[fetchmail-users] Accessing user mailbox from another account

[Ian M. <ia...@in...>]

I have been charged with migrating an exchange 2000 instalation to a
linux server and am using fetchmail to handle interopability during the
migration period.
 
I am currently re-delivering email that arrives on the linux box to
MSExchange via smtp and its working like a dream.
 
I now need to be able to pull new email from the exchange server and
deliver it to the linux server. To avoid the need to know the users
passwords I want to give read/write access rights to their mailboxes to
a special account and to read all the mailboxes using a single
priviliged account.
 
Now, my problem, what is this type of access called ? I've been looking
at the fetchmail documentation for pop3 and imap access and am lost in
the sea of authentication types and options, though it seems pretty
likely that it is possible.
 
Can anyone steer me in the right direction ? 
 
regards
