建了兩台email server, 一台做主機IP:123.123.123.123, 一台做備機IP:456.456.456.456 兩部機器原來就都可以寄信 第一步就是去DNS管理中心像我是在godaddy, 選到your-domain.com加個MX紀錄給備機 MX mx2.your-domain.com 接著開始設定main.cf , 把##########下面這些加進去 不過要注意這些參數有沒有和原來的重複, 有的話加#把原來的停用 備份機 /etc/postfix/main.cf ########################################## relay_domains = your-domain.com myhostname = mx2.your-domain.com mydestination = $myhostname, mx2.your-domain.com , localhost, localhost.localdomain, localhost relay_recipient_maps = hash:/etc/postfix/relay_recipients #啟動TLS加密 這個我有買ssls.com的 ssl網頁加密, 直接用就好了 smtpd_tls_cert_file=/etc/ssl/mx2_your-domain_com_key.crt smtpd_tls_key_file=/etc/ssl/mx2_your-domain_com_key.txt smtpd_tls_security_level=may smtpd_tls_protocols = !SSLv2, …
