If you mean this:

Received: from hacker (ppp-171-74.30-151.libero.it [151.30.74.171])

That's not a mailbox name, but a (faked, obviously) hostname,
probably the one provided on the EHLO line to the SMTP server where
he injected this mail. Which would appear to be running:

          by xticket (2.5 Build 2640 (Berkeley 8.8.6)/8.8.4) with SMTP

The validity of that IP address is also questionable, but it might
be worth getting in touch with the good folks at libero.it and
seeing who was connected to that slot on their dial-up box at that
time. (It's almost definitely a stolen account, of course.)
