Thunderbird Support Forum

Like all of us, I get bombarded with spam emails. So I set up filters to separate the "definitely spam" from "possibly spam". I've been doing this for many years now. But recently, maybe for the past few months, I'm finding that these blacklist filters aren't working anymore. The filtering failure seems to be getting worse as time goes on. And, yes, I do a match on "any", but that still doesn't work. As I said above, my filtering rules used to work just fine, but possibly a new Thunderbird update several months ago broke filtering?

Also, is there a way for filtering on the message content URL? I find that sometimes that's the only way to distinguish spam.

Hello,

So - SMTP suddenly stopped working in our whole company. We are using Gmail accounts configured with Thunderbird for a few years already. It's all been working until an hour ago.

Tried deleting and adding accounts, changing authentification to google app passwords etc.\

SMTP servers do have different descriptions.

Just configured an account in outlook and it works out of the box, so I'm guessing it's got something to do with Thunderbird settings, but we didn't change anything, and especially that we have 8 PCs and it stopped working on every one of it.

The error I get when trying to send a message is:

"Sending message failed. The message failed to send because it failed to connect to the outgoing mail (SMTP) server "smtp.gmail.com". The server may be unreachable or not accepting SMTP connections. Please verify that your outgoing mail server settings are correct and then try again or contact your server administrator."

(translated from polish).

Best regards.

I tried a few times to copy the thunderbird folder from my windows machine to my mac machine but every time I start Thunderbird after that it just creates a new profile folder and ignores the existing one which was already copied. Any help and insight will be greatly appreciate it!

Hi,

I am running thunderbird-115.12.2-1 and Arch Linux and have the following Problem:

- I am using Unified Folders - Online search is disabled - If I change the view in any Unified Folder with more than 1 source folder to grouped by Thunderbird freezes and sometimes crashes - It does not matter what the sort by value is - Any time I switch from a not grouped by unified folder back to grouped by Thunderbird freezes and crashes sometimes again - The length of the freeze depends on the numbers of source folders for the unified folder. E.g. for my Inbox with 11 source folders between 5 and 10 minutes

I already tried - disable all addons - clear the disk cache - set mail.server.default.use_condstore to true - delete global-messages-db.sqlite

https://www.reddit.com/r/Thunderbird/comments/y795od/comment/jwk1kyp/

Right now the group by feature is not usable for me but makes it so much more clearer that I don't want to miss it.

Can you help me ?

When I read an email message, it changes the display from bold blue to bold black in the message list. If I then mark the message as read, the dark black changes to light black. Is there a way to do this once a message has been actually read, without having to mark it as read?

I have a Thunderbird on my laptop with a big folder in the Local Folder. It has a labeled "mail window" having 5,044 messages in a folder named under the internals of the Profile as "Family" and "Family.msf". Under "Family" are at the next level called "Archive-A" and "Archive-A.msf". (This may not be a kosher "archive".) I tried to use NanaZip to prepare as a zip by Exporting it the other laptop's Thunderbird in our house, but the process seemed to hang before that could do it. Maybe there had to be two levels, I dunno. Maybe getting from a .ZIP to a .SBD....

Even if that had resulted in a useful .ZIP, I'm not at all clear how I could I succeed in importing it into the main profile on the other TB computer. I am defeated at this point.

I wish I had a "Thunderbird for Dummies", or at least a manual + a lexicon with acronyms.

Could someone help me out?

Thanks!

I started Thunderbird yesterday and apparently did not recognize the profile. It required me to completely set up a whole new account for my emails. Consequently I lost a number of important emails. How can I get it back to my original account? And, for future reference, what is the best way to back up the emails in a manner that PDF or microsoft can recognize the format? Please advise.

I am considering moving to Thunderbird from MS Outlook. I want the rules I have already setup in Outlook to work in Thunderbird. Is this possible & if so how do I make it work.

Would you please help me permanently remove cache2 folder from Local Folders please. I'm using Thunderbird 115.12.2 (64bit) on esr channel with Windows 7 Ultimate Service Pack 1 OS.

I don't want Local Folders / Cache2 folder (or incidently Inbox, Drafts, Archives, Junk, Deleted and Outbox) but Thunderbird highlight - right click - delete button doesn't get rid of it. I can temporarily delete the Doomed and Entries sub-folders with right click - delete - delete folder but they move to Deleted folder where once again they can be deleted the same way but when restarting Thunderbird they are back under the cache2 folder again.

Even after exiting Thunderbird and directly deleting the cache2 folder(s) in system AppsData - Local and Roaming Thunderbird profiles the cache2 folder (with persistent sub-folders) returns to my Local Folders when restarted.

If ignored I eventually end up having a cache2-1 folder etc.

i have no memory of my password for email ,there are two emails , [edited] @eaglevalley,net and [edited] @gmail.com can you text me answer at [removed] 0r [removed]  ?

Recently I've had problems with the SMTP server refusing to send my e-mails, I am still being able to recieve them however. When choosing to enter a new window the window where you should put your passwords appear and dissapear at the same time. I've never experienced this kind of problems before. I even removed the account and the smtp account and re-added them back again to see if it would help but to no avail.

I am following the article from Mozilla called Microsoft OAuth Authentication and Thunderbird in 2024. But still it won't work.

Some of my emails are hidden in threads from previous conversations and not showing up as the last email received. If I am not expecting an email then I may never see it unless I happen to open up a previous that could be weeks earlier. I hate this and cannot conduct business when I can't see emails coming in . If someone is replying to a previous email , I may never see a new conversation. Only if someone sends an email that is not a reply am I guaranteed to see it. How do I fix this

Without notice, Thunderbird today required me to sign-in to my Google account and then produced a window in which it said it wanted to access to my mail, contacts and calendar; in order to compose, send, share, delete permanently, among actions on my personal content. I tried to "Deny" (see below) but the window just returned and returned and could not be deleted. (see "Uploaded images", below for the content of this window).

Is this a scam? Or the result of a hacker?
