这是一种情况

我发送的电子邮件的图像为html正文

I am sending an email that has image as html body

<img src="http://www.google.com/images/srpr/logo11w.png" alt="click me" />

收到电子邮件后，src更改为

After receiving email image src is changed to

<img src="https://bay179.mail.live.com/Handlers/ImageProxy.mvc?bicild=&amp;canary=ei12UmVJE9u9hgMk5TdV12Y1X%2b9Vc365IL%2bmULwd%2bfk%3d0&amp;url=http%3a%2f%2fwww.google.com%2fimages%2fsrpr%2flogo11w.pngf" alt="click me">

                sc.Credentials = new NetworkCredential("[e-mail]", "password");
                sc.EnableSsl = true;
                MailMessage m = new MailMessage();
                m.From = new MailAddress("[e-mail]");
                m.Subject = "test subject";
                m.IsBodyHtml = true;
                m.Body = "<img src=\"http://www.google.com/images/srpr/logo11w.png\" alt=\"click me\" />";
                m.To.Add(new MailAddress("[e-mail]"));
                sc.Send(m);

我不想嵌入图像。

推荐答案

正在接收端进行更改，并作为安全措施完成，以防止垃圾邮件发送者跟踪当他们的消息被打开时。电子邮件客户端通常会显示下载外部图像的选项。



如果您不想将图像嵌入电子邮件中，那么您无能为力防止这种情况。

That change is being made at the receiving end, and is done as a security measure to prevent spammers from tracking when their messages are opened. The email client will usually display an option to download external images.

If you don't want to embed the image in the email, then there is nothing you can do to prevent this.
