Milter-greylist

Thanks for taking time to review my patch.  It sounds like your notes
about EXF_SPF could be the basis of "So you want to add <blah> support
to milter-greylist"...  However, I'm merely a user of milter-greylist,
not a hacker of it, so I've only done enough to make my own pain go
away.  If the consensus is that having DRAC support is useful to
others, then I'd appreciate having someone more conversant in
milter-greylist integrate it in a manner consistent with the rest of
the code.

It looks like sendmail protects itself by using Berkeley style locking
if available, fcntl locking otherwise.  That looks like another
autotools check to do it in milter-greylist.  Not sure whether
sendmail opens its DB files every time or just flips the lock on and
off as needed.
