How JIRA Updates Issues from Email

[anfield leung]

Hello,

I would like to know how does Jira (version 4.2.4) link up to existing issue with incoming email if the email subject didn't contain the issue key.

Found that: JIRA will inspect the header of the mail to find the "In-Reply-To" value, then attempts to link it to the message.

Does anyone can explain in detail how it works?

Thank you!!

Anybody can explain how it works exactly about the "In-Reply-To" part mentioned in the link below?

The JIRA mail handlers at all times require an issue-key in the subject in order for a comment to that issue to get added. If no issue-key is present, a new issue will get created (assuming a mail handler has been configured to create new issues as well).

Though I am not exactly certain, I believe the JIRA Enterprise Mail Handler might have additional funcitonality which could enable issue commenting where the issue-key is absent from the subject. I would expect the issue key requires to be present anywhere else in the mail in order for JEMH to be able to process it. JEHM however is a 3rd party plugin, please refer to their documentation and/or developer for more details on this.

Thank Mick. Knowing that JEMH might be able to help but we would not considering it at the moment for some reason.

I am asking this question because we found that even the issue-key is absent, most of the email is able to meger into the original issue as a comment , however, not 100%. So I would like to know exactly how's it works. Might not need a workaround at this stage, but I have to explain to user why it works sometime but sometime didn't.

There should be something related to "in-reply-to" helps to link up the issue
