Thunderbird Support Forum

My emails have large a lapse in time before the downloading catches up. For example right now my last email showing says 6:41 PM when it is actually 9:44 PM. This is costing me sales on items I have listed on the marketplace because I have no current notification via emails. Please help.

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.

emails load very slowly or the app stalls & doesn't respond. Often I have to tap twice to open an email. When deleting an email it can take a couple seconds especially when deleting multiple. I can hit the delete button several time & have to wait several seconds for it to finally catch up. This has been happening for a few months now & is getting worse. Sometimes the pictures in the message load one at a time. It was working right, then one day it started lagging & hasn't been right since.

Cox has tranferred my email accounts to Yahoo. I need to know how to connect back to Thunderbird. Had a discussion on your FB group with ANJE YELF.. She said to leave a message here and she would get back to me on how to do that. I have imap.

Moved to new country (UK) took TB data with me as instructed. Installed TB did put in email data. Uploaded TB data as per instructions. Opened TB and put in email password etc. All my current emails show up no problems and email account appears to work but none of the uploaded data appears even though it took 15 min to upload. It feels like it was uploaded to the 'wrong' place but I uploaded the data it to the TB folder as instructed. Any idea what I did wrong??

Process is below: 1. I can successfully navigate to add-ins and choose and add-in to download 2. I can successfully click Add to Thunderbird 3. The screen in the attachment below is shown 4. I cannot get past this screen. If i click Add nothing happens and Thunderbird eventually shuts down.

I am using Debian Linux in a virual env on chromebook currently on version 115.10.1 (64-bit) of thunderbird.

Need to be able to download TBSYNC and the appropriate add-ins to get caldav and Exchange active sync to work. PLEASE HELP :)

I am attempting to transition to Thunderbird. I have become quickly familiar with the HTML/CSS underlying the UI, and with the older userChrome.css structure for personal customization.

However, I can not figure out how to change the default background color of the message composition window -- which exists in a separate window from the main message viewer window -- from #2a2a2e to basic white.

Cracking open a copy of omni.ja in the app package, the only ID that I can find that seem to possibly be relevant is #messageArea, found in the following .css files:

chrome/classic/skin/classic/messenger/messageQuotes.css chrome/classic/skin/classic/messenger/shared/editorContent.css chrome/classic/skin/classic/messenger/shared/messengercompose.css

I have tried to override the default #2a2a2e color of the message composition area in my userChrome.css file, but to no success. (By contrast, it was easy to change the background color of the message viewing area with #messagePane)

I have tried the obvious step of changing the background color to white in the color settings option. Even after multiple app restarts, this setting does not affect the dark grey default background of the composition window.

Is there a name to this window div and a class or ID that i could access and customize through my userChrome.css file?

Thanks!

The program says I now have 11 emails which haven't been opened but there are no emails to open, just emails received previously. Apparently I am receiving but they are not visible to me. what happened and how to fix. I'm an amateur and don't understand computer commands.

Your response to: no calendar tab after installing lightning

"Not sure what you installed and why. The Lightning add-on is no more. The calendar has been integrated into Thunderbird since quite a while. There is no need to install an add-on. "

So if Lightning is no longer valid - please remove old references to it!! How do I get the old plain calendar tab on????

A while ago, I had to work offline so I had TB download my Gmail account messages. Now I no longer want these messages to be stored locally, because the Thunderbird folder is up to 10Gb, so I unchecked the box in Synchronization for 'Keep messages in all folders for this account on this computer'. I was hoping the TB would subsequently purge the offline folders, but apparently not. Is there a way to clean out the folders without affecting my online Gmail folders as in Inbox and Sent folders?

There is an email app provided by xiaomi on my phone.What in the email sent by this app contains a special format of `Date` fields.It looks like that: `Date: Thu, 2 May 2024 05:55:12 UTC` It doesn't look like others' `Date: Thu, 2 May 2024 06:05:15 +0000` or `Date: Thu, 2 May 2024 10:35:14 +0800 (CST)`

but it is still conforming to standards (or is it only parsable by the JavaScript Date method?)

After I modified windows time zone and restarted thunderbird. all emails changed time so this is not a time zone problem.

But this email shown two different times in the preview and detailed pages at this moment.

So can anyone tell me if this is a bug? Thank you.

I have been using three email accounts on Thunderbird, all for a long period of time, and all without any issue. Recently the one listed below has not been backing up, and I receive this message. I am not techie at all, so any response needs to be dummy down to a 5th grader level. Thanks!

"Non-overridable TLS error occurred. Handshake error probably the TLS version or certificate used by server mail.q.com is incompatible."

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.

tried to donate, it wouldn't let me click paypal, so used credit card, then just kept saying an error has occurred. You cant say I didn't try. You ask for donations then don't accept them.

I cannot receive certain emails sent by interactive brokers which is trying to verify my profile and information on file. They told me to contact my email provider.

Hi, I have used Thunderbird for many years and always liked it. I would like to know is there a way to tone down the brightness of the white message pane in email ?? It is very bright and glaring. Any white anywhere else I go is just fine. Thank You,, Banyarola
