This is based on the exim4 package in Debian, if you have a receipe on how to do it using other exims, please tell me.
Add the three lines
hosts_require_tls = freerelay.err.no tls_certificate = /etc/exim4/freerelay.crt tls_privatekey = /etc/exim4/key.pem
/etc/exim4/conf.d/transport/30_exim4-config_remote_smtp_smarthost. Then, run
update-exim4.confand restart exim. Also, make sure you've set exim to use freerelay.err.no as your smarthost. Freerelay listens to port 25, 587 (submission), 6667 (irc) and 2525, so if any of those are blocked in your network, try another one.
