Sending Email in .NET Through Gmail

Question

Instead of relying on my host to send email, I was thinking of sending the messages though my gmail account. The emails are personalized emails to the bands I play on my show. Has anyone had success doing this?

Answer 1

http://www.systemwebmail.com/ is probably the most absurdly complete site dedicated to a single .NET namespace...but it has EVERYTHING you could ever want to know about sending mail via .NET, be it ASP.NET or Desktop.

Answer 2

Be sure to use System.Net.Mail, not the deprecated System.Web.Mail. Doing SSL with System.Web.Mail is a gross mess of hacky extensions.

using System.Net.Mail;

var fromAddress = new MailAddress("[email protected]", "From Name");
var toAddress = new MailAddress("[email protected]", "To Name");
const string fromPassword = "fromPassword";
const string subject = "Subject";
const string body = "Body";

var smtp = new SmtpClient
           {
               Host = "smtp.gmail.com",
               Port = 587,
               EnableSsl = true,
               DeliveryMethod = SmtpDeliveryMethod.Network,
               UseDefaultCredentials = false,
               Credentials = new NetworkCredential(fromAddress.Address, fromPassword)
           };
using (var message = new MailMessage(fromAddress, toAddress)
                     {
                         Subject = subject,
                         Body = body
                     })
{
    smtp.Send(message);
}

Answer 3

The above answer doesn't work. You have to set "DeliveryMethod = SmtpDeliveryMethod.Network" or it will come back with a "client was not authenticated" error. Also it's always a good idea to put a timeout.

Revised code:

using System.Net.Mail;
using System.Net;

            var fromAddress = new MailAddress("[email protected]", "From Name");
            var toAddress = new MailAddress("[email protected]", "To Name");
            const string fromPassword = "password";
            const string subject = "test";
            const string body = "Hey now!!";

            var smtp = new SmtpClient
            {
                Host = "smtp.gmail.com",
                Port = 587,
                EnableSsl = true,
                DeliveryMethod = SmtpDeliveryMethod.Network,
                Credentials = new NetworkCredential(fromAddress.Address, fromPassword),
                Timeout = 20000
            };
            using (var message = new MailMessage(fromAddress, toAddress)
            {
                Subject = subject,
                Body = body
            })
            {
                smtp.Send(message);
            }

SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");

mail.From = new MailAddress("[email protected]");
mail.To.Add("[email protected]");
mail.Subject = "Test Mail";
mail.Body = "This is for testing SMTP mail from GMAIL";

SmtpServer.Port = 587;
SmtpServer.Credentials = new System.Net.NetworkCredential("username", "password");
SmtpServer.EnableSsl = true;
