问题

我一直在 virtualbox 中配置虚拟邮箱进行测试，但它似乎接受所有用户，甚至是未在 virtual_mailbox_maps 中定义的用户，尽管清除了 mydestination（因此它不会被处理为本地邮件）并添加了一些 smtpd_recipient_restrictions

当我测试将邮件发送到不存在的邮箱（但退出域）时，例如

echo "This is the body of the email" | mail -s "This is the subject line" [email protected]

/var/log/maillog 显示

postfix/qmgr[14474]: E890D1883308: from=<[email protected]>, size=470, nrcpt=1 (queue active)
E890D1883308: to=<[email protected]>, relay=myhook, delay=0.6, delays=0.03/0.01/0/0.56, dsn=2.0.0, status=sent (delivered via myhook service)

这意味着它被接受并被发送到虚拟传输而没有被拒绝。

希望能得到一些帮助

问题在于此配置行

smtpd_recipient_restrictions = reject_unknown_recipient_domain reject_unauth_destination reject_unverified_recipient

您必须检查限制中的收件人地址。查看 check_recipient_access 配置参数：

smtpd_recipient_restrictions = 
    reject_unknown_recipient_domain,
    reject_unauth_destination,
    reject_unverified_recipient,
    check_recipient_access mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf
