Thunderbird Community Forum

Hello, I get oftem spam mails with a header like the following: from:Singles50 subject:Momenti speciali insieme per gli over 50 Reply-To:reply_to@miracel001.entrydns.org>

I tried to create a filter adding as personalized condition "Reply-to" that Thunderbird saves in the msgFilterRules.dat as: condition="OR (\"reply-to\",contains,@miracel001.entrydns.org)"

There is no way to get any filter working, do you have a suggestion on how to fix this issue ?

Thanks

Good afternoon!

We use Thunderbird for our business across several computers. However, on the main computer, we've suddenly received blank tabs at the top of the page, as if an open email thread is there. There are about ten or so of these blank open tabs, and you cannot exit them. The X button doesn't work on them, nor does Ctrl + W.

I've uninstalled and reinstalled the software, and we've tried a shutting everything down and restarting the computer, but nothing seems to get rid of the tabs.

Is this an issue others have experienced and, if so, what's the best remedy for it?

Thanks in advance!

Hi,

I would have posted this on this previous question by the same name https://support.mozilla.org/bm/questions/1266115 However it has been closed from further discussion despite being the top search google link for "thunderbird filter contains wildcard"

And what I wanted to say is that

This should long have been core functionality It is not even apparent when you make the filters, that wildcards (*) don't work So you make a ton of filters and they're silently broken !!!

I find the general filter creation process very cumbersome, almost almost every setting has to be changed every time, the main window, locks so you can't copy-paste from it mid-filter-creation and many many other quirks that make each filter creation an annoying 20 steps process, core among which, is the inability to create a destination folder on the fly while creating the filter !

But yeah, no wildcard support is kind of crazy

for example I want to put all emails from pizzahut in a folder

But they randomly change their From URL to @a.pizzahut.ca @b.pizzahut.ca @c.pizzahut.ca @d.pizzahut.ca @e.pizzahut.ca @f.pizzahut.ca

It's like they know the filters can't wildcard ! they is super annoying !!

I've tried setting up Thunderbird archiving according to the documentation to save archived messages locally, and in the same hierarchy they had when I archived them. That is, if I have:

INBOX

   Box1
   Box2

... etc. then archiving would create a parallel structure in Local Folders

However, this isn't working.

I select "Keep message archives in Other (Archives on Local Folders).

For "Archive Options" I select "A single folder", "Keep existing folder structure of archived messages" and "Recreate inbox folder".

However, when I archive something, Thunderbird just creates a folder "2026" (this year) and puts the message in there.

Why are my settings NOT working?

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.

I recently upgraded to TB 128.14 Oesr (64, Win 10). I’m a bit conservative about upgrading anything – as upgrades often waste a lot of time – if not risk justified.

Basically, If it’s workin’ well enough (cost vs benefit) …… well … “don’t fix it” – even though … “if it ain’t broke, doesn’t mean it isn’t sub-optimal”. Here, it seemed worth the risk.

My prior TB version – nope, I don’t remember which it was (is that in a log?) incorrectly identified bookoo normal e-messages as “junk” (junk filter deactivated) wasting a LOT of my time to move them back to the “indox”.

It also – CORRECTLY ID’ed – a big lot of data sucking spam as “junk” (junk filter still deactivated) for my PUBLIC e-address (expected spam magnet) – alerting me of the quantity of (expected) spam I was actually getting (my free Omaha steaks are on the way).

After upgrading (to TB 128.14) I don’t get any, well much of that spam any more (got a couple today) – hurrah (maybe)!! I don’t see it any more. It is gone completely (mostly, ostensibly) and the problem is – I do want to SEE it – all of it – in a “spam folder / directory” nd not in trash– wherever it is – to make sure it is NOT mis-ID’ed as spam – when actually an important message maybe telling me I’ve won the FIFA email prize!

So … “the game is a’foot! Holmes! How can I track down that missing spam – to see ALL of it – to verify it’s identity?

I suspect my hosting company – Hostinger – may be involved – as I did verify, previously, with my previous TB version – that they COULD see into my TB account structure. Can’t find it now, but previous did see MY TB account named “Aviation”. They, Hostinger, said THEY aren’t “moving” anything anywhere – not into “Junk”, anyway. Are they lying (as popular as that has become recently)?

I’m not smart enough to understand DKIM (though I could get that way) just want to see ALL email sent to ALL my e-addresses that didn’t get there – wherever it is (not immediately, I would hope)!

Merci,

Dru

I have been with Primus communications for many years, they are no longer supporting email address and I have to sign up with a new company they have nominated. I want to know if how my emails are managed in my Thunderbird screen will all be transferred and that I will continue as normal with Mozilla Thunderbird

Using Thunderbird version 140.8.0esr on Windows 10 . Been trying to reorganize local folders. Thunderbird is NOT correctly alphabetizing local folders. I've beaten myself to death googling for answers, and nearly every entry claims you can right click on the account name and select "Reset Folder Order" and it will take care of it.

there IS no such option! Anywhere!

Other answers claim you can drag the folders manually into the correct order. Not happening!

There must be a real answer to this issue. Where do I find it? And please don't advise upgrading to Windows 11 - this CPU/motherboard won't support 11.

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.

昨日の夜を最後に、メールの受信・送信ができなくなりました。 アドレス関係なく、会社のパソコンすべてです。 また、当初は一台だけかと思い、その1台のサンダーバードソフト内で、よく使うアカウントを削除し再登録しようとしましたが、ログインできませんの繰り返しです。'bold text'

Hi

I use the Messaging Company for emails and Mozilla Thunderbird as the email client. For the last week or more, I receive a message "Unable to connect to imap.themessagingco.com.au Please try again later. If the problem persists, you may have exceeded the maximum number of connections.

Under the instruction of The Messaging Company, I have modified the advanced settings for the server. The Maximum number of server connections to the cache is now set to 1 rather than 5. I have also changed I also changed the Thunderbird's IMAP Timeout from 100 to 120

These two changes have reduced the number of error messages but I do still get them.

Can you help resolve this?

Thanks

Judy

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.

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 used to use CCLeaner browser, but I have changed my default browser to Chrome. However, when I click on a link in an email in Thunderbird, it still sends me to CCleaner browser. I can "copy link address" and paste it into Chrome, but it would be more convenient for me to be able to click on the link and go to Chrome directly. Where in Thunderbird can I change this?

Whenever I try to search my various emails for some text, at least 40% of the time it shows me the attached message. I'm on Version 149.0.1 but it's been happening ever since I installed Thunderbird (maybe 4 or 5 months ago?) My first move is to check that I haven't mis-spelled the word I'm looking for (which I usually haven't) and I definitely know that the word is valid for one or more emails. So why does this message keep appearing?

Previously I'd been running an old 32-bit version of Thunderbird (which I don't have installed any more) but I don't remember ever seeing this with the older version.
