.net:

"A better email experience is now available for you

You're invited to upgrade your email account to Yahoo Mail, so you can enjoy a more user-friendly experience. Your email address, messages, folders, and contacts will not change.

With Yahoo Mail, you'll enjoy enhanced security, a built-in calendar that's easy to use, AI-powered inbox organization, and a top-rated mobile app for easy access on the go."

I am not aware of any changes in the settings from before when it was working well and now when it seems to be erratic.

I am not terribly computer savvy, but I'm usually able to trouble shoot and fix the issues that confront me. This time I'm out of my league! I need help.

Thank you for helping me.

Every five minutes Mozilla sends me a page asking for access to my Google account. I click "deny" and it goes away for a few minutes, but comes right back. And while it is on, I can neither send nor receive email. Is there some way to get it to go away and stay away? Thanks, Larry Wright

looking for an email i accidentally deleted from july 10. it was from walmart with a gift card from a friend. how can i access it? my deleted file only goes a couple weeks. thank you for any help. janis

Until recently, Folder Panes were visible at all times, but after the most recent update, they only appear when I am on a folder and are not visible when I am on a message. I have activated Views/Folders/Folder Pane Header, but that does not solve the problem.

Shortly after my most recent update, my Sent folder became corrupted. Rather than containing recently sent messages, it contained older messages from another folder, and when I send a new message now, it is not added to the Sent folder. When I tried to send a message, I received an error notification indicating that the message could not be archived because the folder did not have enough memory. I deleted everything from the Sent folder and then compressed it, but that did not solve the issue. I then closed Thunderbird, manually deleted the Sent folder from Mail/Local Folders; the Sent file was regenerated when I started the program again but with the same issue. I then backed up my profile, removed Thunderbird and reinstalled it, and then copied my profile over without the Sent folder. But when I opened the program, the issue still persisted.

The folder properties for the Sent folder indicates:

Name: Sent Location: mailbox://nobody@Local Folders/Out -- 148 November-Dec 2022

The location is obviously incorrect as it does not point to the Sent folder, but rather to another folder I use to store older message. I see no way to change the location, and the Repair Folder option does not solve the issue.

I would be very grateful for any suggestions.

Copiolet tried to hep me with many different ways. I am locked out of Thunderbird they said I could be frozen and tried to unfreeze it but that did not work Nothing is showing I have thunderbird in the downloads

Please excuse the length of this but it's necessary.

Began using Thunderbird (TB) in June, 2026 accessing email from wowway using POP3 (I know not imap, but old habits die hard). Changed password on wow in July and changed it in TB. Thereafter, and up until yesterday, TB was unable to logon to wow. However, the new PW allowed access to emails by browser logon to wow; old PW failed as it should. Frustrated with not being able to use TB with new PW: - deleted AppData/Roaming/Thunderbird folder (profiles and all) - recovered a backed up copy of TB folder from mid June when things were working and copied it to AppData/Roaming. Bingo, was able to get and send emails. Puzzled, looked at TB Saved Passwords and verified the old PW was being used. To verify this, I sent an email to myself, pressed F5 to get mail and it was in the inbox, and also on wow server.. BOTTOM LINE: There is no question that TB is using an old, changed wow PW. And if PW in TB is changed to new PW, access to wow fails. How can this be? Help please.
