Help! Thunderbird marks messages as junk!

A reader needs help with disappearing emails:

As of the past month or so, I’ve not been getting emails that I get on a regular basis.  A few have come back but some haven’t – Nextdoor for one, those from a Veterinarian, and only a few from you now and then (used to get many from you).  I have Thunderbird (Windows 10) and they recently updated to 115.

I had been pretty satisfied with them until recently.  Things keep changing (format, those that I mark as Junk keep coming back, and after deleting an email that’s legit, some will go into the Junk folder.  Not sure what’s going on, but I’m getting more and more disappointed with them.  Any idea what’s going on? “

If emails are flagged as junk it could be related to the spam filter on your email provider – Outlook, Gmail, Yahoo, Frontiernet, etc… You may want to open up the web app for your email and check the spam settings and also make sure to add the emails of legitimate senders to your contacts.

If you are deleting emails from legitimate senders before opening, that can also make your spam filter think that you don’t actually want to receive that message. Make sure to open and also mark as “not spam” or “not junk” if they do end up in that folder.

Let’s look at how to adjust the spam filters in Thunderbird. Click the three-line menu icon at the top and choose “Account Settings” from the drop-down menu.

Click on Junk Settings.

If you enable adaptive junk mail controls, you’ll have to train Thunderbird to identify junk mail by marking all of your messages as junk or not junk. You could also try unchecking the adaptive junk mail controls to see if that helps.
