[fetchmail] Fetchmail Cyrus question

Hello,
    I am trying to use fetchmail to deliver to mailboxes created with cyrus.
The mailbox users are not users on the OS.  Reading the Fetchmail FAQ answer
C1, it would seem to be saying that if the user does not exist on the
underlying OS, mail for that user will be delivered to the uid running
fetchmail.  Thus it would seem that fetchmail is not a mail retrieval
utility that works well with Cyrus.  Is this correct?
TIA
Al
