Hi,

I'm a long-time user and big fan of T-Bird, but I've been having an issue lately that is driving me nuts.

When using T-Bird, the program frequently locks up for maybe 10-30 seconds, especially when deleting messages, transferring messages to folders, and when downloading new messages. This is super frustrating because it's hard to get much done when your critical software is frequently locking up the entire system.

This happens on all three of my PCs (two workstations and a laptop); two are Win 10, one is Win 11, and this problem is not happening with any other software. I've looked at the task manager when it happens and killed any processes that are taking more than a negligible amount of CPU, but that doesn't fix the problem.

It's hard to know exactly where T-Bird is getting hung up without the right profiling tools, but it seems to happen most frequently when accessing the network. At first I thought it might be a disk space issue, but it's still happening on all the machines even after optimizing the disks and deleting the recycle bin, temporary files, etc. to ensure there's plenty of free disk space.

The only thing I've tried that seems to help a little bit is turning off the quick filter.

I've tried asking support at my ISP (InMotion) if the delay might be caused by the mail server, but sadly they are a bunch of worthless idiots.

Any advice or feedback on how we might narrow down or fix this is much appreciated! :)

thanks in advance...

My house was hit by a lightning strike and it blew out my computer. It looks like both the drives in that computer are readable. So I am wondering how I can get all my email back into thunderbird. It was a pop account. All email was saved to computer. I'm using windows 10. I tried to just copy the old file at Users/Mike/AppData/Roaming but that didn't work. It didn't bring back all of the folders. Please let me know if there's anyway to rebuild all the folders and emails. Thanks in advance for your help. Mike

Hi friends,

I already searched for this topic and found that there should exist a file named "msgFilterRules.dat" - but there isn't such file nowhere on the whole drive.

Looks like the message filter rules are actually stored in a file with another name...

But what's that name?

Best regards rumbero

Thunderbird 115.10.1 If I receive an email in which the sender has added comments in red text, the text only shows as black despite View-Message body As-Original HTML being selected. I've tried selecting Plain Text and switching back, but no change. Is this a bug, or is there anything else I need to select? Thanks. Kevin

I use Mozilla for incoming mail, but cannot get it to send mail out. I get an error message to check my SMTP settings, which I have done repeatedly, and it doesn't fix the problem. I use those same settings to send my mail OUT with webmail (which is inconvenient to have to switch all the time), so I know the settings are correct. Can you help me understand why my outgoing mail won't work even when I verify that the settings are correct.

It was barely noticable, but SERVER NAME in Server Settings was the same for both accounts. These were Yahoo IMAP accounts. Each account had its own folder in Users / ....... / ImapMail, but both accounts were pointing to one folder. Corrected this in the SERVER NAME field in Server Settings (see image)

"SHOULD" solve the issue .......... particulary it is THE ONLY item I can find that was not normal.

I have a new windows 10 machine and have a new install of Thunderbird. Hosting email server has 2966 emails that I would like to recover. Started process of downloading them and got to 1895 when it failed with the error message "Unable to write email to mailbox" Check the settings. Tried removing the account and recreating it. Removed the 1895 emails that I have downloaded and got the same result. It seems to be broken some where between Thunderbird and the hosting mailserver as I can login via webmail and see and read the balance of 1071 emails. Techs at the hosting server company have no idea what could be causing the problem. Any help would be appreciated. Regards, Richard

When I Reply the cursor used to default to the text so I could just start typing my message.

Now it defaults to the address field. How can I go into the hidden settings to change it?

I like customizing everything, and when i used Outlook, when i rightclick on a email i could chose immediatly to send that mail forward to someone.

but in Thunderbird, i get :

mark as unread - answer - ( here would send forward be nice ) - archive - marks as not wanted - delete.

is it possible to change archive to , send forward :)

not a biggy, just if someone knows how to do it.. that would be nice :)

I get many messages with with unreadable text/background color combinations; near black text on a black background for instance. I searched for an hour on the web and played with themes and settings and couldn't find a way to make all received messages readable.

Does an imported TB profile overwrite the existing files in a new TB install?

I set up one existing account and have imported the profile for all my TB accounts. I am hesitant to import all of the profiles because of the one (oldest account) could be overwritten and TB did not leave any messages on the gmail IMAP server.

The other accounts do not exist on the new install (new machine)

I'm using MAC OS 14.6.1 on an M3 iMac

Emails are coming in (from Gmail) with the correct subject line, but the body says

"----_com.sonymobile.email_660493172259368--"

When I view source, there is a long block of Hex, several pages long and then "---_com.sonymobile.email_660493172259368--" at the end

They are fine via google gmail.

How do I fix this?

Hi E-mail message which i sent via Thunderbird contains in headers my internal and external IP in "Received from" record. Is it possible to hide it without use proxy or VPN? Recipient can see it.

I use the latest Thunderbird on the latest (Sonoma) MacOS. Whichever filelink service I try to add (in Settings > Composition > Attachments) that service appears with an exclamation mark in a yellow triangle (and I am unable to send links to large files). I thought that for Dropbox and for Box that might have been as a result of the limited file sizes allowed to be sent using my free accounts. However, for Thunderbird Send, WebDAV and *cloud after clicking "Add to Thunderbird" and then clicking "Add" to provide permissions I also get the same exclamation mark error indication. (refer image 1)

Perhaps the problem is related to selecting "Create link for Send service instance" (refer image 2) - I can't make the selection stick - when I close the tab and reopen it, that option is unselected.

What am I doing wrong or not doing? Help appreciated.

About 6 weeks ago, I was forced to change my Thunderbird (v115.14.0) setting for my POP Outlook (formerly Hotmail) account to use OAuth2. Per the instructions, I backed up my profile, deleted the account and reinstalled it with the previous profile files, using the server name Outlook.office365.com as directed. I also have backups of the profile under appdata going back several years.

I now find that the only emails from that account are those received within the last 6 weeks. Under appdata\Thunderbird\Profiles..., I see three directories: Outlook.office365.com, Outlook.office365-1.com, and Outlook.office365-2.com, all of different sizes. Also, under localhost, I see an even larger Inbox, Sent, etc. that appear to contain at least one of the missing emails, so I suspect that that is the location of the missing mail.

This is complicated by the fact that I have an email account through another company that also uses the server Outlook.office365.com.

I've tried changing the local directory under the server settings for the Hotmail account to each of the different Outlook.office365.com directories, but I still cannot see the old emails.

Can you help me to retrieve the old emails and place them in the same account? Or failing that, at least make them available in some other way?

Thanks.

Hi, I'd like to create a filter that uses a list of names or addresses to send emails to folders. So instead of "if sender contains" Political candidate #1 OR Political candidate #2 and on and on I'd like to be able to use a list of some format that contains the same information.

Is that possible?

How can I change the subject prefix (Re:, Fwd:, etc.) ? I would prefer "RE:" to "Re:" for my outgoing mails. "mailnews.localizedRe" handles recognition of incoming subject prefixes, but I found no pref for my outgoing mails. Thank you!

I would like to export all of the email addresses in a collection of email folders. Some text format would be nice, csv or, even better, tab delimited to pull into a database to summarize.

I'm running on an M1 Mac, Thunderbird version 128.1.0esr.

Is there some utility that can help? Or some way to Applescript it?

Thank you,

Gary
