php - mail() 错误地向 cPanel 默认帐户发送电子邮件

Question

我从 GoDaddy 购买了一个域并将其链接到 Office 365（通过 MX 记录）。这意味着我在 Outlook 中有几个电子邮件帐户是 @mydomain.com。

示例 Outlook 帐户：

• [e-mail]
• 联系人@mydomain.com
• [e-mail]

我可以通过这些帐户发送/接收电子邮件。

---

我的网站托管在安装了 cPanel 的基本虚拟主机上，这意味着我获得了一个“默认”电子邮件帐户。例如：[e-mail]。我在我的网站（联系表格）上编写了一个 PHP 脚本，通过mail()to发送电子邮件[e-mail]。

但是，所有电子邮件都发送到默认 cPanel 帐户[e-mail]而不是 Outlook 帐户[e-mail]。

为了测试，我尝试将电子邮件发送到我的个人帐户，该帐户未托管在 mydomain 上，并且它按预期工作。电子邮件会立即发送。

为什么我的网站会错误地将电子邮件发送到 Outlook 帐户？谢谢你的时间。

解决方案是将我的 cPanel“电子邮件路由”选项更改为“远程”，以便所有本地电子邮件首先检查 MX 记录。
