Thunderbird Community Forum

I keep my mail (both sent and received) in local mail folders. My server is gmail, and sent mail is put in gmail's sent folder by default. Every few months, I copy those messages to a local folder, and after I back them up, I delete the server copy.

What to my dismay, I discovered today that only the message headers, and not the messages were present in the local folder, though they had been when downloaded. Looking at the file sizes, I found the sent file to be 0 Kb, and sent.msf 255 Kb, when sent should have been around 60 Kb long.

I have been able to restore the messages from backup (whew!), but I have no idea how then sent file was wiped out. I know I did not do it.

Has anyone else had this happen? Is there a preventive measure I should take?

I have everything I need from my old machine except my e-mail filters. If I copy the whole profile I will lose all of the sent messages and saved messages I have generated since I got Thunderbird up and running on my new machine.

Email will not send. Message-- "Sending of the message failed. An error occurred while sending mail. The mail server responded: Email rejected. Please verify that your email address is correct in your account settings and try again." I am not sending to another person but testing with my personal email. Thank you.

Mail filters for custom headers like List-Unsubscribe or Authentication-Results copying messages from IMAP accounts to Local Folders do not work on the Yahoo! IMAP account. For example:

filter1.jpg: name="_Inbox2: List-Unsubscribe <https" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Inbox/_Inbox2" action="Stop execution" condition="OR (\"list-unsubscribe\",contains,<https)" (should copy messages from IMAP folders to _Inbox 2 on Local Folders)

filter2.jpg: name="Spam: Authentication-Results dkim=unknown | Received-SPF fail | X-Antivirus-Status Infected" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Junk" action="Stop execution" condition="OR (\"authentication-results\",contains,dkim=unknown) OR (\"authentication-results\",contains,dkim=perm_fail) OR (\"authentication-results\",contains,dkim=none) OR (\"received-spf\",begins with,fail) OR (\"received-spf\",begins with,softfail) OR (\"received-spf\",begins with,none) OR (\"x-antivirus-status\",is,Infected)" (should copy messages from IMAP folders to _Inbox 2 on Local Folders)

But filter3.jpg works well: name="Inbox" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Inbox" condition="OR (subject,doesn't contain,t[k\6iq69pd+}'cr)" (copies all remaining messages from IMAP folders to Inbox on Local Folders)

(the snippets above are fragments of the msgFilterRules.dat file)

Filters1 and 2 work well on other IMAP accouns, like for example wp.pl. So this is about Yahoo or something is corrupted. My question is, what wrong is here ? And by the way - how to create filter copying all messages from IMAP to Local Folders ? Is better way then filter3 looking for random string in the subject or somewhere else ? Thank you.

I'm using TB 150.0.2 on a Mac with the latest update of MacOS.

I just deleted all of my archived emails, thinking it was stuff that I had sent to trash. I.e. I deleted all archives, then emptied trash. Only after I did that did I realize that I had deleted things I want to save.

I'm pretty sure there's no way to undo emptying the trash, but I use Time Machine to back up. If I open time machine and go to the most recent back-up, I should be able to get everything back, right?

What folder (or folders) should I restore from a Time Machine back-up?

For some reason since reinstalling my Thunderbird every time I try to sen e-mail I get the error "Sending of the message failed. An error occurred while sending mail. The mail server responded: <SantoshS1@vbeyond.com>: Recipient address rejected: Access denied. Please check the message recipient "SantoshS1@vbeyond.com" and try again.

They are perfectly valid addresses, as they are generated using Reply. This did not happen before I was forced to reinstall from scratch. I suspect it may be some sort of issue with my account configuration in Thunderbird, as I had to recreate that.

Okay, so how to be simple. I kept getting a pop-up from Comcast about a latest promotion and it wouldn't go away. I spoke to Comcast about their ridiculous pop-up promotion, it was coming through my Thunderbird email client. That may be taken care of. But in the meantime I tried to delete my main Thunderbird account, I must have done so and now I can't get it back! I've tried everything! I was using an IMAP account, and for my incoming I had imap.comcast.net. For my outgoing I had stmp.comcast.net and the ports were 993 and 587 I believe. Please don't quote me on this. So when I try to create a new email account using the same information I keep getting an "Authorization Error" each and every time!

So....since and while writing this email, the Comcast pop-up continues to pop up, and I still cannot reset my email account. Talk about a frustration level at this point! I would like to keep my Thunderbird email account minus the stupid Comcast pop-up. I just don't know what to do. Please help from anyone who can!

Thanks,

Michael....

I'm on a new Windows 11 desktop with two monitors. Everything's been working just fine up until around 26th April (two weeks ago) when the native Thunderbird new mail notifications started appearing in my second monitor, rather than my main display. I had made no changes at all myself.

I've been through all the fixes suggested via Google (toggling the displays; checking Windows notification settings), but none of those fixes have made any difference. I switched to using Windows system notifications for a while, but I really don't like them.

Might this be something in a Thunderbird update itself? It just doesn't seem to be detecting the primary monitor at all. All my other app notifications continue to show on the primary display.

Has anyone else encountered this or have any other solutions I could try?

Thanks, Averill

Thunderbird Only Provides My E-Mails of the past two or three Weeks on my mobile phone and on my Laptop. Die Older Mails kann online be accesssed on the Vodafone Webpage. How can I synchronise My Account?

Starting yesterday for no apparent reason TB has been unable to connect to my email accounts. (IMAP or POP). These include Roadrunner, Gmail and Outlook.

Any Ideas? James

Unable to open NEW Email on one click. i need to wait for 4-5 mins to open that email. even i am not able to open on one click which contains Barcode. which email contain barcode its also not reflecting in email and even i need to wait for 4-5 mins to open that email.

Kindly help me for this matter i need to change any settings.

I have placed a question, did not get any response and can't even find my questiomn. Cost me masses of time to scrol throughj the forum

How can I find my questiomns

Not sure what has happened to my PC but lost my Thunderbird app.

Reinstalled but cannot get my emails working again. I only get emails up to 13th May 2024; I guess when TSO Hosting finished?

I am now on 123 Hosting.

I have a note that SERVER for both i.e. Incoming and outgoing is:-

sxb1plzcpnl503269.prod.sxb1.secureserver.net (smtp as prefix)

Where and in what format do I enter theses server details.

I think I also need to get into cPanel but the URL I have will not work:-

https://sxb1plzcpnl503269.prod.sxb1.secureserver.net3 (:2083)

Sorry but I am confused; don't get old!

I have created an account instance in account settings, and the "Test connection to server" says it is OK, but when I go to the mail tab the get messages button and New Message are grayed out an NO accounts are listed in the "folders" area. Not does it ever ask for my password to the SMTP server I have selected. I have an existing account with my own email service (Hover), and MUST connect to that. This is critical, as I need my e-mail to accomplish necessary activities.

As a die-hard fan of Mozilla products for many years, I genuinely want to say thank you to the Thunderbird team for keeping such an amazing open-source project alive and improving it continuously. Thunderbird is still one of the most trusted and powerful email clients ever made, and many of us truly love using it every single day.

But from the bottom of my heart, there is one feature I strongly feel Thunderbird now urgently needs.

Please give Thunderbird a complete Mozilla Account–based sync system, just like Firefox.

Today, whenever we shift to a new computer, we still have to manually:

• reinstall extensions
• reconfigure settings
• restore filters
• restore signatures
• adjust preferences again
• rebuild our personalized setup

For long-time Thunderbird users, this takes a lot of time and effort.

Firefox already gives us such a beautiful and worry-free experience:

• Install Firefox
• Login with Mozilla Account
• Everything comes back automatically

And honestly… that experience feels magical.

As Thunderbird users, we dream of the same simplicity:

• Install Thunderbird
• Login with Mozilla Account
• Extensions auto-install
• Settings sync automatically
• Filters & signatures restore instantly
• Everything feels exactly like our old computer

No stress. No manual setup. No fear of migration.

This is not just a “feature request.” For many loyal Mozilla users, this would be one of the biggest quality-of-life improvements Thunderbird could ever receive.

The Thunderbird team has already discussed this idea publicly for years, which gives users hope that someday it may finally happen.

Please make Thunderbird truly cloud-connected and worry-free for the next generation of users.

Many of us are not just users of Mozilla products — we are emotionally connected to them. ❤

Trying to remove Thunderbird. Windows add or remove programs isn't working. I'm trying Program Install and Uninstall Troubleshooter, which needs Thunderbird's product code.

I can't find it on the site. Can someone give me a hand?

I downloaded Thunderbird into a new computer and there are a lot less emails than on the old computer. I cannot find a setting to download the rest of the emails. Can you please help. Please send me an email telling me if I can download the rest of them.

My inbox is now put in alphabetic order thanks to one of the newest updates. I want it at the TOP. Can you fix this? In Thunderbird I now have to manually drag it to the top each morning.

When I open email in outlook my Inbox still appears at the top where it should be.

I hope this can be fixed sooner than later.

If this isn't the right place to post this please provide an email to post to. The website is not user friendly enough to be of any help to me.
