I made an error when I tried to change my RHEL 4 server an hour up for daylight savings time. Instead of the hour, I changed the year one up-> 2010. Before I realized the error, a number of emails went through the system. Now we have a group of emails that incorrectly appear to have been sent and received in 2010. Not only do the incorrectly represent the record, but they sit at the top of the email stack the user sees and cause confusion.

Is there any way to change these existing emails from 2010 to 2009?
