Just in the last two days I've been seeing an extraordinary amount of
bad SSL traffic on my mail server. So, even it Heartbleed wasn't
exploited before, it's sure being exploited now.

By "bad SSL traffic" I mean SSL connection requests that disconnect
immediately or time out without initiating any kind of SMTP
transaction. I haven't noticed an increase in bad non-SSL traffic.
