在 thunderbird 自动连接中没有检测到任何东西，然后我手动设置但没有任何功能
答案1
在 master.cf 中我取消注释
smtps inet n - n - - smtpd
-o smtpd_tls_wrappermode=yes
-o smtpd_sasl_auth_enable=yes
-o smtpd_client_restrictions=permit_sasl_authenticated,reject
-o milter_macro_daemon_name=ORIGINATING
在 iptables 上允许端口 465，现在可以运行
SSL 上的 Postfix 没有使用端口 25？
