dovecot - Oct 2008 - Keep the email on the server

Hello,

I migrate my server POP3/IMAP recently the Courier-IMAP for Dovecot and 
am having
problems when the user configures your e-mail client to leave a copy of 
mail on the server.

All mail in the inbox, are brought all the time that you check your mailbox
input via POP3, causing a large traffic of unnecessary data every time. 
In my opinion
you should bring only the new mail, unread.

Can you tell me if this is a configuration issue on Dovecot?

Thank you all

Only if you provide enough information... do you think we are mind
readers? ;)

For starters, what version of dovecot? What is output of dovecot -n?

The same mails are downloaded over and over again? I'm guessing using
Outlook as the client? What do you have in pop3_uidl_format? Your
dovecot -n output didn't provide it, which means you're using a
distribution package that set a default for it. Perhaps a bad default.
See http://wiki.dovecot.org/POP3Server -> UIDL format.
