So, it looks like postfix/libmilter is passing some garbage for
hostname.  Here is the API:

  http://pythonhosted.org/pymilter/milter_api/xxfi_connect.html

I'm not sure how we can detect that to work around it.  Possibly the
libmilter you are using is the problem.  Are you using libmilter from
postfix?  Or from sendmail?   Try using libmilter from sendmail.  It
should still work with postfix.
