There's no automatic way to know what rule did the moving. You could move
the message back to the Inbox then manually run your rules one by one to see
which one did it.

Also, are you using the built-in Junk E-mail rules?

I turned on junk mail filtering recently after the number of identical
software spams I started receiving escalated from just a few to a few
dozen on average every day.

But the problem pre-dates that.

It is always the same people whose emails keep getting deleted even
though there is nothing obvious about their email addresses or the
content of their messages which would account for them being deleted.

I suppose a bandaid solution would be to create another rule which
moves their emails from the deleted folder to the inbox, but would that
create a new problem where their emails would effectively become
undeleteable while the rule is active?
