Remove addresses from spam / junk mail list
I have for some time been teaching the spam filter in OSX Mail by hitting the "thumb down"-button on messages that are spam.
Unfortunately I have a few times hit the button by accident on people who are NOT sending spam. So I have to remove them from the spam list. But I cannot find a place where the spam list can be edited.
I have read on this forum that the spam filter does not store addresses, but work in another way. That sounds strange, because I know positive that friends (even on my address list ) sending me emails that are not spam. In it does not appear on my computer.
I have a second computer on which I have never been teaching the spam filter. Here the mails get in. But a lot of spam too, of course. It is therefor tempting to conclude that there is actually addresses that are stored in the filter.
Thanks for any help here.
