title: What ports does a 'System.Net.Mail.SmtpClient' need with 'SmtpClient.EnableSsl' set to true?
body: <p>As the title says, what ports does an 'System::Net::Mail::SmtpClient' need with 'SmtpClient::EnableSsl' set to true?</p>
  
  <p>The <a href="http://msdn.microsoft.com/en-us/library/system.net.mail.smtpclient.enablessl%28v=vs.110%29.aspx" rel="nofollow">documentation on the <code>EnableSsl</code> property</a> says the default port for an alternative connection method is 465 but doesn't mention what's used for the connection type it <em>does</em> support.</p>
  
  <p><strong>Edit</strong> - If it makes a difference, I'm connecting to Gmail in this instance but generic answers would be welcome.</p>
