我启用了 smtps，因为我认为那是问题所在，但它仍然不起作用。这是 mail.log 文件：

这与我的网络无关，那么问题是什么呢？
编辑：我的似乎出了问题main.cf，一旦我将其恢复为默认值，一切就都正常了。
答案1
是的，它拒绝端口 587，因为整个部分都master.cf被注释掉了。
#submission inet n - - - - smtpd
# -o syslog_name=postfix/submission
# -o smtpd_tls_security_level=encrypt
# -o smtpd_sasl_auth_enable=yes
# -o smtpd_client_restrictions=permit_sasl_authenticated,reject
# -o milter_macro_daemon_name=ORIGINATING
如果您希望 Postfix 通过此端口接受邮件，请取消此项注释。
答案2
我想补充以下内容。
在 Plesk 12 上，执行不是取消注释/编辑顶部设置。Plesk 将在 的最底部添加所有配置设置master.cf。您可以编辑它们，然后按postfix reload。
我希望这会对某些人有所帮助..我搜索过的所有论坛/ KB 文档都告诉您取消注释顶部设置...
