Answer 1

Your "from" user must be in the form of a valid email address.
message.From = new MailAddress(smtpuser);
Also, you will need to use the MailAddress constructor for the .To property as well.

Answer 2

Try, with port as 25 and IsSSLEnabled as true since gmail server is SSL enabled

Answer 3

Make sure the toMailAddress, and smtpuser are valid email address.
Try, Using smtpport = 587; provided by Gmail for Outgoing Mails (SMTP).
Hope this will make it work fine. Please list out the errors you encounter.

Answer 4

This code will work. What i have done are
proper smtphost
proper smtpport - 587
Enable SSL
set UseDefaultCredentials to false before setting the credentials
set DeliveryMethod
public static bool SendMail(string toMailAddress, string mailSubject, string mailMessage)
{
string smtphost = "smtp.gmail.com";
int smtpport = 587;
string smtpuser = "youremail#gmail.com";
string smtppwd = "password";
SmtpClient client = null;
string MessageBody = string.Empty;
try
{
var message = new MailMessage();
message.From = new MailAddress(smtpuser);
message.To.Add(toMailAddress);
message.BodyEncoding = System.Text.Encoding.UTF8;
message.Subject = mailSubject;
message.Body = mailMessage.ToString();
message.IsBodyHtml = true;
client = new SmtpClient();
client.Host = smtphost;
client.EnableSsl = true;
client.Port = smtpport;
client.UseDefaultCredentials = false;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.Credentials = new System.Net.NetworkCredential(smtpuser, smtppwd);
client.Send(message);
}
catch (Exception ex)
{
string x = ex.InnerException.Message;
Console.WriteLine(x);
}
return true;
}
