How to change Sender ID on Exchange 2007?
Posted on 2010-09-16
We recently changed our company name, and while we didn't yet change our domain, or migrate Exchange, our Exchange server is sending out emails from new email addresses associated with a new domain name.
Emails sent out from the server still have the server.olddomain.com stamp in the message ID field, which cause the emails to be dropped at the receiving end if they have Sender ID Filtering or other kind of SPF enabled.
How can I make Exchange stamp all emails with server.newdomain.com?
