Support non-ascii characters in email addresses (JEMH-6431)

JIRA server (7.8 - 7.9) ship with the core javamail library v 1.5.6, as/when they upgrade libraries to 1.6.0 JIRA (and therefore JEMH) can support accented email addresses such as:

andré@localhost

Update 14th May 2018

Atlassian have upgraded the Javamail library that will be shipping with the next releases of Jira, see JRASERVER-67175 for relevant fix versions. Non-ascii email addresses will be supported by JEMH if you are running a version of Jira that contains the updated Javamail version.

Current Jira releases do not allow (a) creation of users with non-ascii email address (b) processing of inbound mail with non-ascii email addresses (c) sending of outbound mail with non-ascii email addresses.

Upgrading the platform libraries has been shown to work locally. JEMH need some code changes to support this, which will feed into the JIRA 7.8+ compatible release.

We believe everything will work as expected, the configuration is still undergoing testing - until Alassian officially supports this, customers upgrading javamail do so at their own risk.
