已有 postfix的話只作更新即可

   make upgrade

 

find /usr/ -name ssl.*

[1.] vi /etc/postfix/main.cf

smtpd_use_tls = yes

 

# RSA
smtpd_tls_cert_file = /usr/share/ssl/certs/cyrus-imapd.pem
smtpd_tls_key_file = /usr/share/ssl/certs/cyrus-imapd.pem

 

# DSA

#smtpd_tls_dcert_file = /usr/share/ssl/certs/cyrus-imapd.pem

smtps inet n – n – – smtpd
    -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes

[4.] Postfix reload

 

[5.] 測試 telnet localhost 25

ehlo xx
