以下代码能发送成功，你对比下与你的代码看有什么不同的地方吧
------------------------------------------------
using System.Net.Mail;

static string strHost = string.Empty;
static string strAccount = string.Empty;
static string strPwd = string.Empty;
static string strFrom = string.Empty;

protected void Page_Load(object sender, EventArgs e)
{

}

protected void Button1_Click(object sender, EventArgs e)
{
strHost = "smtp.163.com"; //STMP服务器地址
strAccount = "你的登录用户名"; //SMTP服务帐号
strPwd = "你的登录密码"; //SMTP服务密码
strFrom = "[e-mail]"; //发送方邮件地址

Response.Write(sendMail("[e-mail]", "这是一封测试邮件", "这是一封测试邮件的正文内容") ? "Success" : "Unsuccess");

// Console.ReadLine();
}



protected bool sendMail(string to, string title, string content)
{
SmtpClient _smtpClient = new SmtpClient();
_smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;//指定电子邮件发送方式
_smtpClient.Host = strHost; ;//指定SMTP服务器
_smtpClient.Credentials = new System.Net.NetworkCredential(strAccount, strPwd);//用户名和密码

MailMessage _mailMessage = new MailMessage(strFrom, to);
_mailMessage.Subject = title;//主题
_mailMessage.Body = content;//内容
_mailMessage.BodyEncoding = System.Text.Encoding.UTF8;//正文编码
_mailMessage.IsBodyHtml = true;//设置为HTML格式
_mailMessage.Priority = MailPriority.High;//优先级

//发送附件
if (FileUpload1.HasFile)
{
Attachment atfiles = new Attachment(FileUpload1.PostedFile.FileName);
_mailMessage.Attachments.Add(atfiles);
}

try
{
_smtpClient.Send(_mailMessage);
return true;
}
catch
{
return false;
}
}

把你的用户名:string username = "[e-mail]";
改成:string username = "jiangtianyin";
试下
