It's not that bad because they're in reverse cronological order, and
the one you want to look at is always in qmail-smtpd's format, and
it's the second Received field.

No, Received fields aren't randon junk. You can trust the ones added
by qmail.

Nothing easier that parsing the Received fields. E.g., it took me
about a minute to come up with:
822field received <msg|sed '1d'|sed '2,$d'|sed 's/.*(//'
Which uses 822field from DJB's mess822 to extract the IP address of
the sending host from a message.

It's great. I've received almost no spam since implementing it. The
only spam that's gotten through has gone through our "helpful" relay
which "fixes" unqualified addresses by tacking on "ornl.gov", which is
on my whitelist, of course.
