Bonjour,

Comment contacter un administrateur Geckozone pour résoudre mon problème de connexion refusée car "nombre maxi de connexions dépassé" : je devais avoir la touche MAJ enclenchée ....

Merci par avance, GV

I am using ThunderBird, and when I mistakenly sent to the wrong recipient, I did not receive an email indicating a sending error (bounce). It is not in my spam folder or trash folder. What should I do to receive emails indicating a sending error?

Running version 128.10.1esr. This version and the two previous mark 50% of incoming emails as ***SPAM*** and put in Junk folder. Turned off SpamAssasin. Marked all as not junk. Added all addresses to address books. Nothing fixes this problem. There is no way to contact Mozilla directly for a solution so I am posting here. No, this is not email coming from a third party account like Gmail. No, it's not inheriting spam designations from another server. This is broken junk settings on the previous two versions of Thunderbird. Mozilla, please fix this.

Hello

I've been setting up Thunderbird on MacOS. I was adding few Gmail accounts. Every account was using 2FA so I had to enter new verification code each time. When I was adding 3rd or 4th account and was entering Google verification code into the form it suggested one of the codes I used before. Codes had same first two numbers so I guess I know why this form suggested one of the old codes but where does Thunderbird store these codes? I've deleted search history and cache in Thunderbird and attempted adding another gmail account but this time when I was asked for 2FA code I started with older verification codes and this form remembered all of them. Is there a way to remove them? Where does Thunderbird store these codes?

Thanks for any suggestions

The Help Article explains how to create a new email distribution list-- In address book, select "File", then "New" then "mailing list". in the drop down box for "New" there is no listing for "mailing list". I keep my version up to date but I would like to know why I don't see "mailing List" so I can click on it and create a new email distribution list. Your site tells me how to do this but it doesn't match what I see when I follow the instructions. Please advise.

If this is not possible consider it a feature request.

It would be great if we could set a list of email addresses (or have a checkbox in each address book contact) that would specify which emails to always send receipts to.

Communications have various degrees of importance. Some people you communicate with may be related to a specific project, for which you may or may not need return receipts.

On top of that, some people are busier than others. Someone may be receiving 10 times more emails per day than someone else. For them it's preferable to make sure the message you sent didn't slip through the cracks or have proof on your side that they received it. But for others, it's overkill, not very eco-friendly and clutters your inbox.

Manually specifying whether or not to send a return receipt on every message you send is risky, as you may not always think to do it, and then your important message sits for days or weeks before someone realizes it wasn't read.

我的邮件客户端为128.7.1，用的时IMAP协议。在客户端界面显示收件箱（包括收件箱下级文件夹）总共大小为78GB,但是在%appdata%中的thunderbird文件夹却有恐怖的795GB！！！我尝试压缩收件箱但显示只压缩了7.5GB。。有人知道这是什么问题吗？我应该怎样减小%appdata%中的thunderbird文件夹的大小？谢谢。

A few months ago the search feature stopped working. I used to be able to search for a message or messages by entering a search term in a search field, and/or using a filter like subject, sender, etc. But a few months ago that stopped working. Instead, there is no search field (except the general one searching for the term anywhere in the message) unless I click "quick filter", which then provides a more targeted search. But it calls up a random array of messages bearing no relationship to the search item. This is only on my MacbookAir. My iPhone also has Thunderbird but its search function seems accurate, only displaying what the search value is, except it doesn't get many when I know there are more in my inbox. My inbox is horribly overfull--I keep hoping to be able to find the ones I want to keep without deleting everything.

I checked the Thunderbird site and discovered much more complicated than the last time I looked. Right now all I want is the old one to work correctly. Thanks. Margaret Phillips

Since 5.18.2025 I get a "no message found" in my sent folders and other folders. "Find" will still find the messages and they can be opened, but I can't get the email folders to display. I know they are still there. Version 128.10.2esr. How can I get them to display in the folders?

Everything was fine in 115esr. I think I missed 136 and upgraded to 137, and am now on 138. I have five IMAP accounts. The following behavior happens with all of them and has been occurring since I upgraded (to 137 and 138).

I open Thunderbird and it checks for mail. Inboxes will show new messages. I click on any of the Inboxes with new mail. The spam emails automatically get marked as junk and moved out of inbox, and that happens only after I view that Inbox.

The previous behavior, and what I expect to happen, is that the spam emails would get marked as junk and moved out of Inbox before I view that Inbox. It's odd to have an Inbox show new emails, go to look at the new emails, then watch them get marked as junk and disappear from Inbox. It's like schrodinger's inbox, the act of observing the inbox determines the fate of the spam emails :p
