Hello,
I’m using Apple Mail on Mac OS Big Sur
My SpamSieve is not trained a lot on my MacBook Air.
So The Spam Sieve filter delete a lot of my new messages.
Yes I said deleted, the emails are not on any in the spam folder or in the trash.
That’s the case for all my mailboxes.
I checked the log file and indeed a lot of emails are notified as spam.
I never modified the filter here:
How to find the deleted messages by SpamSieve?
SpamSieve doesn’t actually move or delete anything. What happens is that Mail evaluates the rules and sends the message to SpamSieve for analysis, SpamSieve tells Mail that the message is spam, and so Mail applies the rule’s actions.
Normally this should do exactly what it looks like (in this case move the message to the location that you specified and mark it as read), but there is a bug in some versions of Mail where in some situations it will delete messages instead of moving them (either via rule or otherwise). It looks like this may be what’s happening here. We recommend that the rule should move the messages to the All Junk mailbox:
It’s also possible that this is not the reason that you aren’t seeing the messages. For example, they could have been moved out of the Junk mailbox by another computer or phone or auto-deleted by the mail server or Mail if it thought they were old.
Going forward, I strongly recommend changing the rule in Mail to use All Junk and setting Mail to store each account’s Junk mailbox on the mail server.
Lastly, you wrote that SpamSieve was “not trained a lot,” but the screenshot shows that it was trained with 1,619 spam messages, which is about 10× more than is necessary for good filtering. I wonder if part of the problem is that it was trained with lots of spam but not many good messages (that number was not shown in the screenshot). There’s more information about the recommended training here.
