I can not receive or send emails with my thunderbird account. It keeps saying that the connection to pop.centurytel.net was reset. Can you help me get my email back please?

Latest version on W10 desktop machine.

1. Setting to open message in a new window does not work. Insists on making a new tab instead.

2. When Thunderbird window is active, kills attempts to use desktop icons for other programs.

3. Cannot minimize Thunderbird via taskbar. Have to hit minimize(-) from window.

Can any of these be remedied?

Since update my emails are all in dark mode, I used the button to turn off in email read, but cant turn it off in email reply, means I cant read what the person has said because the majority of people write emails in normal black on white. how do I get it back to normal? Thanks in advance.

I'm on Thunderbird 140.3.0esr on Fedora 41 Cinnamon

Yesterday and today when starting Thunderbird, message at bottom of page: connected to server(inbound.att.net) Never changes to "checking for new messages" or "downloading messages" so I am unable to get mail. Close and restart does not help. Seems to be be stuck.

On a different computer with the same accounts, functions normally.

Hello, I have a problem with Thunderbird that I don't understand and can't solve. Thunderbird can't connect to my IMAP account on the remote server perfectly even after a clean install. Incoming emails are downloaded, but only 82 out of 5600 outgoing emails. All login details are correct, I tried STARTTLS settings on the correct ports, but there is no change. I see in the Activity Manager that the connection between the server and the client is lost several times a minute. There is no network error, both I and the internet service provider have checked the connection. The client is running the Win11 operating system.

Hello,

I’m having an issue with Mozilla Thunderbird when using my WP.pl (IMAP) email account. Thunderbird keeps downloading messages endlessly — it repeatedly fetches headers and then tries to download all emails for offline use, but the process never finishes.

I would like to keep all my messages available offline, but it seems Thunderbird is constantly synchronizing and never stops downloading.

I haven’t tried any troubleshooting steps yet. Could you please advise how to properly set up Thunderbird so that it downloads all messages once and then keeps them stored offline without repeating the same process continuously?

I've been using Thunderbird for years (Windows 11 PC), and all has been working fine as recently as last night. Starting this morning, I continuously get the error message, "Login to server mail.comcast.net with user name xxx failed" (xxx not my actual account name). I've tried the "Retry" and "Enter New Password" options to no avail. I can go directly to the Comcast website, login and get my email that way, but I can't get Thunderbird to login.

To my knowledge, nothing changed between last night and today, but yet something seems to have happened. Any ideas appreciated!

Facendo segui alla seganlazione precedente relativa all' impossibilità di inviare posta con cui avete risposto con mail del 14/10 ore 9.00: l tuo IP è in una blocklist, probabilmente per spam o per altre attività anomale (non significa necessariamente che tu ne sia l'autore).

Prova a farti assegnare un IP diverso dal tuo internet provider (spesso basta spegnere il modem per qualche minuto e poi riaccenderlo).

Oppure contatta IOL/Libero/Virgilio e segnala la situazione.

In ogni caso non riguarda Thunderbird che si limita a mostrarti il messaggio di errore che riceve dal server.

Come mai da un altro pc riesco ad inviarla? Libero non c'entra e le configurazioni di thunderbird sui 2 pc sono le stesse. il fatto che il mio IP sia in una blocklist non mi è stato mai comunicato ne da voi ne tantomeno da Libero, quindi come si spiega il tutto se non per un'anomalia di Thunderbird. Attendo Ragguagli in merito. Cordiali saluti

When I'm composing an email, I can't move the cursor down past bolded text using the down arrow key. It just stays at the beginning of the bolded line. I can scroll up past it using the up key. This started a couple months ago, for some reason.

For months I have been working around a problem with Original HTYML message displays in my inbox. I have to revert to message body as Simple HTML for it to be readable. Please see the screenshot.

Hello.

I have added a new account to Thunderbird, and it is not syncing to show new messages. I am getting a pop-up from Tbird saying "The certificate for mail.newcreationloughborough.uk is not valid for that server ..." etc. I have gone through the procedure titled 'Troubleshooting email client warnings about invalid server certificates' to add Norton's certificate to my email app (as directed by the 'resolve' link in the 'Resolve email sync issues caused by certificate warnings' from the Norton EE Cyber Security add-on), and it tells me that the certificate is already installed.

What can I do next to get it to sync?

Hello, I reported this problem and you replied with a solution and that was to downgrade to version 142. My question is: Then what ? Will I be stuck with version 142 for years or is Thunderbird working on a solution to this problem because presently updating to any version such as 144 only continues to erase local folder contents. Thank you for your support Douglas Noades

I have recently installed Thunderbird on a Raspberry-Pi - additional to several Windows PCs

I'm using the same Mail-Adresses via Thunderbird - and on my MobilePhone - on serveral devices.

This all works fine...

But Thunderbird on the Pi has created two "SENT" Folders - one is named "Sent Items" - the other just "sent".

Now - only the one folder named "Sent items" connects with the IMAP - the one named "Sent" only remains local - Mails sent from the PI DO NOT show up in the "Sent" folders on the other devices - all mails sent from other devices show up in the Folder "Sent Items". But the Mails sent from the Pi actually reach recipients and receive answers.

The Location for the folders is listed under properties as:

imap://[username]@imaps.[provider]/Sent (on the PI) - folder "Sent" imap://[username]@imaps.[provider]/Sent%20Items (on the PI) - folder "Sent Items" and imap://[username]@imaps.[provider]/Sent Items (under Windows)

To solve the Problem, I tried to EDIT the line Location under properties, but this can't be edited (doesn't allow entries - or delete with cursor - nor pastes from Copy / Paste.)

So how can I synchronize the SENT folder(s) from the Pi with the Server...?

Thank you for any suggestions

changes in account settings do not save after closing thunderbird. when re opening the setting are back to previous settings.

In particular is the "attach the signature from a file check box and the file path in that field. changing the file....works as long as program is open. same with the check mark on or off....but as soon as you close the program and open it again the check mark is back on and the same old file name and path are there.....even if I delete the file completely from the computer...

Hello everyone I'm running TB 128 on Linux Mint 21 and TB 140.3 on Windows 11 24H2. My email provider is Strato.de with IMAP. The problem is that TB doesn't allow unsubscribes from folders on either installation. So, if you select a server folder, the folder is displayed and the emails are included. I can unsubscribe from the subscription, and the folders are not gone. All folders and Mails are on TB.

With TB, all folders are loaded and all emails synchronized during installation and the first contact with the server. I can deselect folders in the "Subscribe" menu, but they are immediately available again. I can see in the TB status display that the unsubscriptions are being sent. Strato reports that their server is OK. It also works with Outlook 2013 in Windows 11 and two other email programs in Linux. It works well with other clients (Evolution, Balsa) under Linux. I can uncheck the folders from Server (Dialog in TB) and they're gone.

Today I also tested: 1. Live version Mint 22 TB 128 - same problem 2. Mint 21 TB version 115 - same problem 3. New mailbox/address created on Strato's server - same problem Can anyone explain this? Thanks. Holger

PS: Google helps with translating

Thunderbird kept crashing, so I tried reinstalling. When I did, I was told to agree to an upgrade. I did. But now, it can't configure my account, and I've lost everything. Using a Windows 11 PC desktop. Everything was working fine until a couple of days ago when trying to send messages ended up crashing Thunderbird if I used the enter key.

Hi Folks,

I want to seek opinion on how to manage the virus detected in emails (or its attachments) through Kaspersky Anti Virus.

I have large no of emails in TB stored in mbox format. Around 30GB in Inbox and another 5GB in Sent, etc. I also use Kaspersky Internet Security which has anti-virus also active.

Now my anti virus detects some infected emails. How to clean the infected virus emails / attachments.

Question: 1) When using mbox file on TB, is Kaspersky capable to delete ONLY a single specific infected file from the entire mbox data without any corruption of mail data? 2) If not, how to setup the anti-virus to automatically clean, disinfect and delete/quanrantine individual mail. ?

3) Is MailDir a better way to save emails in profile and use anti-virus. There is a warning on Maildir saying its still not settled and may have bugs. Is that true even today ?

Thanks & Regards, Tejas
