HeaderRewriter allows an Exchange administrator to substitute any substring in the following SMTP headers of outgoing messages:
Current version: 126.96.36.199

The program also has been tested on Exchange 2010 SP1/SP2 on Windows Server 2008 Standard x64 Edition SP2 and on Exchange 2013 CU2 (a single server that plays Client Access and Mailbox roles).
