This is a pretty good deal: 50% off new licenses of Trend's ScanMail suite if you're migrating from Exchange 5.5 to Exchange 2003. You have to have more than 1,000 seats, and you have to have proof of migration (evidenced by a current SA license or Exchange 2003 CALs purchased after 6/15/04), and the offer is only good until 12/31/04.
