If you configure a 'proxyservers' account, you will be be able to assume
the identities of your users without having their passwords. See the
imapsync manpage for how to make use of it (--authuser1, --authuser2). 

Mutt would be a more flexible option since it would allow you to select
date ranges, at the expense of being more labor intensive.
