I can receive, but not send, emails using Thunderbird on my PC. I believe this problem began when Thunderbird was updated on 1/13/26. I have no problems sending email on my tablet.

My service provide does not support TLS 1.2, so I tried changing security.tls.version.min to 1. This did not help.

The attached shows the error message and my SMTP settings (1st image) and my service provider's email server settings. I tried changing the SMTP port to 587, but this resulted in a time out error.

Any help is appreciated, Norm

I can no longer send emails. I can send them through mail web browser and was in touch with their technical support and the problem is not on their end. The message I get when trying to send an email is: "Sending of message failed. The message could not be sent because connecting to outgoing server(SMTP) Promail.ptd.net failed. The server may be unavailable or is refusing STMP connections. Please verify that your outgoing server (STMP) settings are correct and try again". I checked my outgoing server settings and they are correct. I started Thunderbird in Troubleshoot mode and the problem still occurs. I started my Windows 10 in Safe Mode and the problem still occurs.

I have just changed to a new pc. Thunderbird was working fine until Saturday when it stopped sending emails. I have discovered that the username on the outgoing server is missing but there is no method of adding it and I have spent all day trying to find a way, including twice reinstalling Thunderbird which has brought back the same issue each time. Any advice on the web seems to be for older versions.

My thunderbird email repeatedly keeps crashing after being open for about 5 minutes or so. Time after time for the past 4-5 days. I have sent reports each and every time but the problem persists .can you please help me I will have no choice but to cancel my account and donation. Thank youbold text

Thunderbird sends me spam reports, but I cannot open the mails considered to be spam, nor do I habe a spam file. I only have a junk file, but this does not contain the mails considered to be spam in the spam reports I get. Recently I received several mails I could not open because they ended up as spam. Why do I have a junk file, but not a spam file where I can decide if the mails are spam or not?

Purchased new laptop. Used export tool in Thunderbird to external HD. Traded in old laptop. Installed Thunderbird & attempted to import my email profile. Import tool requires zip file, but the only file on my external HD is a .default file. I'm getting new email but none of my old emails. Consulted Best Buy Geek & he determined the import tool didn't work properly because the export was missing required files. We further determined the export backup must not have worked properly.

When I have Thunderbird desktop running but I am focused in another application, I receive a popup notification when a new email is received. In the popup, there is an X to make the notification disappear, but it would be very handy if there was also a trash can icon where, if you clicked on it, the message would be deleted from your inbox without having to go back to the TB app. I didn't see any such options in TB settings, and I have searched the forum to no avail. Is this possible? Thank you.

I have created several address books in Thunderbird for my contacts. How can I add all the names in a particular address book to one of the fields such as Bcc without having to add them individually?

Thanks.

I am using version 147.0 (64-bit).

The New Line (Enter) key always double spaces, which is intended for paragraph text. But for tabular text, this makes unnecessary white space. What key combination generates only a SINGLE new line character rather than TWO of them?

Example: Donor: xxxxx Email: xxxxx Phone: xxxxx Billing Address: xxxxx Bank: xxxxx; Account ending in xxxx

This screen defaults to single spacing; why doesn't Thunderbird allow it?

I used to be able to send an email or forward an email by clicking on "forward" and my address book would show up at the left side of the screen and I could click on the names I wanted to send or forward the note and it would add them to the "send to" of my email so I could send it to multiple people. For some reason that has now stopped and I can only send to one person at a time which is very cumbersome and time consuming. Does anyone know how to solve this problem? I hope I'm describing it right.

I am using a E-mail server that uses LetsEncrypt certificates. I was using Thunderbird 128 ESR without problems. When the certificate was updated, I was requested to confirm - then sending E-mails was possible. Now I have updated to Thunderbird 140 ESR. The E-Mail servers LetsEncrypt certificate was now updated but in Thunderbird I do not get any information about this, nor get I requested to check the new certificate. The SMTP connection just fails. The IMAP access to the E-mail server works fine. (IMAP and SMTP work both fine with K9-Mail on my mobile device)

How can I get Thunderbird to ask me again to check the updated certificate?

html used to be easily accessed on the page of the individual emails. (see screenshot of it missing)

i have a need for it on an ongoing basis.

Can I make its accessibility just as simple/easy, without going to back to another release?

Linux Mint Cinnamon 22.3.

How do I restore selected emails or folders from a backup made with Export? I only want to bring in 30 or so (which were accidentally deleted). I'm using a Windows 11 PC.

I'm nervous about reloading the backup because it was some time ago (and I *really* don't want it to download new emails).
