I want to use exim4 as a smarthost to send email using an smtp mail account over ssl. I've seen the hosts_require_tls option, but I need SSL and not TLS. How should I do this?
You can set the
protocol option in your smtp transport to
smtps. This will cause Exim to connect out on port 465, and initiate TLS as soon as it connects to the remote server.
See the documentation for
protocol at http://www.exim.org/exim-html-current/doc/html/spec_html/ch-the_smtp_transport.html for more information.
