In some SMTP server implementations (i.e. Postfix) you can enable Delivered-To and X-Original-To headers that will be added to your email. (or [X-]Envelope-To)

This is very helpful with distribution lists to determine which e-mail address the mail has been redirected to.

So, when the mail has been sent to [email protected], you can see in the Delivered-To or Envelope-To header that it has been redirected (distributed) to [email protected], which is one of many other e-mail addresses that are linked to a single mailbox.

How do I find which address was used to deliver this mail to a specific mailbox on Microsoft Exchange 2010?

Looking at the plain message (with all headers) i can not find any information that the mail arrived via address [email protected]

I think I need the Delivered-To header (or a similar one) to be set on Microsoft Exchange when a mail is delivered via distribution lists.

Is there any way to enable such header in Exchange 2010?

I need it so that our Ticket system (OTRS) correctly recognizes where the ticket belongs to. Adding all the e-mail addresses of all distribution lists to the system configuration is not the right solution.

And if there is a solution for Exchange 2010, is this possibly also applicable to Exchange 2007?
