Revers lookup might fail and some secure smtp server and other daemons do not allow access if reverse lookup failes. For example: sux IN A 192.168.0.1 mustdie IN A 192.168.0.1 in the reverse zone we say 1 IN PTR sux nslookup mustdie gives 192.168.0.1 nslookup 192.168.0.1 gives 'sux' Artem To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
