今天凌晨1:53，我的Azure VM开始接收C：\ inetpub \ mailroot \ Queue中的意外的.EML文件。 早上6点左右，我第一次login，收到了36000多个文件。 作为解决方法，我停止了服务> SMTP。
我如何防止这种情况？
我正在开发一个将发送和接收SMTP的Web应用程序。 我刚刚开始使用SendGrid发送几天前，我只使用IIS接收到：C：\ inetpub \ mailroot \队列\
以下是.EML文件中的第一个和最后一个，作为示例……….
第一个.EML文件…………………………………

你没有得到“ .eml文件攻击”。 您收到大量发送给您的垃圾邮件，这非常自然，IIS将电子邮件存储在以.eml结尾的符合RFC822的文件中。
如果您想停止堆放.eml文件，则需要阻止垃圾邮件发送者。 要做到这一点，您需要执行大约九百万种不同方式中的任何一种来阻止和阻止垃圾邮件，其中许多方法在您仅使用IIS for SMTP时不可行。 考虑确定是否有共同的IP地址，垃圾邮件来自并阻止他们，或阻止似乎有问题的整个networking。 这可以通过Windows防火墙或位于IIS服务器前的防火墙完成。
更好的解决scheme是select一个具有更多function的SMTP服务器来阻止垃圾邮件。
