"A good general-purpose tool for maintaining local copies of your mail is OfflineIMAP. Here's my config file (with personal info censored) for backing up my gmail:

[general]
ui = Curses.Blinkenlights, TTY.TTYUI, Noninteractive.Basic, Noninteractive.Quiet
metadata = ~/.offlineimap
accounts = GMail
maxsyncaccounts = 1

[Account GMail]
localrepository = Gmail-local
remoterepository = Gmail-remote

[Repository Gmail-local]
type = Maildir
localfolders = ~/Mail/Gmail
sep = /

[Repository Gmail-remote]
type = Gmail
remoteuser = ********@gmail.com
remotepass = ********
holdconnectionopen = true
keepalive = 60
maxconnections = 1

Yes, unfortunately, you put your password in plaintext in the config file. There may be a better way, but I'm not paranoid enough to go looking for it."
