Thunderbird Community Forum

I have forwarded (from my Thunderbird account) an email from our local hospital about an appointment to my mailfence address three times now, but all three were deemed undeliverable by the mailer-Daemon. I removed all links on the third attempt in case that was the problem, but no luck.

Error code: 554 Rejected : Spam ?

For further assistance, please send mail to postmaster.

How do I do that? Is my question. Is there a 'Postmaster' address to use?

Many thanks David Edwards

When we first started using a third party application to track our customers information & jobs; we received emails showing the customers name on the correspondent/from column. Now all of the emails show the third party applications name and I do not know which customers are trying to contact us.

Hello. Some email addresses are no longer being delivered and are not appearing in my spam folder.

This started about three weeks ago with just one address. Now, I know of at least two.

Emails from these addresses that I used to receive and delete have also disappeared from my spam folder.

Does anyone have a solution?

I have a calendar that is shared by 4 devices. If I snooze or dismiss a reminder on 1 device, it should not affect the reminder on the other devices. Please implement a local snooze option at the individual calendar level.

I have an address book setup with a number of what I'll call sub books for want of a better name. I used to be able to copy a contact from the address book to a sub book. I have either forgotten how to do that or something may have changed. I tried to drag & drop the address from the main book to the sub book but that doesn't work any longer. What am I missing here?

In my Thunderbird I have some folders with names printed italic starting with "INBOX". The folders are empty, so it's easy to delete them. After deleting I don't see the folders anymore. But after shutting down Thunderbird and starting Thunderbird again, the folders are back... How do I delete the folders to not see them anymore?

Best regards, Marianne

Thunderbird has been acting weird. For a week or so, it has sometimes been downloading only one message at a time when I hit "Get Messages." I have to keep clicking "Get Messages" over and over to download my email. Now, however, it won't retrieve any messages at all from that account. It goes through the motions, and says that there are no messages to retrieve, but there are. I have tried restarting, both Thunderbird and my computer, several times. I have tried compacting the inbox. I briefly got it working again after restarting, but it's back to not working and restarting does nothing. The online information tells me to delete my account and then add it again, but it also seems to indicate that if I do that I'll lose the email that is currently stored under that account. That's not an option! I am able to send messages, and Thunderbird retrieves messages from my other email account just fine.

I have tried all the recommended methods to alter the display of dates in my Thunderbird inbox but cannot alter the format as short. It is very inconvenient not to see the correct Day number.

TB connects to Yahoo Plus just fine. Folders display but no emails display?? I fixed this once a while back by deleting config files in TB and re-adding Yahoo. It has happened again?? Forgot which files I wiped (in Linux Mint). Anyway to avoid doing this continually and what's the fix?

Hi! I use Thunderbird at home, but at work I have to use Outlook. This M$ sh... uses Ctrl-Q to mark emails as read. After a long day at work, I go home, sit down at my computer, and automatically keep pressing Ctrl-Q instead of R. I'm sure I'm not alone in having this problem. Could you please allow users to choose which hotkey exits Thunderbird, or at least disable the hotkey?

Hi, I had/have an IMAP account at my ISP Host, with TB connecting to.

There has been a number of occasions where I have used the Servers IMAP copy of emails as a back up, and from memory am sure that when connecting a fresh client, all emails/folders etc updated and down loaded from the server > client, in fact nothing got deleted on either side, and both sides synced.

My host (Fasthosts - I will name and shame) deleted my whole IMAP account by mistake.

They hastily re-instated just the package but all the emails had been wiped from the server.

I did though have a full copy of all emails on my TB IMAP client.

When I reconnected my client to the server after the re-instatement, i expected my clients emails to upload to the server, but instead they 'vanished' - and I have nothing but empty folders.

Am I able to recover any of these emails from my client, ie are they sitting in a file/folder still ??

TB has restarted a number of times since, and I fear the folder may have been compacted, but I cannot be sure.

Thoughts appreciated.

I had to log in this morning, the first time as its automatic, and when i did all my folders and emails have gone. Where are they as there is important information in there which i need. The page layout is different too as i can't delete anything. HELP

My apologies, but I am not good at searching documentation and Q&A history without a glossary and ontology,

That is to say every (software) ecosystem has their own culture (tacit knowledge) and language (jargon)

I want to install mail user agents and web browsers on diverse systems, from e.g. RaspBerry Pi / RiscV etc. to desktops, laptops, on-prem hardware, and multi cloud distributed virtual platforms.

It would be nice to have a subset of the same server configurations and User Interface / Ergonomics descriptions (CSS) everywhere.

Regardless of machine architecture, kernel distribution, package manager, ad nauseum.

I used to be able to do this with trusted hash verified source or binary (reel-to-reel tape) or SHA256, e.g.), and trusted certificates. (e.g. pgp)

What we used to call tarballs for source, and RC configurations per user and per (virtual) machine.

I am SICK of Jenkins / Ansible / Dpkg / apt / yum / yaml / Nix .... as well as Snap, Flatpak, etc. etc. All in incompatible versions. I used to be able to create self-extracting shell archives that Just Worked on everything from mainframes to personal computers.

I CAN compile and run and modify ancient FORTRAN, COBOL, APL, LISP, and SnoBol without these headaches. I got paid very well to do this for Y2K in 1988-1999

Please take your time answering this screed.

In reference to the article [[Knowledge Base Article|http://mzl.la/1ApHiU3]], "Move Thunderbird data to a new computer", this misses the transfer of Local Folders.

The instructions only include moving the Thunderbird application data folder with profile information but does not include Local Folders, after completing these instructions the Local Folders will not be present on the new computer.

The path for Local Folders is under Account Settings > Local Folders, this folder needs to be copied to the similar path on the new computer as well.

I have copied emails from a Windows 10 to Windows 11 computer using these instructions and it appears to work.

Needed to edit an address. 2 problems: 1. somehow part of the address appears in the drop-down = home/work/mobile. How do I delete it? 2. edits are not saved (yes I have clicked save). Permissions all seem good.
