Solusi

Bila anda belum menyetting SSL bisa menggunakan self-signed ataupun commercial SSL (Comodo, Symantec, Geotrust), disini kita akan menggunakan self-signed SSL.

mkdir /etc/postfix/ssl;
cd /etc/postfix/ssl;
openssl req -x509 -nodes -newkey rsa:2048 -keyout mail.DOMAIN.com.key -out mail.DOMAIN.com.crt -nodes -days 3650

di /etc/postfix/main.cf tambahkan

smtpd_use_tls = yes
smtpd_tls_auth_only = yes
smtpd_tls_cert_file = /etc/postfix/ssl/mail.DOMAIN.com.crt
smtpd_tls_key_file = /etc/postfix/ssl/mail.DOMAIN.com.key
smtpd_tls_mandatory_protocols=!SSLv2,!SSLv3
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
 
# bagian ini yang sign email
smtp_tls_security_level = may
smtpd_tls_security_level = may
smtp_tls_note_starttls_offer = yes

restart postfix lalu kirim ulang email anda.
