Error message when trying to send a message: Sending of the message has failed. Peer's Certificate issuer is not recognised. The configuration related to smtp.message.com must be corrected. When you click on OK, it brings up another lengthy description of licenses etc.. but no result. I'm trying to send a picture but I'm not sure how. In-any case, i'm sending this for my Wife's account: erika-b@netspace.net.au

We had a long-standing conversation with The Messenger Company, but the were unable to solve the  problem.

Hi Support, A customer uses Thunderbird as their main mail platform but suddenly cannot send or receive messages. error message as follows: Sending message failed. The message could not be sent because the connection to the SMTP server timed out. Try again. we get this message directly when we click send (1ms)

Now we checked our Mail Server, connection is up also TLS to port 587 works fine but the client can not establish a connection... it worked a few days ago tho. We also tried to reinstall Thunderbird, new profiles and also tried debugging but we could not find the mistake.

I have received an HTML-formatted message, which arrived with a red background colour. When I reply or forward that message, the message composition window appears with the same red background colour, and with black text. The resulting black text on a red background is hard to read.

How can I change the background colour of the reply or forwarded message which I am composing? How can I override the background colour set by the sender in the original message?

Note that I am asking about the background colour of a message which was set by the sender. I am not asking about how to set the default colour of messages I compose from scratch. Nor am I asking about how to set the background colour of Thunderbird windows or UI elements.

Thank you in advance.

Bonjour,

J'utilise 2 comptes de messagerie Gmail sur Thunderbird, et je dois toutes les semaines remettre les mots de passe google de ces comptes pour continuer à l'utiliser. Que dois-je faire pour supprimer ces demandes trop fréquentes.

Merci par avance, Hervé Serre

After Thunderbird just updated to Version 128.5.0esr today, now all my accounts are saying that the connection is refused. This is coming from three different email services that I have accounts on. I'm assuming it's not an issue with those servers as I can access them just fine with a different email client, and I didn't change any settings. Yesterday it worked, today it doesn't. Only thing that seems to have changed is Thunderbird got updated.

Some emails show a message body that's nothing but / separated groups of ASCII characters, as for example "FJ/OHS/U7R/R3A/NT4/R03/0QY/T1N/VRC/WJ3/J6E/YXK/I6K/WNA..." continued for several pages. These are generally (but I think not always) obvious spam - that one has subject "Try Semaglutide and join the millions of women losing weight fast." But not all obvious spam is shown that way.

Is this something that Thunderbird is doing, or is the gibberish the actual message? I've only bee using Thunderbird for a few months, and don't recall seeing anything like it with my previous email program (Opera). I'm using version 115.7.0 (64-bit) on OpenSUSE Linux.

I am receiving the following error message when downloading messages from AOL to Thunderbird. "The DELE command did not succeed. Error marking a message as deleted. Mail server pop.aol.com responded: Too many requests." Please could anyone help me download my messages? I have been away for a month, I have a lot of messages to download. Could that be causing the problem?

Hallo und guten Tag,

ich habe für Windows [PC] und Android [Pixel 8pro] jeweils die beiden aktuellsten Versionen von 'Thunderbird x64'und 'Thunderbird: Free Your Inbox' installiert und eingerichtet. Es sind zwei E-Mail-Konten mit jeweils einer Alias-Adresse eingerichtet, alles unter GMX.NET , IMAP+SMTP sind ebenfalls aktiviert [IMAP port993 und SMTP port465]. Leider bekomme ich es nicht so eingerichtet, daß Mails wenn sie am PC oder am Pixel empfangen und verschoben oder gelöscht oder als Spam markiert sind, daß dieses dann auch am jeweils anderen Endgerät so erscheint. Es werden immer wieder alle Mails neu als eingegangene Nachrichten gezeigt und ich muß dann am jeweils anderen Endgerät die gleichen Aktionen vornehmen.

Wo liegt der Fehler, was muß ich tun um das Problem zu beheben.

I am supposed to be on the esr release program, but today I was automatically updated to beta release 133.0. This is the second time this happened. Thunderbird shows a red screen, and recommends I install the last stable release, 128.5.0esr, which is what I want to do. But the last time, when I tried to go back to a stable release, it then wouldn't let me do that because it says the profile may no longer be compatible. I solved it painfully using timemachine backups of older profiles.

What is the simplest, safest way to downgrade, now that I am in this situation? And why is this happening?

Thanks for your help!

Cannot receive new emails after the recent SOFTWARE UPDATE. Have been using MOZILLA seamlessly up till this latest SOFTWARE UPDATE. The mailbox shows the new design but no new messages are coming.

ERROR MESSAGE: Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.

the geek squad copied all programs onto a new microsoft surface for my wife but did not ensure all software works as they don't want to access your passwords. when i go to set up thunderbird, i input the imap pw to the email server and first problem is that it doesn't remember the pw even though I ticked the box. second issue is that it is taking over an hour to open the folder inbox, then it downloaded 4 emails and went back to 'opening folder inbox'. clearly i am doing something wrong and would appreciate any help available from those wiser than i.
