Well, most mail servers will reject such a server (i.e. one with NO rdns). However, there's another possible interpretation of your request. SPF records go in the zone of the envelope-sender. So if your server's ip is 72.9.101.130, and your mail address REALLY is b...@130.101.9.72.in-addr.arpa, then the reverse zone would also need to have an MX and possibly an A record, in order to route mail to it, which goes a far cry from being "a server that has no entry in the DNS". I can't even imagine what spamfilters would think of such an address. :) -Dan Mahoney _______________________________________________ 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
