I would configure this with MX records.

 

MX 10 mail.olddomain.com

Disable the virtual server for mail.newdomain.com until the migration.

 

Mailservers will first try MX 10 to send the email. If it is not responding they will send it to the next MX record in the list.

 

When you start the migration enable the virtual server for mail.newdomain.com and disable the virtual server for mail.olddomain.com

 

Sending mailservers will automatically start sending mail to mail.newdomain.com.

 

Cheers,
