All valid questions. Lets see, i currently have sendmail doing the
headers and also doing the checks, though i may move this out in favor
of spfmilter doing it, tho i prefer c to perl for performance. I was
really looking for alternative approaches to my sendmail-spf
implementation, as i have some other checks (i.e. sid-milter and
dk-milter) checks i wanted to do the same thing for if possible.
