I just upgraded my Ubuntu server to 13.04, and I can no longer use spf-milter (http://acme.com/software/spfmilter/) which used to reject mail that fails SPF.
I was also using milter-greylist (which is awesome by the way, so thanks for this).
Now I read that milter-greylist supports SPF, but I wanted to know if it cold reject mail based on a failed SPF.
