SPF sucks.

It totally breaks forwarding. The idea to put in routing information
to deliver bounces will bring us back to the last century and it IMHO
doesn't make a difference if I use

    maex%space.net%some.example.com%another.example.com@localhost
or
  maex#space.net-maex#some.example.com-maex#another.example.com@localhost

it tosses the relay door for spammers wide open again.
