Some customers send the same email to multiple Jira email inboxes, and CC themselves.
The issues created have the same email id associated with them.
Customers then do a "reply to all" on the email they originally cc'd to themselves.
Because the create-or-comment handler looks at the in-reply-to internet header of the email, the comment gets attached appraently randomly to either of the issues. this is a problem when an old closed issue gets the new comments...
Is it possible to configure jira to ignore the in-reply-to header when deciding to create an issue or comment an existing issue?
I realise that this is essentially the customer's fault, but they are a large wholesaler in our industry, and getting them to change their processes may be difficult.
