As of now there is no direct support to the SMPT /POP3 but you can send or recive the mails using the Microsoft MAPI support or else going for the direct Socket Programming is the only answer, for that you reffer the RFC 1939, RFC-822,RFC-1081.

POP3{

* APOP name digest     Authenticate by sending message digest (MD5) of UTC date-time
                       string passed by server at TCP connection and  user's password.

* USER name            Send the user's mailbox name to server.

* PASS password        Send the user's password as clear text.
 
Transaction Phase
  DELE msg             Tell the server to delete a particular message.

  LIST [msg]           Tell the server to send a list of mail messages and length of each
                       mail message in bytes (one message per line).

  NOOP                 No operation.

  RETR msg             Request to retrieve a particular message from the server.

  RSET                 Reset state and unmask any messages marked for deletion.

  STAT                 Tell the server to send several messages and their sizes in bytes.

* TOP msg lines        Tell the server to send a message header, a blank line, then several
                       lines from the message.

* UIDL [msg]           Tell the server to send a unique-ID listing for all messages or an individual
                       message. The server sends a message number followed by an  arbitrary string (usually a hash of the message header and text).
 
Update Phase
  QUIT                 Tell the server to commit changes to the maildrop.
 
At least this much commands should be created for a good POP3 client.
}
