The latter, most likely.  The guy is looking for a cgiemail binary 
specifically (or possibly a formmail.cgi) that doesn't completely 
strip ALL header fields.  This was published as a vulnerability of
cgiemail, but when cgiemail is configured right the exploit fails.

(I let ONE of these through a few months back, then closed it up,
and the little idiot kept hammering it for weeks afterward.  He
was targetting AOL exclusively, and my contact at AOL Security
indicated they'd squash him like a bug. I haven't seen any signs
of that...yet.)
