Saya terapkan greylist sesuai petunjuk mas asfik di
http://www.mail-archive.com/postfix-users@postfix.or.id/msg00731.html
namunsetelah saya cek lognya ada pesan
postfix/smtpd[26890]: warning: unknown smtpd restriction: "greylist"
Yang dipake itu
smtpd_restriction_classes = greylist
Atau
restriction_classes = greylist
Soalnya kau cek dengan perintah postconf | grep restriction_classes yang
muncul Cuma
smtpd_restriction_classes =
Ini perubahan pada main.cf
================================
smtpd_recipient_restrictions =
permit_mynetworks,
permit_sasl_authenticated,
# reject_non_fqdn_hostname,
reject_non_fqdn_sender,
reject_non_fqdn_recipient,
reject_unauth_destination,
reject_unauth_pipelining,
reject_invalid_hostname,
reject_multi_recipient_bounce,
reject_unknown_recipient_domain,
reject_unverified_recipient,
check_sender_access hash:/etc/postfix/maps/sender_access,
check_recipient_access hash:/etc/postfix/maps/access,
reject_rbl_client opm.blitzed.org,
reject_rbl_client list.dsbl.org,

restriction_classes = greylist

Unfortunately, some major sites such as YAHOO do not reject unknown
addresses in reply to the RCPT TO command, but report a delivery failure in
response to end of DATA after a message is transferred. Postfix address
verification does not work with such sites.

Pasang policyd (policyd.sf.net), greylist untuk domain yang anda anggap
menjadi spam source.
