Padahal dia sendiri tidak punya reverse dns lookup

y...@ubuntu:~$ host -t ptr 202.47.64.26
Host 26.64.47.202.in-addr.arpa. not found: 3(NXDOMAIN)

Moga2 kena karma :)

  

hehe gak perlu sampai segitunya pak :)
mungkin belum tau kalo efek nambah 
reject_unknown_reverse_client_hostname di smtpd_*_restrictions lebih 
banyak false positif nya ketimbang ngilangin spammer yg nggak punya 
reverse dns :D.


makanya untuk amannya lebih baik dari sisi kita yg selalu melakukan 
standarisasi. yg ada di RFC.

think positif aja.
