This is as far as i know a question which is sometimes asked but noone has an answer. (That is how I expirenced it...)
是的，我在 serverfault 上看到过这种问题，但从来没有以这种方式（postfixadmin）
我有 2 个域名（domain1.de 和 domain2.de）和 1 个邮件服务器（mailserver.domain1.de）。两个域名都设置了 SPF、PTR/ReverseDNS、DKIM、DMARC 记录。直到几天前，我只有一个域名（domain1.de），设置成功了。
现在我有了第二个，并且我使用 postfixAdmin 将其添加到 Postfix MTA。我收到以下错误，并决定使用 virtual_alias 发送任何要发送到的邮件[电子邮件保护]到[电子邮件保护]（这样，即使系统目前不太好，我也能收到重要的电子邮件）：
6月12日 17:34:06 441335-696 postfix/smtpd[18907]: NOQUEUE: 拒绝: 来自 xxxxxx-xxx.pph-server.de[91.134.xxx.xxx] 的 RCPT: 553 5.7.1 '[电子邮件保护]'：发件人地址被拒绝：不属于用户[电子邮件保护]; 来自='[电子邮件保护]‘ 至 = ‘[电子邮件保护]'proto=ESMTP helo='mails.domain1.de'
mails.domain1.de 是 Roundcube
现在再次回到我的设置：
在 /etc/postfix 中：
main.cf
master.cf
mysql-virtual-alias-maps.cf
mysql-vitrual-domains-maps.cf
mysql-vitrual-mailbox-maps.cf
