I have a custom email integration. Over a year ago, I setup depuplication, so that replies to the original email would not create new incidents.
Open and resolve alerts based on custom rules: Trigger an alert if any of the following conditions apply The email subject matches the regular expression /.*/ Deduplicate based on the alert key found by matching the regular expression /(?:(?i)re: |fwd: )?(.*)/ against the email subject And create a generic alert for any email that does not match any of the above rules
This is no longer working.
