我从一家德国托管商那里租用了自己的域名，并在其上创建了 4 个电子邮件帐户。5 年多来一切都很顺利。
大约一周以来，其中一个账户每天会收到大约 5 封来自“邮件投递系统”（[email protected]）的电子邮件，主题为“未送达的邮件已退回给发件人”，内容如下（我希望我已经用 XXX 审查了所有个人部分）：

No action is required on your part. Delivery attempts will continue for
some time, and this warning may be repeated at intervals if the message
remains undelivered. Eventually the mail delivery software will give up,
and when that happens, the message will be returned to you.

- 我能做些什么吗？也就是说，有人使用我的真实账户登录来发送消息吗？
- 或者有人使用他自己的邮件服务器，并只填写我的地址作为发件人？（在这种情况下，我怀疑我无能为力）
我已经更改了此帐户的密码，但消息仍继续出现。
