[exim] TLS configuration

(Ubuntu 12.0.4 - Exim4 -Baruwa 2.0.0)

I'm doing the final configuration of an inbound relay server (not used
for sending). The exim4.conf file I am using utilizes TLS. I created a
.key and .pem file and a telnet session verifies the server is ready for
TLS connections.

I'm getting a lot of the following in my logs, but don't know if it is
normal, or an issue with my configuration, understanding it will err out
if the sender is not using TLS. I'm not really sure there is a need for
TLS, since all the servers I relay to are trusted. Any advice is
appreciated.
