to each email sent to the RT, a ticket is created. In this way, an automatic email is sent to requester. It turns out that is being generated two tickets and two automatic emails. I.e:
Are you using something like fetchmail to get the email into the RT server? If so, it might be that mail isn’t being marked as read/deleted after RT gets hold of it, so its being presented again.
I’m using postfix to get the email into the RT server. I.e: I actually send an email to abuse@outlook.com and is redirected to rt@rt.postfix.com is an alias of exchange to postfix

Not quite sure what your yellow highlighting is supposed to be showing there - those highlighted lines are from different mail system transactions.
If you looks at the tickets in RT, are the message IDs (look in “Show full headers” on the ticket display) the same for all the duplicated tickets, or different? If they’re different, its not RT duplicating the emails, but something in your mail system. You can also match the message IDs in RT with the IDs you can see in the postfix logs.
