发送邮件的服务端代码为:
SmtpClient 发送邮件的对象 //代码省略
System.Net.Mail.MailMessage mailMessage = new System.Net.Mail.MailMessage();
mailMessage.From="发送者邮箱";
mailMessage.To.Add("收件人邮件列表");
mailMessage.CC.Add("抄送人邮件列表");
mailMessage.Subject = subject;
AlternateView htmlBody = AlternateView.CreateAlternateViewFromString(content,null,"text/html");
LinkedResource lrImage = new LinkedResource("a.jpg","image/gif");
lrImage.ContentId = "Email001";
htmlBody.LinkedResources.Add(lrImage);
mailMessage.AlternateViews.Add(htmlBody);
SmtpClient.Send(mailMessage);

////HTML格式邮件的内容
string htmlBodyContent = "如果你的看到<b>这个</b>, 说明你是在以 <span style=\"color:red\">HTML</span> 格式查看邮件<br><br>";

htmlBody.LinkedResources.Add(lrImage);
mm.AlternateViews.Add(htmlBody);
////要求回执的标志
mm.Headers.Add("Disposition-Notification-To", "abc@163.com");
////自定义邮件头

////针对 LOTUS DOMINO SERVER,插入回执头
mm.Headers.Add("ReturnReceipt", "1");

////如果发送失败,SMTP 服务器将发送 失败邮件告诉我
mm.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;
////异步发送完成时的处理事件
smtp.SendCompleted += new SendCompletedEventHandler(smtp_SendCompleted);
////开始异步发送
smtp.SendAsync(mm, null);
