Short method for creating and sending an email message using SMTP:

using System.Net.Mail;
....
private void SendSMTPMessage()
        {
            //declare a new message
            MailMessage message = new MailMessage();

            //Add Recipient to Message, can create multiple recipients if desired
            message.To.Add("user@mail.com");

            //message sent from
            message.From = new MailAddress("sender@mail.com");

            //message subject and body
            message.Subject = "Sample Message Subject";
            message.Body = "Sample message content";

//create the smtp client
SmtpClient smtp = new SmtpClient("my.smtp.server");

//I had to add this to get my message to send on Windows Server 2003 and IIS 6
smtp.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;

            //attempt to send message
            smtp.Send(message);
        }

Imports System.Net.Mail
...
Private Sub SendSMTPMessage()
'declare a new message
Dim message As New MailMessage

'Add Recipient to Message, can create multiple recipients if desired
message.To.Add("user@mail.com")

'message sent from
message.From = New MailAddress("sender@mail.com")

        'message subject and body
        message.Subject = "Sample Message Subject"
        message.Body = "Sample message content"

'create the smtp client
Dim smtp As New SmtpClient("my.smtp.server")

'I had to add this to get my message to send on Windows Server 2003
smtp.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis

'attempt to send message
smtp.Send(message)
End Sub
