I have dovecot (with squirrel mail etc.) running without any problems but cannot understand how to get e-mail from a pop server into dovecot. I have fetchmail configured to pick up the mail from the pop3 server but don't understand how to get it from there into my dovecot mbox
configure dovecot-deliver as MDA for fetchmail. If you use system users, calling "deliver" should be sufficient.On virtual users, you probably need to pass the correct recipient to deliver.
