The "Network objects should not contain host bits" is a warning that comes from the underlying library used to validate IP addresses and IP networks. Since the SPF RFC describes this as being either an address or a network, a warning is surfaced for oddly-formed network expressions. If I'm reading this too narrowly, by all means, please let me know! I'm happy to suppress this the information is unnecessary (as perhaps the receiving world's SPF stacks simply don't care). =- Tim _______________________________________________ dmarc-discuss mailing list [email protected] http://www.dmarc.org/mailman/listinfo/dmarc-discuss NOTE: Participating in this list means you agree to the DMARC Note Well terms (http://www.dmarc.org/note_well.html)
