That is not possible. The only retry specified in the SMTP protocol is a
fall-back from ESMTP to SMTP, when the EHLO is rejected and the client
retries with HELO instead. The server cannot force the client to use
ESMTP.

Exim cannot use tls_on_connect as a client. You have to use a stunnel or
something like that.
