使用Gmail发送邮件心得

        public static bool SendEmail(string subject, string body, string to)
        {
            MailMessage myEmail = new MailMessage();
            Encoding eEncod = Encoding.GetEncoding("utf-8");
            myEmail.From = new System.Net.Mail.MailAddress(SmtpUserName, SmtpUserName, eEncod);
            myEmail.To.Add(to);
            myEmail.Subject = subject;
            myEmail.Body = body;
            myEmail.BodyEncoding = Encoding.UTF8;
            myEmail.Priority = System.Net.Mail.MailPriority.Normal;
            myEmail.IsBodyHtml = true;

            SmtpClient smtp = new SmtpClient(SmtpServer, 587);
            smtp.EnableSsl = true;
            string UserName = SmtpUserName;
            string Password = SmtpPassword;
            smtp.Credentials = new System.Net.NetworkCredential(UserName, Password);
            try
            {
                smtp.Send(myEmail);
                return true;
            }
            catch (Exception ex)
            {
                return false;
            }
            return true;
        }

注意：

使用gmail发送邮件写端口，可是当把端口设为465时，会报超时，因此只能设为587
