Thunderbird Community Forum

Over the last week or so, I have received an enormous amount of scam, but no matter how many times I "train" the filter, it doesn't work.

I have just received another 3 from this site: mid:02guhjkj6-ABMcSHN6Or-JiC-000000@eu-central-1.amazonses.com, which claim to be from Madasafish Security>security@qi9adgongzenElptrum.de

I have tried on several occasions to follow the manual instructions how to deal with the spam, but I find it so log-winded that my non-techie brain, which is not wired for these kind of things, gets tired and I give up. If anyone has a more intuitive approach how to deal with this, I would be very appreciative. I have marked sites multiple times as spam, but the spam control ignores me!

Is there a spam file for thunderbird? I haven’t been able to find one. Xfinity has a spam box on my site. I had mail sent to me and could not find them on thunderbird or Mac mail but I Katerina found them in the xfinity spam folder..

is there any way old emails can be retreived after deleting them to the bin. I thought sending them to the bin folder still retained them in archive status, but trying to look back more than the 3 months current in & out boxes They don't appear to be there

Subject: Thunderbird 152 – IMAP Junk messages are not automatically moved to Spam (T-Online IMAP) I am using Thunderbird 152 on Windows 11 with a Deutsche Telekom (T-Online) IMAP account. Problem When I manually mark a message as Junk (toolbar button, context menu or Junk column), the message briefly disappears from the Inbox and immediately reappears. It is marked as Junk, but it is not moved to the Spam folder. If I disable the option "Move new junk messages to:", the message remains in the Inbox and is marked as Junk, without the brief disappearance. Manual Move to → Spam always works correctly. Environment • Windows 11 • Thunderbird 152 • T-Online IMAP • ESET Internet Security • Only one Spam folder exists on the T-Online server. Troubleshooting already performed • Created a completely new IMAP account. • Verified Junk settings. • Verified the Spam folder path: imap://...@secureimap.t-online.de/Spam • Manual move to Spam works correctly. • Rebuilt the folder cache. • Recreated folderTree/folder cache files. • Performed IMAP resynchronization. • Tested with ESET mail protection enabled and disabled (no change). • Checked profile configuration. • Verified that the IMAP server directory setting does not change the behaviour. Additional observation The profile contains two IMAP cache directories: • secureimap.t-online.de • secureimap.t-online-1.de The current IMAP directory does not contain local Spam/Junk cache files, while the old "-1" directory still contains: • Spam • Spam.msf • Junk • Junk.msf Thunderbird also displays a greyed-out, inaccessible Spam/Junk folder which cannot be selected, subscribed or removed. Question Is this a known issue in Thunderbird 152 related to IMAP Junk handling or old IMAP cache migration after changing an account from POP to IMAP? If not, which log or additional information would help identify the cause?

PS: The POP account worked correctly before the migration to IMAP. The problem started only after switching from POP to IMAP. Rudolf.weinzierl-landshut@t-online.de

Let me explain there is some one with the following email:

Whatever anyone does do NOT click on their links I believe it's a criminal organization trying to get to my account.

I know many of you may not be in my situation but I'm a bit job hungry cause financial hit really hard. I clicked on link without looking and the site pretended I needed to fill a job application out. So I did without looking to see who sent it. Yes, STUPID me.

For some reason I marked as junk and it's not going to where I need to and that is trash and immediately delete it. I try and see if I can setup a rule for that. But wondering if there a extension that might do a better job. I tried to unsubscribe but these guys keep hitting back. That one sign of hackers trying to penetrate.

So now I'm wondering is there anything else I might be over looking. One think I keep thinking about is why NOT put something a tool that will do similar to mxtoolbox. With AI out there it's going to get harder to keep these criminals out of our inboxes.

I appreciate any feedback.

I have used Thunderbird for years and years and never had a problem. The last 2 weeks all of my outgoing emails have been going to everyone's SPAM folders. I have an AT&T email account and I use the AT&T Pop server settings, for the Outgoing Server I have the Comcast/Xfinity settings. I receive emails with no problems, it is my outgoing emails only. I don't know if it is a Comcast problem, an AT&T problem or Thunderbird problem. I have been on the phone with Xfinity for 2.5 hours and still having problems. Any suggestions.

Guten Tag,

Ich hoffe Ihr könnt mir helfen.

Ich benutze Thundebird das erste mal und würde gerne wissen wo meine gelöschten Mails hin verschoben werden wenn wie auf dem angehängten Bild keine Einstellung vorgenommen wurde standardmäßig. Werden die Mails dann direkt gelöscht aus der kompletten Mail-Adresse oder bleiben diese irgendwo gespeichert?

Die Gelöschten Mails sind im Mail Konto nicht mehr auffindbar.

Viele Grüße

The sent message is deleted but I get Filter action Failed.

I am getting a lot of email dated a month of more in the future. How do I best filter these out as junk? I tried making a regular filter, but can't find a way to set it to "greater than today."

A category (Daily Brain something) of emails that are clearly spam (you even think they are spam) are landing in my Inbox every day. I have my email set to not allow emails from any addresses that aren't in my book. If I follow their 'unsubscribe' link, I just get more of them. This is the latest one: ar849137@ocotille.com with a Reply To address of: 3527_rep_Y2pnZGVzaWduc0BlYXJ0aGxpbmsubmV0@ocotille.com Every one is different. Why are these getting through? Thanks Cary

Despite my marking messages several times as NOT spam, Thunderbird keeps on and on RE-marking them as spam. And the mails are coming from one of my own addresses, and they ARE in my address book!!!!!

There seems no way that I can stop the beast from misbehaving.

I have 6 email accounts linked to Thunderbird. I noticed today on one of the accounts, along with inbox, drafts, sent, etc., there is now a spam icon. I didn't change any settings or even look at that email account today. This is the only account with that icon and it won't allow me to delete it. All settings between all accounts are the same, just this dang spam fire icon that I can't delete

When I get spam email in my inbox, I mark it as SPAM. It will arrive again in a couple of days. Why does it come into my in-box still? Its marked as SPAM in my In-BOX!

I don't want to keep touching junk email!!! its a huge waste of time. I cannot find the settings on how to make that action happen.

Please advise. If this isnt possible I will unfortunately be leaving your platform after decades of use. Yes I have donated several times over the years. Not get rich money, but it all helps.

Since yesterday (27 Apr 2026) any and all mail that comes into Thunderbird gets marked as SPAM. I searched online and found people saying that I could reset the junk training filter, so I did this, but incoming mail was still marked as spam. The next suggestion was to delete the training.dat file. Did that, restarted Thunderbird and incoming messages are still marked as spam. The last suggestion was to turn off adaptive junk mail controls. Didn't want to do that because I assumed that it would let spam through. Nope. Turned it off, restarted Thunderbird and two emails from my work came in and got flagged.

I'm running version 140.10.0esr (64-bit) on Windows 11. I am using IMAP to connect to the mail server but it's not running any spam detection software (like Spamassassin). I know this because it's my server and even if it was, no updates have been preformed since the first of this month and this just started happening yesterday. Combine this with the bug that Thunderbird notifies me of incoming mail, even if it's spam (didn't post about this because there are plenty going back a couple of years), is starting to make me look for an alternative.
