Some mail servers tell me the envelope recipient in the Received header.
In this example the third headers shows needle@vooconto.de.

How can I configure the Microsoft SMTP Server to add "for needle@vooconto.de" to the received line?
Goal
I have a mailbox which receives mails for several addresses. I want to group the mails according their original (envelope) to-header.
