当我尝试通过 POP3 和 Postfix 发送邮件时，出现 NOQUEUE：reject：RCPT 错误（注意：IMAP 工作正常）。

SSL 和其他一切似乎都正常工作，只是出站 POP3 不会发送到 Gmail，我正在 Outlook 上测试，并且选择了端口 587 的 SSL

您的 Outlook 邮件客户端，如图所示： Outlook 身份验证

是不是设置为使用 SASL 身份验证。Outlook 的“发送服务器”对话框可能不是自解释的：“发送邮件前登录到接收邮件服务器”意味着不是SASL 进行身份验证，但优先使用 POP。但是，您的 Postfix 设置需要 SASL：

smtpd_client_restrictions = permit_sasl_authenticated

从你的问题中看不出你想做什么。如果你真的想要 POP-before-SMTP，你需要运行一个守护进程（如 pop-before-smtp）来读取你的邮件日志并将 IP 地址添加到 postfix/smtpd 读取的 db 文件中，如下所示：

smtpd_client_restrictions = permit_sasl_authenticated, check_client_access hash:/var/lib/pop-before-smtp/pop.db

否则，只需选择“使用相同设置...”作为邮件客户端中的身份验证方法并使用 SASL。
