I have seen many questions a bit like mine but they all refer to downloading emails. Mine is different: "The folder 'Trash on my@email.com' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again." It now happens on two different email addresses (one is POP one is IMAP). Trash seems otherwise to work and can be deleted. But still this alarm. MAS OS 15.1.1 (24B91) - latest Thunderbird 128.5.2esr (64-bit)

Have a folder on my yahoo webmail account with >100K emails accumulated over time. The emails are of no lasting value

I just received a notification (via a banner on yahoo webmail when I log in) that my storage is full (never seen this before, but not surprised that Yahoo would be looking for "additional storage" revenue - not interested.)

I'm attempting to delete the emails in this (large) folder (which are of no lasting value), so far with no success.

The initial problem is that yahoo's functions to expunge (permanently remove) the emails (after moving them to their trash folder) does not work (either 0% progress overnight, or progressing 0-100% progress, in either case all of the emails remain in their trash folder and I continue to be notified (by the banner at sign-in) that email storage is full (and I do not wish to purchase any additional storage from yahoo.) As this is a non-premium yahoo account, no support exists.

It appears that yahoo webmail does not expose their trash folder via imap (it appears empty on imap view). Thunderbird "empty trash" on the hosted Trash folder shows no contents and completes immediately with "emptied trash".

I've now tried moving emails from yahoo's trash folder to another (new) folder on yahoo webmail, then using thunderbird imap to move those emails from yahoo to a local folder. My expectation was that "move" means gone from server, present on client. That appears not to be the case.

While this step does create a local copy, a copy appears to be left in yahoo's trash folder which still cannot be removed, so the core problem (of their impact on yahoo webmail storage) is unresolved.

I understand that "expunge" exists in IMAP but I don't see how this can be used with Thunderbird.

As I'm somewhat going in circles trying to solve this problem, I'm reaching out here for advice.

Thanks

Hello I have asked this before but i did not get an answer i could use i did get an answer but it did not work. So i am asking again. I can run Thunderbird for like a month and then all of a sudden all inbox mail goes to trash folder abut not with the name of the sender with my name as the sender I have reinstalled several times i have changed my security gone from 64 it to 32 bit removed some add ons or extensions. Now it is run from Comcast email and that is correct as far as i know.

I hate to stop using Thunderbird but if this keeps happening i may need to. the only extensions i have in Thunderbird enabled are emojis, config button, restart, and ublblock. Not sure how to get to filters and change any thing. Thanks Please i need help thanks upset Thunderbird user

I use an AOL email account and Thunderbird on my Mac. In Thunderbird, the junk mail folder - which AOL call "Bulk Mail" for some reason - has moved to the Trash folder and I can't get it out. It's a Thunderbird problem - if I go onto my account at AOL.com, everything is normal. How do I get it out? I've tried cutting and pasting it, creating a new folder...nothing seems to work. I don't want to empty the trash in case I no longer have a junk folder at all

The last few days most of my emails have been tagged as ***SPAM*** and automatically moved to my Junk folder. I have to be sure to check that folder. I've tried "training the app by moving valid email to the inbox but the problem persists.

I saw people posting for over a year about the "Geeksquad" FAKE emails. This still hasn't been corrected, and I am getting them also from the criminal enterprise. They all pretend to be from Best Buy/Geeksquad. They all have Click buttons with the SCAMMER website rxvtom<>.com within the email. Block this Junk, please, before any more people get hurt

I will provide FULL HEADERS Directly to Support Staff. I don't want to Post them here since someone might inadvertently Click on them and get Malware from rxvtom<.>com Malware site.

Amazing that there is no topic for Spam, the most hated aspect of email. Mozilla, wake up!

Anyway, I want to be able to highlight a bunch of spam emails, then block all the domains they are being sent from, first checking to make sure nothing was sent from a legit domain like Gmail or Hotmail. Because the smart spammers acquire domains from which they can generate an untold number of email addresses from and they can just a different one every day so blocking an individual email address from someone like this is useless. They'll never use the same one twice because it's so easy to use another one. They own the domain so they control everything at that domain.

I've never heard of any email program offering this which is perplexing as this is the only logical solution to the vast majority of spam we are plagued with in 2025.

We really need an Add-On for Thunderbird as it appears Thunderbird doesn't seem to care.

Hi, I have three email adresses installed on Thunderbird. All have Junk folders I see on screen. But while two addresses sow junk files one is all the time empty.

alors que les anciens messages sont encore lisibles. Merci

I tried gleaning this single outgoing email of "excessive spam/sales language" (I am only thanking someone for their purchase, not asking for another); "excessive links" (they and their graphics were fine before). no "excessive emailings/quantities" (I am only sending one single email and don't do more than a few with this content ever and haven't send even one email like it in weeks); co0ntacted my internet provider (RCN Astound can't help me and told me to contact Thunderbird), I already checked POP & SMTP stuff...

"Sending of the message failed. An error occurred while sending mail. The mail server responded: [VO-101] Message blocked due to spam content in the message.. Please check the message and try again."

What do I do?

I even checked that I had the latest version of Mozilla Thunderbird: yep! :/

I have turned off every junk filtering option in Thunderbird, globally and for each account, yet the application started and continues to mark nearly every incoming email I receive as possible junk -- even emails from MOZILLA... It is not my ISP, nor my email provider, as they are not filtering junk, either. The banner on the preview window says "Thunderbird thinks this message is Junk mail", so that tells me it is THUNDERBIRD that is doing this. How can I get the app to stop??? There are no helpful conversations in the forum, since I've tried all of the solutions that were presented. I'm about to just delete the app and use something else which is a shame since I've been using Thunderbird for probably 20 years, but I cannot continue if this problem does not stop.

So, all of a sudden my incoming emails went directly to the "Junk" folder for no apparent reason. When I go to the Junk folder to view my emails, they don't show up in the right viewing column.

And when I try to send them back to my "Inbox," they don't go there and I have no idea where they go. I can't see them anywhere. I've checked my outgoing settings and they're where they are supposed to be....as well as my incoming server settings. They are where they should be. I use Comcast, and have checked with them, and those settings are correct

So at this point I have no idea what to do, and obviously need help from someone much more knowledgeable then me! Hopefully I've explained the issue clearly, and have made it easier for those of you out there. I'm not a computer dummy....but this has be quite baffled, as it came on suddenly, and had weird characteristics.

Thanks to all,

Michael...

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..

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 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

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.

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!!

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.
