Mail is not processed as new request

Mail is not processed as new request

Hello everyone.

In search of a way to transfer a Request from one ESM Instance (HR) to another (IT), we tried to use a custom trigger with an email notification.
The letter is successfully sent on behalf of nrd@ and gets into the help@ box.
Then ESM Instance (IT) retrieves all emails from the help@ mailbox but does not create a new request.
I found this in the logs:

[07:29:24:795]|[11-05-2021]|[com.manageengine.servicedesk.mailutils.RequestMailHandler]|[INFO]|[18014]: This is a notification mail from the SDP application matched based on sdp-system-mail header.|

How do I get around this limitation?
