Question

Send Email via C# through Google Apps account

Answer 1

+16 A:

There is no need to hard code all smtp settings in your code. Put them in web.config instead:

<configuration>
  <system.net>
    <mailSettings>
      <smtp from="[email protected]" deliveryMethod="Network">
          <network host="smtp.gmail.com" port="587"
              userName="[email protected]" password="password"/>
      </smtp>
    </mailSettings>
  </system.net>
</configuration>

End when you send email just enable SSL on your SmtpClient:

var message = new MailMessage("[email protected]");
// here is an important part:
message.From = new MailAddress("[email protected]", "Mailer");
// it's superfluous part here since from address is defined in .config file
// in my example. But since you don't use .config file, you will need it.

var client = new SmtpClient();
client.EnableSsl = true;
client.Send(message);

Make sure that you're sending email from the same email address with which you're trying to authenticate at Gmail.

Note: With .NET 4.0+ you can insert enableSsl="true" into web.config as well instead of hardcoding it

the full webconfig is under <configuration> and should be <system.net> <mailSettings> <smtp from="[email protected]" deliveryMethod="Network"> <network host="smtp.gmail.com" port="587" userName="[email protected]" password="password"/> </smtp> </mailSettings> </system.net>

@Rinat its new with .NET 4.0 just put enableSsl in <smtp>

Thanks. Added +1. Unfortunately 90% of production application are still .NET 3.5 and below. Esp. ones on the Azure.

Rinat Abdullin 2010-05-24 13:08:08

Azure now supports .Net 4.0 - This works great
