url flagged as malware in thunderbird
I manage deliverability & anti-abuse for Mailjet SAS, a transactional email service provider.
mj.am is one of our trackhost classifiers. My Support Team received an escalation a few moments ago stating that mj.am is flagged as malware in the Thunderbird client.
Can you kindly: - share header information associated with the malicious message your servers received? - kindly delist the negative/bad classification for mj.am?
Thanks in advance. I am at your disposal for any questions.
Thanks!

I think you best talk with your customer more. Thunderbird does not identify URL's as malware. It has very basic scam detection that most turn off. But it uses no lists or databases, it simply looks at the URL used and any attempts that may have been made to obscure the true URL used from the user.
As Thunderbird source is open, your technical folk can examine the phishingdetector.js file to their heats content. IF they want to offer to improve it, their contribution would also be welcome, within the patch submission guidelines. For many years there has been a desire to improve what is really a very poor tool, but there are no resources to do so, The use of web based tracking tools for email clickthroughs is however a very controversial topic n the Thunderbird developer community. German privacy standards are the basis for anything.that might get through the approval process.

I'm looking further into this, thanks Matt!
