None of that junk in my mailboxes or in:

As such, you might want to check headers...

The primary filter for spam is that one has to be subscribed (to the
right list). This only fails the moment a spammer uses a correct From:
header, which happens, sometimes, but very rarely.

And if that happens, then your local spamchecker should be more than
able to filter that crap out before you see it, especially with such
obvious subjects (though you didn't show the headers nor content...).
