[X4U] Archiving Mail

[Rad Craig]

I use the Mail.app included in X.  I use it for an IMAP account for  
my business.  I have 2-300 individual folders, very organized, for  
vendor and customer relations as well as product development/ 
research.  As you can imagine, this is a HUGE mail file, well over  
1GB.  I don't delete anything.  I keep everything sent or received.

I do this so that I can go back to reference old emails from  
customers or vendors if needed.

Is there a way to archive some of these emails, say everything older  
than 6 months?  The only requirement is that I want to be able to  
search this archive if needed.  All of my IMAP mail is stored on the  
server, but I'd like to keep the archive on my local machine that the  
mail client runs on to conserve space on my web server.

Is there any way to do this?  If would be nice to save space and  
improve performance, only accessing the old stuff when needed.  I  
know I could do this with Outlook, but that was with a POP account, I  
just saved the old archives
