我在一台服务器上托管了 3 个域名，其中两个可以正常发送/接收电子邮件，但第三个域名由于某种原因拒绝电子邮件。
NOQUEUE: reject: RCPT from mail-lb0-f170.google.com[209.85.217.170]: 550 5.1.1 <[email protected]>: Recipient address rejected: User unknown in virtual mailbox table; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mail-lb0-f170.google.com>
奇怪的是，我的另外两个域名立即收到了电子邮件，并且所有三个域名都使用相同的 MX 记录（mail.mydomain.com），并且除了域名之外具有相同的 DNS 记录。
我已检查过是否可以从本地主机发送接收。这是 main.cf。我听说过禁用灰名单，但由于其他两个域发送/接收正常，我希望得到更好的解决方案。

哇，我真是个白痴！我的邮件数据库中有一个类型。
插入用户（电子邮件，密码）值（'[电子邮件保护]', ENCRYPT('密码'));
