Thunderbird Community Forum

A few weeks ago I began getting spam in my inbox from about ten senders (Omaha steaks, C0stco, Marriot, Harbor Freight, Harbor Tools, Ace, Lowes, CVS, Blue Cross) and no matter what I do, I can’t make it stop. In fact, the numbers have grown higher every day - probably now over 100. Marking them as junk doesn’t work. I have triple-checked all my settings. And setting up specific filters with these names hasn't worked. I don’t have a spam add-on but I see here in Support complaints about SpamAssassin’s ineffectiveness.

Is anyone else getting junk from these specific senders? Has anyone discovered a way to banish them?

MANY THANKS

Thunderbird 143.0.1 eclipse.

Quite recently I noticed that, in the list of folders, I see 2 "Junk" folders.

On looking at the properties for 1 Junk folder the location is shown as "imap://*********%40gmail.com@imap.gmail.com/Junk",

but properties for the other shown as Junk locates as "imap://*********%40gmail.com@imap.gmail.com/Spam".

I've tried renaming that folder in Thunderbird to Spam but the change doesn't take effect.

What went wrong, and more importantly how can I rename it to see it as "Spam"?

tnx.

HI.... HELP...Got Hacked... All of a sudden, starting a week ago, I get 60 and more, unwanted E Mails from people I don't know, & have to go thru & delete them daily.. I have a list of my true correspondents & can re enter them, if there is some way of one time, emptying the Input box or what ever, to stop this from happening, every day...........Thanks. Ken

I am receiving the following error message on a Win 11 desktop running Thunderbird 128.6.0.esr (64 bit): "The folder '[Gmail]/Trash on my.fr33.email@gmail.com' could not be compacted because writing to the folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again." I do not have a folder [Gmail]/Trash on the gmail server. I also do not get this error on other Thunderbird clients running Win 10 or Win 11. I also do NOT get the error when I manually compact the my.fr33.email account, either at the account level or at the Gmail folder level. Once I acknowledge the error the system seems to run normally until is wants to automatically compact folders. Any suggestions will be appreciated. -- John Randle Knoxville, TN

Starting today (September 3), ALL of my received emails are being put into the Spam folder instead of the Inbox.

FYI, I have been running Thunderbird (TB) for years and have not recently set up any new filters.

I'm currently running Thunderbird 64-bit version 155.0 under Windows 11 Home version 25H2. I am also running Bitdefender Total Security, but I have turned off its Antispam function, both under my usual Standard User account and the Admin account.

I have tried:

1. Going into TB Settings|Privacy & Security|Spam and clicking on "Reset Training Data." 2. After closing TB, I deleted the training.dat file in my TB profile folder and restarted TB. 3. Right-clicked on my Inbox and Spam folders and clicked on "Repair Folder." 4. Exited TB, copied my profile folder to an external HD, uninstalled TB and reinstalled TB after downloading from the official download site. 5. Rebooted my PC.

None of these approaches has worked to solve my problem.

Thanks for any help you can give.

I just downloaded Thunderbird because Outlook is doing a bad job or preventing on these junk emails and I'm wasting too much time sifting through all the junk emails every hour. Now I have Thunderbird and I don't see an option to mark an email that is in my junk folder as not junk.

Hello, I have marked a number of emails as junk in the Suspected Spam folder. Why are they not immediately moved to my junk folder? Or do I have to move the marked emails there manually? Or is it better to delete them manually immediately after marking them?

Best Regards

I have a filter that moves emails based on the Sender... to a Local Folder (*) The system is set to [Filter After Junk Classification]

Every new email moved (by the Filter) to this Local Folder is marked as Junk. I manually set each email as not-Junk but the issue persists. (*) I have added a Filter action (as well as the Move): Set Junk Status to Not Junk (but this is not successful)

Any suggestions to fix, are welcomed.

I'm running the current 157.0.1 release on Windows 11, and specifically am having my emails from the AP be sent to spam even though I have a specific filter set to tag them. I feel as if the filter itself is set up properly because when I manually run it the messages will be moved from the spam folder to the inbox and tagged accordingly.

The one thing sticking out to me is these emails are being forwarded through my relay account. I've tried changing the filter to work based on the relay address, but again it only works when I manually run it. I've also tried setting the filter to run both before "and" after spam classification, but neither option works. Ideally the filter would work without me having to go to my spam and run it, and even then I'm wondering why the spam filter hasn't learned by now that those email belong in my inbox.

I'd appreciate any help or solutions; I'm not an email power user or networking wiz though so please try to keep it as dumbed down for me as possible!

Thunderbird does correctly mark emails I choose as spam spam. Problem is, TB fails to move these marked-as-spam emails to the selected spam folder. I've searched for cures here but nothing helps. Now what Mozilla??? See attached pics...

Hi I get out to 3 dozen spam emails a day in my inbox. I want to know if there is a way to send these directly to my junk email folder bu using the providers address. For instance, if I get quite a few from say @yahoo.com, is there a way to set up the filters so everything from @yahoo.com goes directly into the junk folder? Thanks, Marc

Yesterday Thunderbird worked just fine. This morning I tried to respond to several emails and got this error message: Sending of the message failed '"An error occurred while sending mail. The mail server responded: [VO=1] Message blocked due to spam content in the message. Please check the message and try again."

There was no spam in the person's email... just text.

Next I tried to send a freshly created email with just a YouTube video... then the last half of the error message said: An error occurred while sending: RBL restriction: Blacklisted by Internal Reputation Service - 195.181.168.179

What is going on??? The SMTP settings are correct: Port 587 STARTTLS Help!!

Hello: I send out newsletters to about 100 senior men golfers. I've been struggling with my messages going to spam or junk folders. My messages don't contain spam, but some mail servers are rejecting them. I've been working the problem (proper server authentication, DMARC, SPF, DKIM, etc.) but one of the suggestions I've read is to make sure there's an "list-unsubscribe" link in the email header. I've placed one in the body of the email at the bottom of the page (still fails), but how do I make a header in Thunderbird in which to place a link? Thanks for any help.

A couple of suggestions.

1) After opening an email marked as spam (by Thunderbird's spam filter), there is no option to confirm that this is, indeed spam. The email can be marked as "Not spam," but not confirmed to be spam. Unless I'm missing something, I have to go back to the inbox, mark it as spam manually, and then it is automatically sent to the spam box.

2) Assuming I understand the spam filtering correctly, once Thunderbird marks emails as spam, they remain in the inbox for at least 1 day (or longer if desired). I would like to have those emails sent IMMEDIATELY to the spam box, where I can still examine them to make sure they're spam before deleting them.

That way, the inbox will have only emails that either are not spam at all and those that haven't been marked as such.

As the system now works -- unless I'm misusing it somehow -- once the filter marks emails as spam, I still have to wade through them to sort out the good ones. In my view, that pretty much defeats the purpose of having the filter in the first place. I still have to "mark" them as spam again to get them sent to the spam box.

Perhaps I should note that this inbox gets dozens of spam emails every day and that I check it multiple times per day.

Right now when blocking a sender the deleted message go to "Trash".

How can I do a "hard/permanent delete"(Shift+Delete) when blocking a sender? Can this be done so that it bypasses the Trash and is permanently deleted?

Hi, until recently I used to get a reply-mail from my affiliate partner in my Thunderbird mail, but it's not working anymore.

I am trying to find a spam folder where I can check and possibly exclude that?

Please, help. Thanks.

Hello, All of a sudden when turning Thunderbird on, I have found that all messages in my Inbox have gone ( except a few for last day or two). Looking around Thunderbird I have found all Inbox emails have bee dumped into my Trash folder! Please help - how can I get emails back where they belong and get Thunderbird back into working order? Very grateful for any help' Thank you, kindest regards Brian Benger PS where will I get your reply if my email not working??

I don’t want any spam filters from Thunderbird. “Uncheck Enable adaptive junk mail controls for this account” never worked. https://blog.thunderbird.net/2024/09/thunderbird-and-spam/ The message "Thunderbird thinks this message is Junk mail" still appears. I’ve deleted Bogofilter.sfd, DSPAM.sfd, POPFile.sfd, SpamAssassin.sfd, SpamPal.sfd from Thunderbird.app/Contents/Resources/isp. What else do I need to delete from Thunderbird to get rid of the message "Thunderbird thinks this message is Junk mail"? I’m using Thunderbird 128.9 ESR on macOS 15.4.

Fix the problem; how can I see all that are in the trash folder? I need to be able to delete the oldest ones and access those sent there recently in error. The display says there are over 900, but I can only see nine and the dates are not the most recent nor the least recent nor consecutive.

There are certain emails that I receive that are *absolutely known* spam. I want these (but ONLY these) deleted as they come in.

I understand that one need to tick the "delete" box in Settings, but this seems to giver Thunderbird the right to delete anything that 𝒊𝒕 determines is spam. I don't want that. I want ONLY my own predetermined spam to be deleted.

And by deleted, I mean just that. Thunderbird just piles them up in the Trash folder, and this gets to be a big pile. Because Thunderbird makes mistakes, cannot just let it delete everything it determines to be spam, and so I have to go through this long list of junk in the Trash folder, which is annoying (because there's surely a better way that no one has implemented yet) and time-consuming.

I've made my own "delete" filter. It runs first (it's the first filter in the list), "before Junk Classification" and "Getting New Mail". Anything on this list should be deleted, because that's the ONLY action I have in this filter. If you're in here, you're gone.

Except your not. The filter is (for some reason) NOT run when new mail arrives. Instead, I have to open the filter, and choose "run on Trash folder". Then it works. But is THAT the design?!? Why is it not deleting arriving mail that meets the criteria?

There is also the problem now (as spammers have gotten more proficient) of the random character string preceding the @, followed by a domain name that you dare not mark as spam (for example, yahoo.com). These random characters are indeed random, and constantly changing, so you cannot filter on the address. But it seems to me some bright person might come up with something like "if 'known domain' is NOT preceded by 'known sender', delete". (This would require a user [me] to be very careful, or I could lose a new respondent who is not spamming me.)

But the point here is this: Over time, I have a great "delete" filter. Mail that this filter catches makes NO mistake. I want these messages (but ONLY these messages) to be gone when mail is retrieved. I don't want them in the Trash. And I don't want to have to take the time to run that filter on the Trash, because no one has created an extension that allows me to do this with a single click.

I would pay/donate, for this capability. But I can't bring myself to donate, or pay, when I have to go through a big Trash pile full of mail that, according to my filter, I should NEVER even see.

Other suggestions entertained of course.

But I'm spending too much of my life dealing with things that should be automated.
