Migrating to GMail

[Nathan Ekstrom <nathan@xxxxxxxxxxx>]

Hello,

I currently maintain an email server for my extended family.  I'm 
considering switching to using Google email application for domains.  My 
biggest concern is migrating all of the email up to the Google servers.  
I've started experimenting with offlineimap for this and am wondering if 
any one has any pointers.  My local system uses Courrier as an imap 
server using maildir style mail directories.  What I am having trouble 
doing is pushing the mail up.  Thanks for any suggestions.
