Thunderbird: форум сообщества

Hello. I am trying to add a new provider, which means adding a new account. When I click "Add new account" it takes me to a page that asks me to enter my existing account. Does this mean the currently running account or the new account?

I need a filter on a message to FULLY FINISH before a next message starts to be filtered. The "help" (quotes because it's an abyssal crap) says that simply ending the filter with Stop Filter Execution does it - but that's simply NOT TRUE: calling a console program in the filter, I can see five DOS boxes opening at the same time with five messages matching, i.e. the filters on the next message DID NOT wait! So... what can I do??

All of the above is because I'm getting "Too many simultaneous connections on the server". I'd like to limit the concurrency, but it only seems to be possible in IMAP, while this connection is a POP. Why only IMAP??!

On T-Bird start up I'm given a list of (originally) four Profiles. Currently I only use Profile Three, but on start=up today it is not there. Doing the usual searches does not list it, only 'default', 'new user' and 'profile two'. Is there any way to recover it?

I've been using Thunderbird for years at this point and it was fine, but then some time after the latest update I stopped getting new emails. I tried a bunch of random "solutions" I found on the internet and I don't remember exactly which one, but eventually I got the web portal to pop up, and it showed that I'm logged out of all my accounts (they all gmail, btw). Using this windows I was able to log back into one of them, but then it didn't popped up again to let me to log into others. For a day or so I was getting email from that one account I logged back into, but then again, suddenly, no new emails. I decided to just start over on a new profile and that's where things went from bad to worse. Now I can't even get past the initial logging process. It gives me "unable to log in at sever" over and over, no matter what I try. I tried a bunch of different config suggestions, I tried the old school way of getting a device password, I've checked if localhost was running something - it wasn't. I tried uninstalling and reinstalling, installing an older esr version (I'm on Win10, thought maybe that has something to do with it) - same thing. Unable to log in at server. I can switch back to my old profile that doesn't get any emails anymore, I've backed it up, but what's the point. Kinda feeling screwed on all fronts here.

Also, whoever is replying to people on reddit with "thunderbird employee" badge, ghosted me after one message. Great support /sarcasm.

Version: latest (whatever auto updated updated to) and 140.8.1esr OS: win10. Mail provider: gmail.

Hello,

Everything working just fine last night. Wake up and Thunderbird will not retrieve emails.

Remembered this old message I got so I went through and deleted my second email address, didn't help.

https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo

Checked all settings compared to Yahoo, still won't download messages. I can even send a message with my current settings no problem, and it does login, just won't retrieve emails. Gives me a connection timeout.

Anyone have any ideas?

I set up a filter to move messages to the junk folder. If it's not from a .com, .net, or .org domain, move it. Here's how I set it up... If the "from" incoming message doesn't contain "any of the following" ".com" ".org" or ".net" move it to "junk". It moved .com and .org messages to junk anyway. What did I do wrong? There are too many TLDs to create a filter for all of them.

what and who is meadow and why am i getting comcast mail sooner than thundershower it is just to slowit used to come up so much faster id get the new mail quicker now its so slow aand i do not want to uninstall and reinstall and lose my contacts and my extensions please if you know why so slow please let me know i know i sent one like this earlier but i though maybe gibving it time would be better but no it is not

I am trying to add one of my Google email accounts to Thunderbird. It brings up the "Sign in with Google" window, which is normal. But instead of "Sign in to continue to Google...", it says "Sign in to continue to Mozilla Thunderbird Email". Which then generates an error: "Error 400. The server cannot process the request because it is malformed. It should not be retried. That’s all we know." I've not ever experienced this issue before; adding a Google account has always been super easy and straightforward.

Hi

When Thunderbird is started maximized it overlap taskbar if is set to hide and taskbar won't show until Thunderbird is minimized and maximized. Another way is to press the Win key two times. Then the hided taskbar can be shown/use. The same thing happens to Firefox. Only when is first started. Then if Firefox is minimized and maximized, press Win key two times, press F11 two times then the hided taskbar show/hide normal.

It is a setting that can be changed to start Thunderbird and Firefox in full screen and do not overlap hided taskbar?

I just had a support session and the tech was unable to solve the problem. We tried installing a new version of Thunderbird and importing the messages over from the default install and it just freezes up. He tried replacing account settings with the account settings from a previous version and that didn't work either. He suggested contacting Mozilla to see if there was a way to import messages from the frozen default to my new profile.

I received a spam message this morning that had a "Disposition-Notification-To" (aka Read Receipt) line that had MY email address on it. I honestly don't know why a spammer would do this - but that's not the issue. I have Read Receipts disabled, but Thunderbird generated an email (to me) and sent it to my mail host. This seems like a bug. Even if the Read Receipt has my email address on it (making it mostly harmless), Thunderbird shouldn't have generated the message. Or am I missing something? Thanks.

hello, i cannot seem to find a solution online, hopefully someone can help.

i often receive emails with images attached, and most of the time people don't resize their images. you can imagine over time this all adds up in the email storage folder total size.

i dont always need to keep a 6mb image version, it can be reduced after i am done.

i would like a method to resize the received emails image attachment, to at least still have a smaller copy for refence, but not end up with a huge thunderbird email account profile (in the email received not externally saved)

preferably a one click solution, or even a routine i can run on the file system, etc. or some way to edit the received email and its attachment in program.

thanks

Can get(POP3), but can not send emails to a newly created personal outlook.com account.

the following error occurs when trying to send mail: Unable to authenticate to Outgoing server (SMTP) . Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)

all my setting are correct per thunderbird and microsoft:

  (smtp-mail.outlook.com, port 587,  STARTTLS, OAUTH2, xxxxx@outlook.com)

thunderbird error log file contains the following: . . . mailnews.smtp: S: 535 5.7.139 Authentication unsuccessful, SmtpClientAuthentication is disabled for the Mailbox. Visit https://aka.ms/smtp_auth_disabled for more information. [CH5P220CA0005.NAMP220.PROD.OUTLOOK.COM 2026-02-28T23:29:21.878Z 08DE7703D4D1982A]

Based on my understanding its seems thunderbird is using SMTP AUTH instead of OAUTH2 as required for newer personal outlook.com accounts. Is my assessment correct? If so, is there a fix?

I've been using Thunderbird on Windows 10 since last year sometime. Currently I'm on version 151.0.1.

I've 4 x mailboxes here and since yesterday, 3 of them show me an unusual message when checking for emails. I tried attaching a screenshot but although the screenshot uploaded, I couldn't find a way to insert it here. But the message says Unable to write the email to the mailbox and asks me to check if I've write privileges (which I have) and to cheek the available disk space.(currently 101GB free).

The message is happening 2 or 3 times each day and lasts for about half an hour, then everything works fine again. Has anyone else seen this??

I have no idea why Thunderbird stopped working for me and I can't seem to solve the problem - one day. I got a notification to re set my credentials - nothing since

after setting up a new install on another pc (ver148) and moving the profile folder over,

the only issue i have so far is the little yellow star in the folder for new mail having arrived in is not showing up. it will show the number of new msgs on the taskbar icon only.

can this be fixed?> can seem to see it in settings.

image attached of how it looks on the old pc

thanks

Why is Thunderbird consatntly coming up with "Authentification failure while trying to connect to server outlook.office365.com"? It never used to and would download my hotmail emails perfectly until about a month ago. This is very frustrating, I have removed my hotmail account from thunderbird and re installed it, works for ocassionally the back to same old message authentification failure. What is going on with thunderbird?153.02

Mail filters for custom headers like List-Unsubscribe, Authentication-Results or Received-SPF copying messages from IMAP accounts to Local Folders do not work on the Yahoo! IMAP account. For example:

filter1.jpg: name="_Inbox2: List-Unsubscribe <https" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Inbox/_Inbox2" action="Stop execution" condition="OR (\"list-unsubscribe\",contains,<https)" (should copy messages from IMAP folders to _Inbox 2 on Local Folders)

filter2.jpg: name="Spam: Authentication-Results dkim=unknown | Received-SPF fail | X-Antivirus-Status Infected" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Junk" action="Stop execution" condition="OR (\"authentication-results\",contains,dkim=unknown) OR (\"authentication-results\",contains,dkim=perm_fail) OR (\"authentication-results\",contains,dkim=none) OR (\"received-spf\",begins with,fail) OR (\"received-spf\",begins with,softfail) OR (\"received-spf\",begins with,none) OR (\"x-antivirus-status\",is,Infected)" (should copy messages from IMAP folders to _Inbox 2 on Local Folders)

But filter3.jpg for Subject works well: name="Inbox" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Inbox" condition="OR (subject,doesn't contain,t[k\6iq69pd+}'cr)" (copies all remaining messages from IMAP folders to Inbox on Local Folders)

(the snippets above are fragments of the msgFilterRules.dat file)

Filters1 and 2 work well on other IMAP accouns, like for example wp.pl. So this is about Yahoo or something is corrupted. My question is, what wrong is here ? And by the way - how to create filter copying all messages from IMAP to Local Folders ? Is better way then filter3 looking for random string in the subject or somewhere else ? Thank you.
