* Added a work-around for GoDaddy's ASP.NET web host which does not support the iso-8859-1
 System.Text.Encoding (used as a fallback encoding within MailKit) by falling back to
 Windows-1252 instead.
* Improved NTLM support.
* Added support for the SMTP VRFY and EXPN commands.
* If the IMAP server sends a `* ID NIL` response, return null for ImapClient.Identify().
* Allow developers to override the charset used when authenticating. (issue #292)
