public static bool Send(string MessageFrom, string MessageTo, string MessageSubject, string MessageBody)

MailMessage message = new MailMessage();
if (FileUpload1.PostedFile.FileName != "")

Attachment att = new Attachment("d://test.txt");//发送附件的内容
message.Attachments.Add(att);

message.From = new MailAddress(MessageFrom);
message.To.Add(MessageTo); //收件人邮箱地址可以是多个以实现群发
message.Subject = MessageSubject;
message.Body = MessageBody;
//message.Attachments.Add(objMailAttachment);
message.IsBodyHtml = true; //是否为html格式
message.Priority = MailPriority.High; //发送邮件的优先等级
SmtpClient sc = new SmtpClient();
sc.Host = "smtp.sina.cn"; //指定发送邮件的服务器地址或IP
sc.Port = 25; //指定发送邮件端口
sc.Credentials = new System.Net.NetworkCredential("****@sina.cn", "****"); //指定登录服务器的用户名和密码(发件人的邮箱登陆密码)
try
{
sc.Send(message); //发送邮件
}
catch
{
return false;
}
return true;
}
调用：
string ss="http://baidu.com";
if (Send("kgfis@sina.cn", i.Trim(), "群发测试" + DateTime.Now.Second.ToString(),ss))
{
rep = "发送成功！";
}
else
{
rep = "发送失败";
}
问题如题，症状是返回true，但目标邮箱没能收到邮件。最后用system.web.mail解决问题，想知道为什么 system.net.mail不能发送在正文中带有英文的冒号的邮件，还是我的代码有问题？希望各位高手能帮忙解答一下，谢谢。
下面是 system.net.mail 的代码：
public static bool Send(string from,string to,string subject,string body)
{
try
{
string username="***@sina.cn";
string password="********";
MailMessage mailMsg = new MailMessage();
mailMsg.BodyFormat = MailFormat.Html;
mailMsg.To = to;
mailMsg.From = from;
mailMsg.Subject = subject;
mailMsg.Body = body;
mailMsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1");
mailMsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername",username);
mailMsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword",password);
SmtpMail.SmtpServer = "smtp.sina.cn";//smpt服务器
SmtpMail.Send(mailMsg);
}
catch
{
return false;
}
return true;
}
