Status: RESOLVED INVALID

Description

[Alex]

Attachment: Dectected fraudulent. False positive.

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/95.0.4638.54 Safari/537.36 OPR/81.0.4196.31

Steps to reproduce:

Hello,

It's annoying, the new version 91 of Thunderbird detects almost all my mails as fraudulent....
Even Mozilla mails are considered fraudulent!

I have disabled everything. Spam detection and fraud detection.
Nothing works, Thunderbird keeps declaring my mails as fraudulent!

It's getting exhausting, I'm considering changing my email client.
Every time I do a major upgrade, it's always the same series of problems...

Win7 Pro SP1 x64
Intel Core i5 x4
RAM DDR3 4GB * 2 (8GB dual channel)

Hello,

It seems that the troubleshooting mode solves the problem...

Generally a good idea to test troubleshoot mode.
I vaguely recall we've had a bug report about this in the past.
Which add-on is causing this for you?

Comment 9

[Alex]

If I disable the add-ons in "normal" mode, the problem is unchanged...

Hello,

After several manipulations, I noticed that the MailHops add-on is responsible.
You have to deactivate the country filter.

Sorry for the inconvenience, I'm not used to looking at add-ons yet...

Thanks for everything!
Alex.
