Question

我经常收到主题为“失败通知”的电子邮件，我在下面列举了一个例子。

我是否应该关注这个问题，如果我有任何可用的操作，那么看起来我的电子邮件地址被用作返回路径。

注意我已经将细节更改为“mydomain.co.uk”，这封电子邮件不是我的“removed_not_my_email@yahoo.com”，我的电子邮件是“my_email@mydomain.co.uk”

Hi. This is the qmail-send program at mydomain.co.uk.
I tried to deliver a bounce message to this address, but the bounce bounced!

This is a permanent error; I've given up. Sorry it didn't work out.

Answer 1

SMTP中的发件人没有验证。任何人都可以通过他们能想到的任何电子邮件发送电子邮件。

垃圾邮件＆amp;使用此事实分发恶意软件。绕过某些垃圾邮件过滤器，因为发件人地址/返回路径似乎是合法的。通知“内容”存在潜在的552-5.7.0安全问题＆＃39;可能意味着附加了可执行文件。也许是无害的，但可能是病毒或恶意软件。

不好，但你也无能为力。

为了避免将来使用您的电子邮件地址作为此做法的来源，请保护您的电子邮件地址。不要将它明确地发布在网页上。订阅网站和/或邮件列表时，请使用临时电子邮件地址。

许多电子邮件说＆＃34;失败通知＆＃34;
