Thunderbird Support Forum

For some reason, my Thunderbird recently "updated" to version 115.10.2, and the "About Thunderbird" dialog says that it is on the "esr update channel." I can find no information about the esr channel. However, when I start Thunderbird, it displays the "Welcome to Thunderbird DAILY" screen. Am I correct that this is an error? If I were really on the daily channel, I think that the version number should be higher.

In general, I like Thunderbird, have used it for years. But if there's one thing that will make me abandon it it's that incoming links are not hyperlinks, they're just text. From what I've read, that's deliberate. If not, how do I make incoming links be links? I'm really ready to move on.

We have been using Thunderbird with a Cox email account. Cox has just transferred all its customers to Yahoo. I want to use Thunderbird with Yahoo. How do I set that up?

There are many answers to the question of how to disable message threading. All are from earlier versions than mine, which is 115.7.0 -- as witnessed: Sorry! 0 results found for ‘disable threading in version 115.7.0’ for ‘Thunderbird'

Thunderbird seems to have so many minor changes and alterations in the recent past, that basic usability is affected. Not a good thing.

Once before, a few years ago, Thunderbird got so out of control that I had to go to a different mail client. Are we back to that?

Need to set up Thunderbird to receive emails from yahoo. Cox is transitioning emails to yahoo presently have two addresses : cliven@cox.net and daciaandclive@cox.net

I can receive emails but cannot send. The error message I get when sending emails. This began as of the most recent Thunderbird update:

Sending of the message failed. An error occurred while sending mail. The mail server responded: <mjndoug22@me.com>... Relaying denied. IP name possibly forged [70.109.132.97]. Please check the message recipient "mjndoug22@me.com" and try again.

I tried to attach/imbed a screenshot of my SMTP server settings but your Browse button below won't allow the paste.

I had to replace my hard drive and now have Win 11. I still have my Thunderbird account, but I cannot access the 3000+ emails in my folders. My Thunderbird started from scratch, no history, no files. How do I access and download my saved emails and folders from before the hard drive replacement? The Geek Squad couldn't help. Keep it simple, I'm not a techie.

I am assisting my friend Lindsay in aged care to enable him to continue to use Thunderbird for email. Currently TB will receive mail but unable to send.

This is complicated in that Lindsay is paying iPrimus.com.au a monthly fee to enable him to use an old email address xx@bluep.com. I can log in to the iPrimus web portal to send and receive xx@bluep.com emails, https://webmail.iprimus.com.au/?_task=mail&_mbox=INBOX.

I downloaded Thunderbird version 115.6.0 (64-bit) on my pc this morning and the Auto Set Up configured mail.bluep.com as the incoming (POP) and outgoing (SMTO) servers. Mail is coming in but not sending.

I changed the outgoing server to smtp.iprimus.com.au, default port 587 however messages still cannot be sent and Thunderbird shows that smtp settings must be reconfigured.

I spoke this morning to iPrimus Tech Support who advised the default smtp port should be 25, not 587. However I have found that resetting the smtp port to 25 does not enable emails to send.

Note that I have previously set the smtp port to 587 which enabled sending on non ISP connections. This ability would be required as Lindsay is using whatever Wi-Fi service is available in the facility.

iPrimus Tech Support have suggested I should contact Thunderbird (Mozilla) about this problem.

Can you advise Thunderbird server settings for this situation.

Thanks for you assistance. Regards, Peter M

Im using Thunderbird Beta release. Starting last week, my PC would become extremely slow, to the point it would nearly come to a complete halt. After digging around, I realized it was due to excessively large Thunderbird NSTMP files that were being created. I would delete them and the speed would improve. But then a while later, the NSTMP files reappear and gobble up all my Harddisk again. Part of the issue is the sheer large size of the file, which will consume all available space on my HD, which at present is 600GB. But it also eats up all my RAM so my system slows down til the NSTMP file is fully built.

I use this as imap with Gmail installed on a PC with a 1TB SSD

Today after my pc started slowing again, I started poking around and noticed my main Inbox is massive, 29GB, which there is no chance its that large. All Mail is only 1GB to give perspective

This has been going on about a week.

I tried repairing my inboxes and other folders, but that does not seem to have helped.

I set up a new computer, windows 11, and downloaded the latest version of Thunderbird. On the old computer the spam filter works normal, on the new computer Thunderbird puts a lot of normal mail in the spam folder. Is there a way to set the spam filter to not flag so many emails. I use gmail for my mail server. My iphone also uses the same gmail account and does not filter these messages

Suddenly, I can't send email from my Thunderbird (115.6.1 (64 Bit)) Windows app. Spectrum is my email provider. I can receive email just fine. However, when I respond to an email and when I send a newly created email or replying to a receive email, I get the following error message - " Sending of the message failed. An error occurred while sending mail. The mail server responded: <[edited] @tx.rr.com> sender rejected. The email address you are sending as must match the email address you used to auth. Please check your SMTP settings. AUP#Out-1500. Please verify that your email address is correct in your account settings and try again."

I've been using Spectrum and Thunderbird for many-many years. This problem is going to cost me big-time if not resolved soon. I love THUNDERBIRD!

Please help!

My email address is - [edited] @tx.rr.com [removed phone# from public]

How do I change the order of my email account folders in Thunderbird 115.6? I have multiple accounts and just added another, and I want to move it from the bottom of the sidebar to a higher location. I used to be able to click and move around accounts in the "account settings" mode. Now, that doesn't work. Is there a solution? The instructions provided in the video created by Thunderbird in 2022 doesn't work! Please help!

I have Thunderbird version 115.5.1 installed on my Windows 11 laptop. I have logged into my gmail account and subscribed to google calendar. I have turned the off default reminders for events and don't have any extensions installed, but when I create a new event and select "No Reminder," Thunderbird automatically sets a 30-minute reminder. I can modify the reminder by editing the event after saving, but I can't directly create a new event with no reminder.

I've just now noticed the Threading automatic default grouping/marking of messages, and it is appalling. Thunderbird/Mozilla either needs to eliminate this (with appropriate warning notices, perhaps) or at least give us the ability to NOT link various messages. It's not only vastly annoying, it can cause severe real-world problems if anyone not in the CC or BCC fields is receiving these messages that were not intended for them.

I suppose for now, the only way to NOT link things that were never meant to be would be to change the Subject when discussing important topics.

Either that, or get a whole new mail service, which I'd prefer not to have to do.
