From 9acb4a7c2a36f12a5ca71e5c4c74364d344e2c5f Mon Sep 17 00:00:00 2001 From: Micah Anderson Date: Thu, 3 Oct 2013 13:45:57 -0400 Subject: only use TLSv1 or later for smtp (Feature #4011) Disable on the client-side with postfix (smtp) SSLv2/SSLv3 and only allow for TLSv1 or later SMTP servers almost universally support TLSv1. There are very few servers that don't (the few that are would result sending in the clear for these, but the alternative isn't much better). This is unlikely to cause any significant problems.
