[exim] deny non-encrypted client connections (smarthost)

Hello,

I just set up exim for the first time. I got everything, but one last
thing, working the way I want it so far.

I would like to know if there is a way to deny non encrypted connections
when exim connects as a client to a smtp-relay/smarthost.

When acting as a smtp server I mananged to realize this through:

acl_check_mail:
deny !encrypted = *
message = TLS required

But, as I see it there are no access control lists (acl) for exim when
running as a client. Correct, or is this they way to do it?


Regards
Adrian
