Or are you talking about Thunderbird? https://support.mozilla.org/en-US/products/thunderbird

Sorry that's not helpful FredMcD I'm using Thunderbird, and the 2 questions the link led to just posed more questions to me that I didn't know the answer to. I have had a filter for some of these addresses. I re-installed Thunderbird and it was deleted. I've set up another and it's not working, everything from those addresses (and others that I'd like to receive and never set up filters for) goes into junk.

You say that you are using Thunderbird, so FredMcD gave you the correct link :

https://support.mozilla.org/en-US/products/thunderbird

When you click on the 'Ask a Question' at the top of the page, you can post your question there (on the Thunderbird support forum).

The reason I told you to contact your e-provider is different providers also provide different bells and whistles.

In the case of my provider, addresses/domains blacklisted addresses/domains whitelisted sorting of incoming emails to folders emails from unknown sent to junk folder

and so on.

Thanks Tania

Yay  ! Glad you've got that problem solved  !

Would you be a dear and mark your last post as Chosen Solution  ?

Should you ever get another email related problem ('hope not - fingers crossed  !) - you now know how to post a question on the Thunderbird support forum .....
