TLS_ON_CONNECT is unnecessary.

However, be aware that a mail server might expect the envelope From to
correspond to the mail account name, otherwise the mail will not be
authorised. Gmail doesn't do this but others do. By default, Exim will
use the login name on the machine plus the content of /etc/mailname for
the From address.
