A rule like "ALL EXCEPT UNKNOWN" will not permit connections from bad-rdns hosts, but there's nothing that will stop them afterwards. You need either sendmail: ALL in /etc/hosts.deny or sendmail: PARANOID. Debian did have "ALL: PARANOID" in /etc/hosts.deny for a while, maybe this is what has changed for you? -- Jon Dowland -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
