在最后一天，我正在寻找这个问题的解决scheme：
我的后缀（+ dovecot）configuration完全能够接收电子邮件，并通过IMAP提供服务，但它通过SMTP（端口587）接受它们失败。
我已经尝试将example.net添加到relay_domains ，但由于它已经在虚拟邮箱域数据库中，所以失败了。
我已经尝试将mail.example.net添加到虚拟邮箱域数据库。
为了build立起来，我遵循了Ars Technica关于build立电子邮件服务器的指南。 也许会认识一些元素。 注意：由于缺lesspostfix-dovecot包，我无法完全按照指南操作，但是我认为我已经克服了潜在的问题，因为我可以接收邮件。
进一步注意：发送到其他地址（如[email protected]）确实有效。
我可以提供任何所需的文件。
如果需要：后缀版本2.11.3
请注意：example.net是我的域名的替代品。 这是有效的，DNS设置和有效的TLS证书安装。

拒绝是由smtpd_recipient_restrictions引起的。 从smtpd_recipient_restrictions删除reject_unauth_destination应该可以解决问题。
您已经将reject_unauth_destination放入了smtpd_relay_restrictions ，所以不需要再将其放在smtpd_recipient_restrictions 。
这是日志的讲述部分。 导致masegaloeh的答案。
