2 QQ邮箱
QQ邮箱默认的SMTP服务是关闭的,要自己去开通。
HOST:smtp.qq.com
try { SmtpClient client = new SmtpClient(); client.Host = "smtp.qq.com"; MailMessage mm = new MailMessage(); client.Port = 25; mm.From = new MailAddress("652105072@qq.com"); mm.To.Add(new MailAddress("1035092449@qq.com")); mm.Subject = "Hello~!"; mm.Body = "HIthere.here is a post "; mm.IsBodyHtml = false; mm.Priority = MailPriority.High; client.Credentials = new NetworkCredential("652105072@qq.com", "******"); client .Send (mm); } catch (Exception ex) { MessageBox.Show(ex.Message); }
