title: How can I connect to a mail server using SMTP over SSL using Python?
body: <p>So I have been having a hard time sending email from my school's email address. It is SSL and I could only find this code online by Matt Butcher that works with SSL:</p>
  
  <pre><code>import smtplib, socket
  
  __version__ = "1.00"
  
  __all__ = ['SMTPSSLException', 'SMTP_SSL']
  
  SSMTP_PORT = 465
  
  class SMTPSSLException(smtplib.SMTPException):
      """Base class for exceptions resulting from SSL negotiation."""
  
  class SMTP_SSL (smtplib.SMTP):
      """This class provides SSL access to an SMTP server.
      SMTP over SSL typical listens on port 465. Unlike StartTLS, SMTP over SSL
      makes an SSL connection before doing a helo/ehlo. All transactions, then,
      are done over an encrypted channel.
  
      This class is a simple subclass of the smtplib.SMTP class that comes with
      Python. It overrides the connect() method to use an SSL socket, and it
      overrides the starttles() function to throw an error (you can't do 
      starttls within an SSL session).

          will connect. If specified, `port' specifies the port (on `host') to
          which this object will connect. `local_hostname' is the name of the
          localhost. By default, the value of socket.getfqdn() is used.
  
          An SMTPConnectError is raised if the SMTP host does not respond 
          correctly.
  
          An SMTPSSLError is raised if SSL negotiation fails.

          If the host name ends with a colon (`:') followed by a number, 
          that suffix will be stripped off and the
          number interpreted as the port number to use. This will override the 
          `port' parameter.

          specified during instantiation.
