Send a Simple Email

Create a simple email and sends it. The SendEmail method establishes a connection (session) with the SMTP server if necessary, and leaves the connection open so that additional sends may proceed using the same session. The SMTP connection (session) may be explicitly closed by calling CloseSmtpSession.

Important: Some SMTP servers do not actually send the email until the connection is closed. In these cases, it is necessary to call CloseSmtpConnection for the mail to be sent. Most SMTP servers send the email immediately, and it is not required to close the connection.
