Thunderbird Community Forum

I have been setting up laptop for a local sports club. The underlying email account is a gmail account and I have used Manage Identities to set it up so that by default emails show as coming from the club's domain-related account, e.g. manager@sportsclub.uk. All seems OK; however, the email one receives from the account shows the correct signature, but still as coming from the gmail account Curiously though, if one hovers over the email address it shows the name of the 'manager identity' even though the display shows the name of the underlying gmail account. Everything is set up exactly as I have in my personal Thunderbird account which has several identities and all work as expected. The only difference is that my email account is a Plusnet one. So I assume that it must be a feature of gmail. Does anyone know if that is the case and what one can do about it?

Hi I have 2 gmail accounts set up in TB. Neither of which are my daily accounts.

I've noticed that both of them put a copy of any email I receive into archives, as well as my inbox. I've checked my account settings & they're identical to those of all my other email accounts.

Not only that, but one of the accounts puts every email I receive into inbox, archive AND archive for that email address, so basically, I'm getting 3 copies of all those emails.

What I want to happen is what happens for all my other emails. They arrive into inbox & I put them in local folders/delete as appropriate

All help gratefully received Thanks

Why does Thunderbird now label the Junk button as Spam, even through I have no Spam folder -- just a Junk folder? Also, in Settings Junk is now labeled Spam?? Screenshots attached.

I am using Thunderbird 115.5.2 (64-bit) on an older iMac on OS 10.12. I have four email address accounts, all gmail, and using POP. I have stored emails I wanted to keep in sub folders in Local Folders. This has all worked well for years.

Yesterday I lost lost all content from some of the subfolders in Local Folders, while some retained some content and a few seem intact. I also lost most emails that had arrived in the inboxes in the last week. The folder pane still shows the accounts, with their own set of folders. As usual, the inbox folders are highlighted with the number of new emails downloaded from the Gmail server to each address, but I can not see them in the message pane, or find them anywhere else. I sent a test message from one of my addresses to another – It didn't show as sent in Thunderbird, but did go through the gmail server and the message count of downloaded messages on the recipient address went up by one, but I couldn't see the email. Then I tried clicking on the folder "properties" then 'Repair Folder' but nothing happened, although the information on that window showed the number of messages and MB that I would expect to be in that folder, rather than what was there, which presumably means they may still be in there somewhere? I would be very grateful for help – I'm not tech savvy and feeling completely lost.

I can no longer send messages through the email client on one of my accounts using Thunderbird, which no longer recognizes my internet service provider's password (but it does receive messages). Everything works fine with my other accounts.

Thank you for your help.

I have 2 emails provided by my ISP (knology), I have received no emails since 7:30 on 12/5, the are on the webmail site. The other 2 emails are gmail accounts they are working fine. I am getting a message, "The certificate for imap.knology.net is not valid for that server. Someone could be impersonating the server, you should not continue."

 The fact that the gmails work and knology does not work is a clue but I don't know what it means.

I have contacted my ISP and after 45 minutes they gave up and said they will escalate and get back to me,

with in a couple days! it was on a Saturday.

I am having a problem with Thunderbird in that, seemingly at random, Thunderbird stops responding for a few minutes, then it deletes all but 2000 emails locally from my inbox, then, after a while, it re-downloads them all from the server. I have 96973 messages in my inbox on the server.

The email server in question is mail.yahoo.com

I am unable to recieve mail on thunderbird for the last several days. I am receiving the message "Alert from account xxxx@comcast.net: Temporarily blacklisted IP Address - try again later (comcast is my mail provider) where is this message coming from and how do I clear it. I use a VPN and have shut that off but has not fixed the issue. I have the same VPN running on my Iphone and am able to still recieve messages via the Iphone mail client... Any thoughts?

Hello,

I am requesting assistance with a persistent issue in Thunderbird involving a Google Workspace (Gmail) account for my domain, dantanas.com.

Incoming IMAP works correctly. However, outgoing SMTP authentication fails every time.

Symptoms

The Google OAuth login window never appears when Thunderbird attempts to authenticate SMTP.

Sending mail produces the error: “Unable to authenticate to Outgoing server (SMTP). Please check the password and verify the authentication method.”

IMAP works normally, but SMTP never prompts for OAuth authentication.

Thunderbird also does not allow me to have a Junk/Spam folder for this account — the option appears disabled or unavailable.

Current configuration Thunderbird is using

SMTP Server: smtp.gmail.com Port: 465 or 587 Security: SSL/TLS or STARTTLS Authentication: OAuth2 User: max@dantanas.com

IMAP Server: imap.gmail.com Port: 993 Security: SSL/TLS Authentication: OAuth2

What I have already done

Verified DNS MX and DKIM records on the domain (email receiving works).

Confirmed I can log in to the account in a browser with no issues.

Tried both port 465 and 587.

Removed and re-added SMTP servers in Thunderbird.

Forced Thunderbird to attempt OAuth2 authentication, but the OAuth window never appears.

Tested other clients, which authenticate correctly — suggesting the issue is specific to Thunderbird.

Expected behavior

Thunderbird should open a Google OAuth browser window to authenticate SMTP. This never occurs, which prevents SMTP from working entirely.

Request

Could you please advise:

Why Thunderbird does not open the Google OAuth authentication window for SMTP?

Whether there is a known issue affecting Google Workspace OAuth in Thunderbird?

How to reset or repair Thunderbird’s OAuth behavior?

Why Thunderbird does not allow the creation or use of a Junk/Spam folder for this account?

Any guidance would be appreciated. I’ve spent considerable time troubleshooting, and resolving the OAuth prompt issue is essential for SMTP functionality.

Thank you, Max Makowski max@dantanas.com

Recently I have noticed some changes in the way my Thunderbird downloads POP3 messages. Previously, it would be common to ask for new messages once a day and receive upwards of one hundred of them. But in the last month, this number has been limited to about 35 at a time. If I ask immediately again, I get about 35 more, and this pattern continues as long as there are messages in queue waiting to be downloaded. I am not sure if this is due to changes in gmail, where most of my received messages originate, or to changes in Thunderbird itself, or to some sort of third-party hack. Now that I have trained myself to keep on asking until there are no more messages coming down, this change does not cause me much difficulty, although initially it sometimes caused me to overlook messages because I failed to keep asking as long as I should have. Apart from that, it does not seem to be harmful as far as I can tell. I'd just like to know if other people have noticed anything similar, and if anyone knows what is causing it, and whether it has some hidden advantages over the way things used to work.

I've been wanting to access Thunderbird's encryption ability on both my laptop and desktop. However, in setting up Tbird on my laptop I notice the user Profile should stay on one computer. Can I use the same Profile on more than one computer using the same source and password? Can I open a new profile on a second computer, even though I would have to use the same email source, a local provider? If not, is there an online source of email data I can use on Tbird on my laptop. Thanks much, Bruce Bartrug

Running Thunderbird 140.5.0esr

This has been happening for a few weeks now somewhat randomly. The folders under Mail for one of my accounts keep moving around and are not in alphabetical order anymore. Most folders are OK, but a few either jump to the top of bottom of the list. I can manually drag them back, only for different folders to do it the next time.

The folders in questions are 2 levels down from Mail.

The folders in my "LOCAL FOLDER" file usually have been in alphabetical order. As I have added new folders to store emails, the new folders have not been put in alphabetical order in the "LOCAL FOLDER" folder. They have been added to the end of the original list after the "Z" items. How do I re-alphabetize the whole "LOCAL FOLDER?"

"Could not get folder db" is the message. I've tried all the suggestions that google provided - nada
