介绍
警告 ！
我知道，这个问题已经被问过了。但是结果对我没有帮助，所以我将我的错误详细说明给你。
我的演说
您好，我是一名 IT 科学专业的法国学生，我正在参与创建电子邮件服务器的项目！
我过去在发送和接收邮件时遇到了几个问题......
今天的结果
现在我又遇到了发送和接收邮件的问题！
但我在 SSL/TLS 中，所以 IMAP 端口是 993，SMTP 端口是 465。
为了创建我的电子邮件服务器，我使用 postfix 和 Dovecot。对于域名，我使用 NoIP。
保密问题，域名为：cookie.ddns.net，邮件域名为：cookiemail.ddns.net。
在 NoIP 中，我在 cookie.ddns.net 中添加了一个 MX ，即cookiemail.ddns.net。
服务器在 Xubuntu 上。

在 mynetworks 变量上添加 [::1]/128
当我收到一条消息时，我遇到了这个错误：
NOQUEUE: reject: RCPT from mail-40131.protonmail.ch[185.70.40.131]: 451 4.3.5 Server configuration error; from=<xxxxxx@protonmail.com> to=<admin@cookie.ddns.net> proto=ESMTP helo=<mail-40131.
protonmail.ch>
但是当我编辑我的 /etc/postfix/main.cf 时：
smtpd_recipient_restrictions = permit_sasl_authenticated,
#check_recipient_access,
#permit_mynetworks,
#reject_unauth_destination,
#reject_unknown_sender_domain,
#reject_unknown_client,
#permit
我没有这个错误，我有：
