Thunderbird Support Forum

I'm very confused. I've been using Thunderbird as my email server for a few years. Recently, I stopped receiving emails December 12, 2023. I sent in a problem according to the help page that I found. I believe Mozilla is now the server for Thunderbird? I don't even know if that is accurate (part of my confusion). I followed prompts and confirmed my email address, apparently I now have a user name. I still can't send or receive emails. Can you help. I need step-by-step instructions, please.

On March 14 I stopped being able to get my email. A message saying. "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox." What can I do? There is plenty of room on my computer and my server says all settings are correct

Clicking on any link in an email produces the following message.

"This file does not have an app associated with it for performing this action. Please install an app or, if one is already installed, create an association in the Default Apps Settings page."

I have no idea what this means.

I use Thunderbird to get my COX and Gmail emails. When Cox moves to Yahoo what needs to be changed in Thunderbird to get my emails? Below is what came to me from Cox: The countdown has begun and your Cox email will transition to Yahoo Mail in about a month. Rest assured, knowing you'll keep using your same Cox.net email address, messages, folders, contacts and calendar!

After the move, Yahoo Mail will become your email provider and Cox will no longer manage or support your email services. Yahoo Mail will make sure you stay connected by protecting your inbox with 2-Step Verification, Account Recovery Email and Phone Number, 1,000 GB of free storage and more.

Several of my message filters do not run automatically. The "Filter Log" shows only one of the 49 active filters running. That one filter does not run with predictable results.

I am receiving 10-20 inbound messages per day that may well contain malware or spam. These each have a "ReturnPath" of "<>" and an "AuthenticationResults" that contains the string "dkim=none".

I am attempting to somehow identify and discard inbound messages whose "ReturnPath" is "<>" and whose "AuthenticationResults" contains the string "dkim=none".

I've made several different attempts using several different filter instances. Each works as expected when run manually from the pane that appears in response to tools->"Message Filters". Each of these invocations appears in the "Filter Log" when run manually

I see no evidence that any run automatically, even though I have clicked the checkbox to turn them on. I've tried setting the "Getting New Mail" dropdown to both "Filter before Junk Classification" and "Filter after Junk Classification" with no apparent difference in behavior.

I've tried turning on the "Periodically, every 10 minutes" option with no visible impact.

Many or most of my rules apparently work fine, because each moves a specific message from my inbox to a designated folder. Those moves all happen -- and yet the "Filter Log" shows no record of any of them.

I am running Thunderbird 115.9.0 (32-bit) on a Windows 10 Pro system. I'm a senior developer with more than four decades of professional development experience. I'm very familiar with rule systems.

My email provider is Rackspace, and their technical support is not responsive. This volume of spam/malware is making my email client unusable.

I am eager to pay a monthly support fee -- either directly or through any of the many online payment options such as "buy me a coffee" and such -- in exchange for effective technical support. I have been unable to find any such providers for Thunderbird.

I understand that this is a community of volunteers and I appreciate your attention. I invite any suggestions for workarounds or fixes.

Recently all cox.net emails transferred to yahoo mail but kept the cox.net address. I prefer the Thunderbird format for emails, more options. How can I add them to Thunderbird? I already have them in Thunderbird with the cox.net address but no new emails are coming in on the ones that have already transferred to yahoo mail. (They didn't all go at the same time so I am still getting emails on the ones that didn't transfer yet.) Thanks.

Hello and thank you for your help, I am trying to find my old Mozilla Thunderbird, e-mail account my older computer does not work, anymore, I have not used my Thunderbird, e-mail account in over five years, because I am on a newer computer. And could not access my information on the older computer that does not work. I could really use all my information and EMAIL account for Thunderbird, because I have many years of information on all those emails, I can’t find my password, 0r email address for Thunderbird emails, because I have not used my Thunderbird account in over 5 years. My old computer does not work and Thunderbird Email is a great program. How could I get my old emails back? And working. If you could please give me more or less a time, and date, to wait for your response, so I can wait for someone to help me, and not lose that opportunity. It would be much appreciated, so I don’t miss contact with someone that can help me with this matter. I am in the East coast. And thank you for any concern in this matter please help.

I recently (on the 28th Nov '23) updated TB to the latest version. It was so awful though that I uninstalled it and reinstalled version 60.9.1. However, now my address book is empty. I did have an old csv file which I was able to import, but it's quite old and missing a lot of addresses added more recently. Where did the saved email addresses go? Are they likely to still be out there somewhere? Thanks, Ian

I want to single space my out going messages. I changed the paragraph setting from body text to paragraph format, this temporarily fixed it but it went back to double spacing

I have donated. but I keep being asked to donate almost everyday. when that happens my email settings change, its very frustrating. I am a senior, I donate what I can but I can't donate daily or weekly. I donated back in September and I will again in April. please stop this overly aggressive campaign. you were never like this before. Thankyou sincerely Susan H.

Question about Thunderbird 115.4.1 and Gmail. In the "All Mail" folder... I delete messages - but only to see them still there the next day. I tried empty trash as well as compact folder and expunge - but I clearly am doing something wrong. Can anyone tell me what I am doing wrong and help me?! I also tried both moving to trash folder in different directory as well as "delete immediately" in Account settings.

Hello, Experts:

First up, I'm a happy user of Thunderbird with some years of experience. I make use of filters, and up until about 2 weeks ago they all worked. Now two of my filters (not all) have stopped working automatically, and I have to go to Tools/Message Filters and run them manually.

I'm on TB 102.15.1.

I have deleted the non-working filters and re-created them. No change in behavior.

I would NOT like to de-install/re-install TB because it's a good deal of work, and TB is a critical system for me.

That said, I keep a laptop computer for travel, and the filters work on that platform. IS THERE A WAY to copy a file or folder over from the working laptop onto my desktop machine, where the filters have failed?

Thanks in advance, Bob

I have set up a number of Message Filters to automatically run when new email is recieved. None of the run automatically on new email. This is frustrating on it own however I can’t even run them manually on individual filters for the inbox. I have recently moved to Thunderbird for my primary mail client from Mac Mail and definitely like it better, but filters not working and working perfectly in Mac Mail makes it difficult to switch over completely.

When I attempt to send an email, I get this pop-up:

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: impout006.msg.chrl.nc.charter.net cmsmtp 15.181.97.27 blocked. Please see https://www.spectrum.net/support/internet/understanding-email-error-codes for more information. AUP#Out-1130.

My ISP is Spectrum, they said issue is with Thunderbird, incoming s/b 993, outgoing 587, which I confirmed. How can this be fixed?

Recent changes to #Thunderbird software are causing replies to my emails being attached to previous emails of the same thread and are not visible when they come to my inbox. Why and what solution? thanks Charlie

Build 115.4.2 (Windows x64 version) installed today and I found I was no longer able to select multiple folders in the left folder view to perform actions on. Neither CTL-click or SHIFT-click works. I tried rolling back to 115.4.1 and 115.3.3 but had the same problem. I finally reverted to pre-Supernova 102.15.1 and that fixed the problem. Any idea what the issue is with this operation in the newer builds?
