...
# for seednet SMTP server
relayhost = [tcts.seed.net.tw]:25
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/saslpasswd_seednet 

建立連線密碼檔

新增 /etc/postfix/saslpasswd_seednet

tcts.seed.net.tw yourid@seed.net.tw:yourpassword

建立加密檔

# postmap hash:/etc/postfix/saslpasswd_seednet 
# chmod 600 /etc/postfix/saslpasswd_seednet /etc/postfix/saslpasswd_seednet.db

重啟服務

service postfix restart

使用 Godaddy SMTP

編輯 main.cf：

# for Godaddy SMTP
relayhost = [smtpout.secureserver.net]:3535
smtp_sasl_auth_enable=yes
smtp_sasl_password_maps = hash:/etc/postfix/saslpasswd_godaddy
smtp_sasl_type = cyrus
#smtp_sasl_mechanishm_filter=digest-md5
#smtp_use_tls = yes
smtp_sasl_security_options = noanonymous

建立密碼檔 saslpasswd_godaddy

smtpout.secureserver.net your@domain.name:thisispass
