Thunderbird Filter: When reply to (returnpath-email) domain do not match the senders email domain.

[Shawn64]

To encourage good corporate governance and email usage - and minimize spamming and criminal activity

When at least two elements (starting from the back of the domain do not match) do something, move it to a different folder, let us mark it as low priority or suspicious (another priority I would like to see.)
It must work from back to front.  The minimum matches must be two: the dot com and the next one up.

Keep in mind the ' something AT gmail.com'  was/is an old standard for email addresses.  I have not seen one in years.

https://mailtrap.io/blog/returnpath-email/      Return path is optional but it could be used to criminals to determine if a email address is valid.  Note the return path could be used to determine phishing expeditions, if they don't match I would want to know someone actually sent it, perhaps this is 'another filter'.  This is up for discussion.

If something comes from whatever@discover.com

it is bad if it has @discover.com.spam.net

it is bad  if it has @discover.net

it is OK if it has @return.discover.com

it is Ok if it has @disney-promotion2023.discover.com

it is bad if it has @discover.disney-promotion2023.disney.com

If it is from gmail.com  I don't know what to do but at least it would pass first hurdle.  BUT if sender and reply to don't match  disney@gmail.com      reply to kingsdominion.disney@gmail.com it should be italicized or something - allow us to manage that part somehow.

Thanks.
