I'm in the process of migrating our environment from Exchange 2003 to 2010. For a while now, I have been receiving messages from postmaster@domain.com, most of which look like this:
To: Me
From: postmaster@domain.com
Subject: Blablabla
Content:
Delivery has failed to these recipients or groups:
userwhodoesn'texistanylonger@domain.com
The e-mail address you entered couldn't be found. Please check the recipient's e-mail address and try to resend the message. If the problem continues, please contact your helpdesk.

I received another message today that I believe was supposed to be quarantined (subject line was just [QUAR]) that was for another user entirely.
Why am I getting these?
