BIND does support the SPF type. Note however that the latest draft version of SPF actually deprecates SPF, and recommends using TXT records: 3.1. DNS Resource Records SPF records MUST be published as a DNS TXT (type 16) Resource Record (RR) [RFC1035] only. The character content of the record is encoded as [US-ASCII]. Use of alternate DNS RR types was supported in SPF's experimental phase, but has been discontinued. See Appendix A of [RFC6686] for further information. http://datatracker.ietf.org/doc/draft-ietf-spfbis-4408bis/?include_text=1 -- Shane _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
