[Dovecot] dovecot lda with fetchmail

hi all,

I'm new in dovecot, and i need to setup a machine that download emails from an external pop3 server, and delivers to my internal network via imap, for this , i want ( if possible ) to use fetchmail with the option mda to dovecot's deliver, because all user must be virtual users stored in a sqlite database, and my question is:

1- it is possible?? 2- theres a better way to do this?? 3- someone knows some howto about this configuration???

thanks for all
