Exim now has Experimental "Proxy Protocol" support. It was built on
specifications from:
http://haproxy.1wt.eu/download/1.5/doc/proxy-protocol.txt
+Above URL revised May 2014 to change version 2 spec:
+http://git.1wt.eu/web?p=haproxy.git;a=commitdiff;h=afb768340c9d7e50d8e
The purpose of this function is so that an application load balancer,
such as HAProxy, can sit in front of several Exim servers and Exim
+Certificate name checking
+--------------------------------------------------------------
+The X509 certificates used for TLS are supposed be verified
+that they are owned by the expected host. The coding of TLS
+support to date has not made these checks.
+
+If built with EXPERIMENTAL_CERTNAMES defined, code is
+included to do so, and a new smtp transport option
+"tls_verify_cert_hostname" supported which takes a list of
+names for which the checks must be made. The host must
+also be in "tls_verify_hosts".
+
+Both Subject and Subject-Alternate-Name certificate fields
+are supported, as are wildcard certificates (limited to
+a single wildcard being the initial component of a 3-or-more
+component FQDN).
