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

I was searching for an email that I had just deleted and discovered that the Trash folder connected to my inbox was empty. The one connected to my Local folders, however, was not. I cannot find a setting that would instruct Thunderbird on how long to save emails in the Trash folder and am sure I did not accidentally change anything. Any idea how to fix this?

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

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! :/

Why doesn't Thunderbird block spam and junk mail? It often tells me that "Thunderbird believes this message is Junk," and I right click "Mark" and tell Thunderbird the message is "Junk," but the sender is never blocked. How many times must I tell Thunderbird that a sender is spamming me?

Why is it so difficult to block a sender who is spamming me? With other email clients, just one marking of "Spam" is enough to block that sender?

How do I tell Thunderbird to block a spammer?

Hello, I have had very good luck with junk being identified and moved to the junk folder, but now, while everything is still being identified as junk, it no longer moves to the junk folder. I have not changed settings and ocasionally some junk messages do go to the folder but then it stops and reverts to junk being identified but remaining in my inbox. Is there something I can try to get it working like it used to?

I upgraded Thunderbird a few days ago to 141.0 (64 bit). Today, I note the spam folders in both of my email accounts are missing. So where is spam email going? Is the software automatically routing it into the JUNK folder? If not, how do I resurrect my spam folders?

Hello,

I wanted to empty the trash in one of my email accounts in Thunderbird. Normally I would right click on the trash folder and then there is the option to empty the trash. Unlike ever before and on this one account (gmx imap) this option doesn't exist anymore - I can't empty the trash. I went into the account settings and ticked the option to empty the trash on exiting but after quitting Thunderbird and restarting it, the email is still in the trash.

What's wrong here? My suspicion is that I would need to mark the email in the trash as read and only then I would get back the option to empty the trash? I don't want to do that, I want to be able to empty the trash whenever I want to or on exiting Thunderbird. I don't want to be forced to mark an email as read before beeing allowed to delete it. Please help.

By the way, it was very difficult to even get to post this question here. I also don't really find this forum to be user friendly. Is this supposed to be the official Thunderbird forum? Or is that somewhere elese? Thanks.

I have TB Mobile for Android Version 8.2 on my Samsung A54 running Android 14. I have done numerous searches, but can not find any way to move an email that I accidentally sent to Trash or Spam back to Inbox (or any other folder for that matter). Am I missing something or is this feature simply not available?

I can do the above with my Yahoo mail on my A54 which has a menu that lets me move any email from folder to folder.

Thanks for any help.

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.

Bonjour,

depuis cette après midi et alors que tout marchait bien ce matin tous mes mails entrant sont systématiquement classés en spam et illisibles. Le nom de l'expéditeur et le sujet du mail ne sont plus lisibles non plus et sont tronqués.

J'ai essayé de m'envoyer des mails de test et je reçois un mail tronqué illisible. en image je vous envoie le mail envoyé et ce que je reçois. Tous les mails entrant quel que soit l'expéditeur sont traités comme ça.

Merci pour votre aide car je ne peux plus rien faire et j'ai vraiment besoin de mon mail en ce moment.

Hello, I currently have the "adaptive junk mail controls" enabled in my account settings. I have been marking junk mail as spam (the fire icon) every time one comes in my inbox and sending them to the junk folder. However, I am still getting the same junk mail. If I delete items in the junk folder every so often (I had 2,000 junk emails in there at one point and then deleted it), does this negate the Thunderbird identifying items as junk mail? What should I be doing with the junk mail once it is in the junk folder?

I tried unticking enable and it did NOT work. Help! I want the stupid filter gone. I have struggled for two years with the junk filter which does not work right. I have done shift J. The filter does NOT learn. A week aog, I saw that I could uncheck enable and that was supposed to stop the filter. That also did NOT work.

Today, an email I forwarded to myself from another platform went in junk. I never wanted any junk filter. It has been nothing but trouble and now I can't even disable it.

I am trying to whitelist a domain name. TB won't let me do that. This company has a plethora of emails. I don't want to whitelist every single one of them. That would take me days. It is impractical. I want to whitelist the domain name which is concentrix.com. I want to ensure that all emails coming from that domain name land on the inbox folder. How can I do that on TB?

Would like to save all my deleted emails in a common trash box from all my accounts. Currently, accounts are saving deleted emails in their OWN trash folders. Can I force all deleted emails into a single trash folder?

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.

I'm thinking that when I mark emails as junk, they immediately delete, but are all the junk emails suppose to keep coming back, but now only with that yellow junk banner. I was thinking that if I mark it as junk, they get deleted immediately and I don't have to keep going over them, and seeing them, but now with that Thunderbird thinks this is junk banner. But I already marked those as junk many times. Why do they keep coming back like that?

I have set a filter to move messages from a certain address to a certain inbox,. In the filter settings I tick the box that states filter before junk mail before Junk Classification. Nevertheless mail from that certain address keeps getting put in junk mail. I have in Junk Mail marked all these messages as not junk but new ones keep getting put in the junk mail box. Help
