TODO: - Review handling of incoming mail to lists.gentoo.org for SPF compliance. - Decision on non-pass match of @gentoo.org email. - Be mindful of ~all records vs -all. Proposed actions: - strongly encourage all developers to either relay or add their own SPF rules with a strict '-all' policy. - Deploy qpsmtpd for programmatic customization in SPF validation on lists.g.o -- be very strict about mail from @*.gentoo.org -- potential policy: require GPG against known LDAP keys || strict SPF.
