Can Dovecot replace fetchmail?

[Kenneth Porter]

I'm using fetchmail to grab mail for multiple accounts from an external 
IMAP server and drop it into local mailboxes via SMTP. It polls the remote 
server every two minutes. Can Dovecot replace this functionality more 
elegantly, using IDLE to avoid the polling necessary with fetchmail? I'd 
like to designate that mail for specific accounts on the external server be 
moved to specific local mailboxes.
