JIRA Split Regex Mail Hander & Multiple Mail Clients

As a follow up to when I first played with this and my organisation was a Domino shop things have moved on.  Now an Outlook AND Domino shop, and the proliferation of mobile devices meant this simple regex wasn't working for heaps of mail clients.

Atlassian documentation is (currently) sparse on the subject, or maybe my lack of regex fu is the problem.  But found this answer on the 'Answers' site :

My new regex is :

/From: *|___.*|On .*wrote:|----Orig.*|On .*(JIRA).*/

But the power is now in my hands!
