Forum Bashkësie Thunderbird

In one folder, one message received on 20th Feb keeps altering its date/time so that it appears AFTER replies I've sent in response. This has occurred following a problem with the same folder where several emails went missing, which I managed to restore with the Repair Folder function. Thought I might try looking in the file (not the MSF, the other one), but it's far too big for any text editor to open.

Good morning all.

I was wondering if someone could assist me in standardizing email signatures when sending a new email, and replying to an email. Let me elaborate a little bit...

When I compose a new email, my signature comes out like what you see in the `composing.jpg` attachment.

When I reply to an email, my signature comes out like what you see in the `replies.jpg` attachment.

I appreciate any assistance someone can provide, and guide me to the best way of standardizing these bad boys.

Have a great day!

I believe I'm on the newest release. I'm not low on disc space and I don't know how it would suddenly not have write privileges. I was archiving some of last years emails and it stopped shortly after that.

i cant send email from c_woolfoprdsales@comcast.net, woolfordsales@comcast.net or m_woolfordsales@comcast.net

I want to use TB as client for a twc.com account. I do not want a TB email account; I want to use it to access my existing twc.com account. I have downloaded TB but the only option I see is to open a TB email account, which is not my goal. How can I find the option to open the TB site and setup to use TB as client for a twc.com account?

I have multiple accounts in Thunderbird. I use Unified Folders for inbox. If I click "New Message" while in the Unified Folders view, the message will send from my default account, which is bill@billbauman.com. But, if I want to change my send from account to bill@ntur.ai, where I have a signature configured, the image in the signature fails to load. But, if I change my focus to select the inbox for bill@ntur.ai and click "New Message", the default send from account is now bill@ntur.ai, and the image in the signature loads just fine.

The image is publicly hosted and loads fine in any browser: https://images.int.dreamhosters.ai/account-482257/ceb3563cdab64978.jpg

I tried to make this as simple as possible for debugging, so I change the signature to just the image. Here is the code: <title>Email Signature</title>

I am running Thunderbird 147.0.2 (64-bit) on Windows 11.

I can make a screen recording demonstrating the behavior.

Does anyone have a solution for this?

Thanks all in advance!

Hello all:

Transferring Thunderbird from the system above to the system noted above. Follow the instructions from here on the Mozilla Support page (copied both "Thunderbird" directories into the Roaming and Local destination directories. When the destination machine installation opens, it is functional (i.e. it picks up all the existing e-mail accounts, downloads new mail, etc...). The problem starts when we get to the local folders.

All of these have a date and time appended to them in the destination installation. For example, if the original folder is "Prosperity Bank" the destination folder is labeled "Prosperity Bank (2025_09_21 23_06_33 UTC)" and will not let not populate (shows no messages inside).

As I am typing this, it seems I may have identified the problem (or at least part of it). It seems the destination system install is slowly working its way through the local folders randomly (not in alphabetically order), as it seems to be slowly populating them with the old mail stored therein on the original system. It is going very slowly. Very slowly.

Has anyone else experienced this? Is it normal? Is there any way to quickly eliminate the dates now appended to the local file names? (Visually this is very annoying and I do not want to try modifying the individual folder names yet until I'm sure its populated as much as it will populate.)

Thank you for any assistance.

Help, please! I have a twc.com account operating with Outlook 2007 on an old Dell Win7 laptop. It works great but too many websites refuse to recognize the Win7 machine, so I had to "upgrade". I just got a new Dell Win11 laptop and installed Spectrum email to access twc.com. So far, so good. But I need to access the hundreds of email files and folders from the old Outlook-based twc.com account. Can't export them to Spectrum.net as .pst because only Outlook recognizes that file extension. I do not want Office 365, so I tried installing Office 2024. But it's bundled with Office 365. I even installed an old version of Office 2010. When I tried to set up email with twc.com, I got a popup telling me that I had to get Office 365 to do this. Diabolical.

Enter Thunderbird. I downloaded and installed Tbird. I then attemped to use Tbird to be the client for twc.com. I've tried for several days with no success. First I had Tbird search for my twc.com account. Tbird said:

IMAP Incoming: IMAP, SSL/TLS mobile.charter.net Outgoing: SMTP, SSL/TLS mobile.charter.net Username: [edited]@twc.com

Results were quite different from what Spectrum had told me by phone (see below) but I tried this anyway. Got an error message: "Cannot find the server." etc.

So I tried manual setup using the information provided by Spectrum, as follows:

[edited]@twc.com incoming mail.twc,com outgoingmail.twc,com incoming port 995 outgoing port 587 security type TLS

Got the same error message: "Cannot find the server." etc. I then tried half a dozen different changes: change the security type, etc. Nothing worked.

I really need to succeed with this so that I can access all my email files and folders on one computer (the Win11 model). Any suggestions will be much appreciated.

I got an email to attend a meeting. Thunderbird popped up a screen for me to pick where to store the event, Outlook, Google or iCal. I tried all 3 and did not get it added to Thunderbird calendar. Can this be automated?

After providing my existing twc.com email address and other requested information, Thunderbird did a search and came up with "The following settings were found by probing the given server." I used those settings and attempted to create a Tbird-based account. I got this error message: "Thunderbird failed to find the settings for your email account." Which seems odd since Tbird provided those settings by searching the server. What can I do now? I hate to go back to MS Office but I need email and I've spent two days trying to figure this out, including a couple of hours on the phone with Spectrum (they were just as baffled as I am). I still can't use Tbird for email but pls email me at [edited from community support forum] @twc.com and I can access it on my old MS Office computer.

I successfully imported the self-signed CA certificate into thunderbird. Then I tried to import the p12 S/MIME client certificate and this error message popped up (cf. screenshot below).

However, I checked the client certificate and it seems fine:

What is going on and how to troubleshoot this issue as there is no logging about this matter into /var/log/syslog?

Environment: - Ubuntu 25.10 - thunderbird 2:1snap1-0ubuntu3

I've just received an email from breach-alerts@mozilla.com stating: You’ve been in a new data breach. Breach source: CarGurus. Yet there's no record of CarGurus in the Mozilla Monitor database. Is this an erroneous message? Or have I missed something obvious? Thanks

When I try to add my Spectrum email back in Thunderbird, it failing to connect when I enter my password. When I go to spectrum.net, I have no trouble logging in with my password. Whaat do I need to do to add my Spectrum email.

Without client certificate configuration, the user can retrieve its emails on the dovecot IMAPs server using a password.

When I try to authenticate the user with an S/MIME client certificate, the dovecot server reports that: ```dovecot: imap-login: Login aborted: Connection closed (client didn't send a cert) (client_ssl_cert_missing)```

Here is the configuration: 1. On the client side: I've imported into thunderbird: - the self-signed CA certificate - the user's S/MIME client certificate which is fine: ```

1. pk12util -l user@example.com.p12

``` I've setup the account to - use its certificate - use a TLS certificate as an authentication method. There is no S/MIME certificate option.

2. On the dovecot (2.4.1) server side: The server is configured to require client certificates for all IMAP connection: ``` protocol imap {

 ssl_server_ca_file = /etc/ssl/CA_CRL.pem
 ssl_server_request_client_cert = yes
 ssl_server_cert_username_field = commonName
 
 auth_ssl_require_client_cert=yes
 auth_ssl_username_from_cert = yes

} ```

Does that mean that I also have to import a TLS client certificate? If so, what format should it (.p12, .crt...) be?

I have been a Thunderbird user since way back in the Netscape days.

(1) I wrote about this a week or two ago.

My "SENT" messages STOP going into the "SENT" folder.

I can reset it by going to Tools / Account Settings / Copies & Folders and pushing the "Other" button & back to the "Sent" folder. Last time, the reset lasted a week or two. I don't know I have the problem until I try to find a sent message and it is not there.

(2) On my Wife's Thunderbird, when she has pushed the "Spam" button for a message in the "Inbox" - The message does go to the "Spam" folder.

How does she mark them as "Not Junk" ?

She marks ALL of the messages she wants back in the "Inbox" - BUT - The messages she has tried to make "Not Junk" continue going to the "Spam" folder the next time received.

My TB 147.0.2 Release channel is using excessive amounts of memory. Below is the memory usage data.

Previously I was on the ESR channel for many years. Also I originally used the Lightning calendar plug.

What I'm seeing is that when TB starts the memory usage is high. If I check at another time on the same day it is sometimes only around 250-350MB.

I've tried suggest options like reducing data in Local Folders (on a separate data drive) but to no avail. As I type now TB memory usage is now only 286.4MB. However rest assured in a while this will jump back to over 3GB and it has an is now 3,151.4MB.

I don't see this on another 2 PCs. One is setup with Locals Folders and the other is just the mail Inbox and sub folders. The only other difference is that the PC with this TB installation also has one Newsgroup server configured.

There surely has to be a bug somewhere causing these excessive memory usages.

End of Main Process (pid 13380)

Thunderbird now consistently fails on attempting to login to BT email. It worked fine one day and not the next. It now fails every time. It now just says "Host contacted - sending login information", then comes up with an error "Sending of password did not succeed". Nothing has been changed - no settings, nothing. I had not been anywhere near the setting but have now examined them and they are indeed exactly as they were and, having checked, are exactly as they are supposed to be. The saved username and password are as they should be and I am able to login to BT email on a browser using those credentials and send and receive email with no problems. It therefore appears that there is no issue at BT and the account has not been blocked due to too many login attempts. I have cleared cache, deleted and re-installed Thunderbird but it makes no difference. Are there any ideas as to how to fix this?
