When sending a message larger than 4096 bytes with smtpd on a ssl socket, everything hangs.

This is due to polling before synchronizing the SSL channel with the underlying socket.

The issue can be solved by properly modifying the poll function and handling the SSLWantRead exception.

I provide 2 (Debug)SMTPServer implementations and one client to show the error and the workaround all using ssl.

The workaround is not correct semantically but fixes the poll function behavior correctly.
