Thunderbird Community Forum

I am working on an article explaining aspects of message verification such as SPF, DKIM, DMARC and ARC. I have been studying how messages are marked as spam. I have observed that some messages that would be purely legit (like from my bank) are occasionally marked spam. Others show inconsistency -- such as my articles from Substack being marked as spam for some addresses I own, while others are not.

I am particularly interested in how Thunderbird is interpreting the header in regards to source verification. In most of my articles I have advocated for a scoring system that would better inform the recipient of the trustworthiness of the message. I noticed there is an X-spam tag on some messages that is based on a scoring algorithm.

Appreciate your assistance.

Some Junk Mail (so far, only from my Outlook mail account) is appearing in my Inbox. This mail has a yellow banner at the top stating "Thunderbird thinks this message is Junk mail". Also on this banner is a button marked "Not Junk", that allows me to tell Thunderbird that it is not Junk. At the very top of the message (as with all messages) is a button marked "Junk", which in this case is "greyed out" and so won't work, although this button is not greyed out for messages that are not thought to be Junk!. This seems counter intuitive to me. Thunderbird is allowing some messages into the Inbox which it thinks are Junk, but disables the button that allows me to confirm it! I know that I can still mark the message as Junk by using the individual menu for the message (3 vertical dots), but why disallow the obvious "quick action" button?

Under my main email account in Thunderbird there are two Spam folders. I don't know how a second one was created but I'd like to delete it. When I right-click each Spam folder, only one has a Delete option, but when I select it, the Spam folder doesn't get deleted. How can I delete the extra Spam folder? thanks.

I have a domain so any email I use comprises of name@mydomain.co.uk

In the past I have given an email address to some dodgy enterprises such as Abbey National plc, and so I get loads of spam to abbey@mydomain.co.uk

It is an utter pain that many spammers use a throw away or random To: address but because the envelope email is abbey@mydomain.co.uk I get to receive it and there is no easy way of searching a folder to find matches to "envelope to".

Similarly it seems impossible to construct filters for an "envelope to" address.

Any ideas?
