Indeed.

He's almost certainly been spammed by a friend's system.  Lots. It's
seldom obvious, and usually indirect, but the reality is that once a
machine is owned, just about _anything_ can happen.  Why haven't they
been "getting around" SSL and S/Mime?  Because they haven't needed to

"solution" that uses them becomes common and popular, it _will_.
