Jeremy, cPanel recommends an upgrade from TLS 1.1 connections to TLS 1.2 connections.
See, " [23:12:57 35-236-118-198 root@95097357 ~]cPs# grep -i openssl_options /etc/exim.conf* /etc/exim.conf:openssl_options = +no_sslv2 +no_sslv3 +no_tlsv1 +no_tlsv1_1 /etc/exim.conf.localopts:openssl_options=+no_sslv2 +no_sslv3 +no_tlsv1 +no_tlsv1_1." How do I complete such an Exim upgrade?
