邮件发送问题！

[优途科技]

SmtpClient client = new SmtpClient("smtp.emapgo.com.cn", 25);//此处换成“smtp.163.com”就可以,这是为何？
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential("shizj", "*******");
client.DeliveryMethod = SmtpDeliveryMethod.Network;

MailMessage mail = new MailMessage("[e-mail]", "[e-mail]", "查看消息", "mail upon system.net.mail");
mail.IsBodyHtml = true;

try
{
client.Send(mail);
MessageBox.Show("发送成功！");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}


为何提示邮件没有发送？谢谢！
