Can anyone tell me how to blacklist incoming emails from selected addresses?

I can get T-bird to send unwanted emails to the "Junk" folder, but there are some that I would prefer not to even show up on my end, but rather delete them before they even get here (Facebook being the prime offender - hundreds of people I have never even heard of sending baby photos, etc.).

I contacted my ISP and was told that I needed to do this from the T-bird end. I cannot find anything in the Support section that addresses this problem. Thank you, Wolfgang

I'd really like the ability to whitelist a domain rather than add an email address to the address book. I work with booking websites that create unique email addresses for each booking and they keep ending up in spam. I'd like to be able to whitelist the domain they're coming from instead of trying to train the spam cannon that they are not an issue.

I get this message when I open Thunderbird. "Sending of password for user jhtimmons@embarqmail.com did not succeed. Mail server pop.centurylink.net responded: service temporarily unavailable."

The S/MIME e-signature does not function. (The problem occurred recently.) The system can not find the certificate (the certificate is valid, it is QCA23....73.crt). How the system searches for it? What should I set in Thunderbird to find it? The openPGP functions well.

Sorry in advance for the long reading.

For my personal needs I'm currently using the general purpose desktop platform UBUNTU 22.04.04 LTS and GNOME/WAYLAND. Thunderbird is my personal e-mail and productivity client application, now in it's stable version 115.8.1 (64 bits).

For many years I used to sign my personal emails using S/MIME and a high assurance (Qualified) X.509 digital certificate, protected by my personal ID card (i.e. a smartcard), which is provided by my government (Belgium). It used to work flawlessly under Xubuntu, my favorite OS flavor until about a year ago, with earlier versions of Thunderbird.

Since I migrated to UBUNTU's standard flavour (using WAYLAND), it doesn't work any longer.

I experienced the same behaviour with Firefox when Canonical started distributing only the SNAP version of the app for Ubuntu. This problem is well known and documented. I applied the recommended solution, which was - and still is - to install the Mozilla binary version along the snap version. I can since happily continue authenticating and connecting securely to any belgian e-government web site using the Mozilla firefox binary version with my certificates/Id card, while using the snap version for other purposes.

So I tried the same recipe with Thunderbird, ... to no avail. Both versions (Ubuntu-snap and Mozilla-binary version 115.8.1) display the same, consistent behaviour. I must precise here that I can load the BELPIC PKCS#11 subsytem and configure Thunderbird like I always did. After asking for my smartcard's PIN, TB can access the smartcard and lets me associate my certificate with my email account. Everything seems to work as usual until there, except that signing a message does not work. TB systematically displays the same error message "... the application does not find the certificate or the certificate has expired". Of course my certificate is not expired. It looks like the message composer (not Thunderbird itself) cannot access the smartcard. Disabling apparmor leads to the same result with both the snap and Mozilla versions of TB.

Still, TB - both versions - works as expected when using low-assurance digital certificates, e.g. issued by CAcert.org. I also use those for receiving encrypted personal messages when needed. But those are stored locally together with their private keys.

There is no interest in signing messages with a digital certificate without any legal value, especially on a system that is meant to be more secure. I migrated to the standard ubuntu desktop for the added security provided by snap, apparmor, Wayland, ...

Before I file in a bug record, would someone be in a position to provide any useful hint?

Many thanks in advance.

I don't want any passwords in order to access emails. There are no saved passwords or primary passwords in my settings, but I am still asked to enter one to access emails. How do I completely rid myself of ALL passwords?

Dear All

I am working as DPO in a small business where they use Thunderbird as Mail client.

I have 2 questions:

1. How do I get a Data Processing Agreement with Mozilla/Thunderbird?

2. How can I make Thunderbird GDPR compliant - Tips and Tricks? I am not a computer tech or specialist, so I need down to earth solutions and we don't have a tech support within the compagny.

Thank you in advance :-)

how do i setup 2FA for my thunderbird email account with the Microsoft authenticator app and how do i know my encryption setup is done correctly. I did this for my account but not sure if it was done correctly just want to confirm. Also recovery and backup codes can I have those too?

Windows 10 22H2, Thunderbird 115.5

Thunderbird periodically loses my saved passwords (11 accounts) necessitating the re-entry of said passwords. This has been happening for about six to eight months.

I have searched for solutions and have tried deleting the pkcs11.txt and secmod.db files but the problem reoccurs. There is no rhyme or reason as to how often this happens. If I new where the passwords were stored, I could copy the good password file back into the thunderbird directory.

Any suggestions would be greatly appreciated.

Thanks.

I would like to access the emails I received and sent under an account that no longer exists. All the data is still local, in my profile and I can see a partial preview of the messages when I run a search in TB, but double-clicking on one of those only returns a blank page. What's the best way to read those ghost messages ? Thank you for your help,

After recent update, TB seems to have created an extra account. My account has name <myemajl> and ends in ".com". New acct has same name but ens in .com_2. That's why I think TB created it. Which do I delete and how
