dovecot - May 2010 - Dovecot and POP3

Hi all,

I run Dovecot 1.2.9, for both IMAP and POP3 access. I was wondering if 
there is a way to force messages be deleted from server when the user 
uses POP3, even if she  has selected a 'Leave messages on server' 
option. I was able to do it in the past using Qpopper 
(--enable-auto-delete option).

Thanks
