如何让SmtpClient通过http代理服务器发送邮件

HOST:smtp.163.com

public static string
CreateTimeoutTestMessage(string server)

{

string Success =
"发送成功";

try

{

string _to = "1035092449@qq.com";

string _from =
"young-20@163.com";

string _subject = "Using the new SMTP client.";

string _body =
@"Using this new feature, you can send an e-mail
message from an application very easily.";

MailMessage message = new
MailMessage();

message.From = new
MailAddress(_from);

//可以利用MailMessage.To.Add方法增加要发送的邮件地址

message .To .Add (new MailAddress ("652105072@qq.com"));

message.To.Add(new
MailAddress(_to));

message.Subject = _subject;

message.Body = _body;

//添加附件

Attachment a = new
Attachment(@"C:/Users/Administrator/Desktop/smtpclient.rar");

message.Attachments.Add(a);

//设置邮箱的地址或IP

SmtpClient client = new
SmtpClient(server);

//设置邮箱端口，pop3端口:110, smtp端口是:25

client.Port = 25;

//设置超时时间

client.Timeout = 9999;

//要输入邮箱用户名与密码

client.Credentials = new NetworkCredential("young-20@163.com", "******");

client.Send(message);

}

catch (Exception ex)

{

Success = ex.ToString();

}

return Success;
