It would be nice if our customers could email our Jira service desk (and it then create a ticket and notify us like normal) without them having to go via the portal and filling out the fields.
I have tested sending an email to our jira SD externally via different mail clients and each time I get a bounce back email from bounce@atlassian.net saying "this message could not be delivered".
Has anybody achieved this at all? Or do external/new customers HAVE to go via the customer portal?
