From 5ce9e19ef0744f530a797c30a82e9723eb7ea306 Mon Sep 17 00:00:00 2001 From: Edwin Mons <edwin.mons@isode.com> Date: Wed, 24 Oct 2018 22:40:51 +0200 Subject: Strip off trailing dot from domainpart of jid RFC 6122 specifies that if a domainpart ends in a dot, it must be stripped off before any other canonicalisation steps are taken. Unit tests have been added to check that various JID scenarios with a domain ending in a dot pass or are rejected as expected. Test-Information: Unit tests pass on macOS 10.13. Manual tests in sluift show expected behaviour.
