ouch. if you don't pass in a meaningful sender, Mail::SPF::Query will

BTW this seems to work very well indeed:
2.815 0.0000 3.0571 0.000 0.92 -0.10 T_SPF_PASS
0.063 0.4577 0.0295 0.939 0.74 0.10 T_SPF_FAIL
3% of nonspam gets SPF "pass", 0.45% of spam gets "fail" -- which isn't
bad, given how early in the stdization process it's at.
Ignore the 0.0295% -- that was an error in my own SPF setup, cough ;)
So how naughty is it to use HELO data instead of MAIL FROM for the
SPF check? ;)
