Dear postfixer,
Gimana caranya kita reject email dengan alamat palsu. Soalnya saya banyak
terima spam dari [EMAIL PROTECTED], padahal setelah saya cek di yahoo email
tersebut tidak ada.
Saya udah terapkan policy seperti ini
smtpd_sender_restrictions = reject_unverified_sender
http://www.postfix.org/ADDRESS_VERIFICATION_README.html
...
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.
Dan
smtpd_recipient_restrictions = permit_mynetworks,
permit_sasl_authenticated,
reject_non_fqdn_sender,
reject_non_fqdn_recipient,
reject_unauth_destination,
reject_unauth_pipelining,
reject_invalid_hostname,
reject_multi_recipient_bounce,
reject_unverified_recipient,
check_recipient_access
hash:/etc/postfix/access,
reject_rbl_client opm.blitzed.org,
reject_rbl_client list.dsbl.org,
reject_rbl_client bl.spamcop.net,
reject_rbl_client
sbl-xbl.spamhaus.org,
permit
Tapi saya lihat dimailbox saya masih menerima email palsu tersebut.walaupun
sebenarnya terdeteksi sbagai spam tapi alangkah baiknya langsung direject
dari postfix bukan oleh amavis.
Pasang policyd (policyd.sf.net), greylist untuk domain yang anda anggap
menjadi spam source.
