[Exim] Why is exim trying to use TLS?

I've just notice a message in my queue doing the followin:

T: remote_smtp for geovannyl@???

192.188.53.8

I don't know why is trying to start a TLS connection with this remote
host. I haven't configured anything to use TLS checked the config file
and couldn't find anything related to TLS or STARTTLS.

Is this a problem with my instalation or is the remote server that
should not advertise STARTTSL?

Thanks
