Increase Retry Time for SMTP on Exchange Mail Server

Can someone share how to increase the amount of time the SMTP server of Exchange 2003 takes to retry an email that has been rejected by a Greylisting email server to 1000 seconds?  I understand that by default, Exchange makes 3 attempts at 1 second intervals.  I received a message from a Greylisting server that requested a retry in 900 seconds.  I'm going to attempt to bump ours to 1000 seconds.

If you have a more practical solution that works, please share.

If you open up Exchange System Manager and expand Servers> Your Server> Protocols> SMTP> SMTP Virtual Server Properties> Delivery Tab
You will find the Retry interval for all outbound mail.  Make changes here and then restart the Simple Mail Transfer Protocol Service to kick the changes into effect.
