I am thinking that from a security standpoint, the preferred methods of whitelisting would be by: 1) rDNS 2) IP 3) sender simply because spoofing a sender is easiest and spoofing rDNS is the most difficult.
Is this correct? Are there other considerations? -- -Eric 'shubes' _______________________________________________ spamdyke-users mailing list spamdyke-users@spamdyke.org http://www.spamdyke.org/mailman/listinfo/spamdyke-users
