There have been a few bogus subscription successes but the forged From
autoreplies we're seeing are the vast majority of the problem.
I started bouncing email to gcc.gnu.org with executable attachments at
the [sq]mtp level yesterday. Prior to that, I turned off bounces
to certain classes of "spam", like invalid mime type.
I've been tweaking the filters like mad so that everytime I see YA
variation of "Your email has a virus" in a subject, it is blocked.
It's been an interesting couple of days at gcc.gnu.org...
