Perhaps what's needed is an optional second argument to 'spf = xxxx',
with the same syntax as 'spam = ' ...
spf = xxxx : helo
spf = xxxx : mfrom
... preserving the existing behaviour if the second argument is
missing, of course.

I agree, it probably should be supported. I just mocked up the
Mail::SPF HELO check, seems to be functionally OK, but performance is
a worry.
