What he said. My mail server isn't very good at telling one return code from another so once a week I run a dedicated script on each DNSBL I use to make sure it does return a reasonable result for 127.0.0.2 and no result for 127.0.0.1. If it doesn't, I stop using it. R's, John PS: See RFC 5782. _______________________________________________ mailop mailing list [email protected] https://list.mailop.org/listinfo/mailop
