我使用本指南为一家小型企业创建了邮件服务器：https://workaround.org/ispmail/wheezy。IMAP 运行正常，但我遇到了 SMTP 和经过身份验证的 SMTP 问题。当我使用电子邮件客户端（Inky、Airmail）时，我从 IMAP 连接中获取日志，但没有从 SMTP 获取任何日志。最奇怪的是，如果您在手机上使用我的蜂窝服务，它就可以正常工作……

有人和我遇到同样的问题https://workaround.org/ispmail/wheezy/authenticated-smtp/#comment-2995
答案1
将 permit_sasl_authenticated 添加到 smtpd_client_restrictions 并查看它是否有效。
