Dear Support Team,

I'd like to understand the design of S/MIME signature / certificate validation in Thunderbird. Lets's assume the scenarion that a message with valid signature has been received but the certificate expires very soon (next couple of days).

In my opinion, the behaviour of Thunderbird might be a bit missleading. As enclosed, S/MIME information says that certificate is untrusted, which is not really accurate. The certificate was trusted when the message has been received but now expired.

I assume that Thunderbird validates certificate only against current date. But we have the message original date in the headers. Validation process could be configurable, like in popular pdf readers (which date to use for validation), or even better it could execute 2 validations in case current date validation has not been scuccessfull and S/MIME information could cover this scenario that the signature has been valid while message been created / recived but the certificate expired. It would definitely reflect real scenario in more accurate manner.

I'd appreciate if you could let me know if there is a configuration possibility which I'm not aware of. In case it is not available, can you please advise how I could submit a proposal of functionality enhancement? In case, there are rules comming from RFC standards restricting the validation of signature in a way that has been described, I'd also appreciate this feedback.

In spite of the above remarks, I think that you did a vary good job with S/MIME functionality in thunderbird. It is far more user friendly and well presented to a user than in other email clients.

Best regards, Marcin

After the last update to Thunderbird 139.0.2 on a windows 10 computer, the write button doesn't work. When I click it nothing happens. I receive messages and can even reply to messages I just can't write new messages. The error console shows an error: 1750426957343 addons.xpi WARN Checking C:\Program Files (x86)\Mozilla Thunderbird\distribution\extensions for addons UnknownCollectionError: Unknown Collection "thunderbird/moz-essential-domain-fallbacks"

I think I have turned add-ons off and still have the problem.

I'm trying to create a simple to do list. From the description, it seems that a "task" should work this way. However, when I try to create a task, I get the same options as for an event. And if I continue to fill that in, it shows up in the calendar as an event. What am I missing?

hello I left account A (Google) and I am mainly using account B (Google) now. However, when I search for the mail of account A, it only shows the result, but after clicking it, it shows that there is no mail. How can I recover it? This is because the most important mail is in account A. PLEASE HELP ME....

Hello!

We use some filters in thunderbird to manage messages redirection to other mail-boxes. When message body contains any image, it disappears after redirection via filter rule.

When you forward same message to the same person by hands - works great, nothing is missing.

Can you help with any suggests / advises for thunderbird client config to fix this?

We use Thunderbird 115.5.0 (64-bit).

Thank you.

I know this question has been asked before, but haven't been able to resolve the issue - I have in my Trash folder, the Spam and Draft folders there, no idea how they got there. I use multiple computers and have the same issue on all. I am running Thunderbird 128.11.1esr (64 bit) on my desktop, which is Linux Mint.

If there are any suggestions on how to move the folders back to their original location, would be good, unless I have to now live with it.

Thanks, V1King

On my new laptop (Acer Aspire) I set up my gmail account without a problem, but T-bird will not set up my business account (on my domain, hosted by midphase/stackmail). I used all the settings from my t-bird account on my old laptop, but nothing I try works. I get a yellow box with the message "Unable to log in at server. Probably wrong configuration, username or password". I also tried lettting Thunderbird find the settings; they didn't work either.

What next?

I was moving stored emails between folders. After many moves, when moving a group, the move failed with message "TOO BIG" APPEND  ??. Since then, I have been unable to move or copy even single emails. How can this be cleared?

I have set my account to "Don't delete any messages", because I frequently want to reread a deleted message in my Trash folder. However, when I go into my Trash folder to search for a deleted message, I am finding that messages older than a certain date have disappeared, although I've done nothing to permanently delete them. For example, today everything older than May 3 is gone. What can I do to prevent this?

thanks, CW

Hello,

In looking at new messages the inbox, there is a button to send it to the Archive, and another to send it to the trash. Both buttons work as expected. However, the trash button is sending the message to both locations. Is that just the way it is? Or is there a way to only send it to trash? I've spent some time searching the settings and haven't found anything other then disabling the archive altogether. I also didn't find anyone complaining about this, so I suspect I've missed something.

Thanks!

I am currently using old outlook and am thinking of switching to Thunderbird for better mobile calender integration with my gmail account. I do not like IMAP as I prefer my data locally and it impacts performance. One aspect of outlook that I use constantly is reminders on emails, meaning a get a reminder on the date and time I set to look at an email that I sent or received in the past.

Can this be replicated in some way with Thunderbird?

Hello, we are facing an issue like unable view the emails. Resulting in blankpages.

Same issue happened last month also.

Current version - 139.0.2 and the we are using UNC path.

Any advice would be helpful!

Edit : currently we have downgraded to the thunderbird version 138.0.2 and we are able to view the emails.

1. Thunderbirdportable 139.0.2: Nearly all emails work well. But the attached email doesn't present the inline pictures well. I tried outlook, foxmail, emclient and all worked very well. But TB cannot do it.

2. ThunderbirdPortableLegacy52_52.9.1 Other emails look good. Suddenly received the new email and it becomes plain text. Checked inbox online and tried emclient/outlook and all display the email in html. It also works on Thunderbirdportable 139.0.2. Really confused...

When I add any email that I receive from British Airways to my address book, Thunderbird does not hide the email address in the From display pane. I do not appear to have this problem with other accounts from which I receive regular emails. Could this be a problem at their end ?

can not send emails recently as about a month ago. Error message is :unable to authenicate to outgoing server. Please check the password and verifiy the authenticate method in account settings outgoing server . smtp not sure if i am doing this right? please help this old guy
