For incoming, use an "encrypted = *" ACL condition.
For outgoing, use a "hosts_require_tls = *" option on all relevant smtp
transports.
If you're interested in observing peer certificates, look into Exim's
Events extension and the certificate-related string expansions. You'll
be amazed how many certs presented are non-verifiable. IMHO, after
just getting people to make encryption available, cert verifiability
will be the next Big Problem.
