Ah, now I think I see.

  userdb static {
    args = uid=502 gid=502 home=/var/mail/vhosts/%d/%n
mail=mbox:/var/mail/vhosts/%d/%n/mail
  }

Am I correct in stating that the 'home' parameter will cause the indexes to
be placed in /var/mail/vhosts/%d/%n/.imap/INBOX (one for each user) and the
mail itself is in an mbox file named /var/mail/vhosts/%d/%n/mail?

The index conflict you describe also explains the problem I was
having with duplicate emails (mbox sync: UID inserted in the middle of
mailbox)
