Summary
When using a Jira Mail Handler to create new issues, user replies to that mail will add unnecessary email history to the newly created issue. When a user replies to an existing issue, long email history and trails get added to the issue as well.
Environment
Jira Software 9.12.X, 10.3.X
Reproduction steps
Create an Incoming mail server and mail handler
Send an email to create an issue
When the user replies to the confirmation message/acknowledgement, the entire email history is added to the Jira issue
Solution
If the reply email has a body similar to the following:
FROM:
TO:
Sent:
Subject:We can remove this unnecessary information with a Regular Expression (also called RegEx). Use the RegEx below, and add it to the incoming mail handler for the option "Split regex."
/(\r?\n|\r)From:.*(\r?\n|\r)Sent:.*(\r?\n|\r)To:.*(\r?\n|\r)Subject:.*/iComments are added as expected, filtering out the email trail.
