I've updated dovecot to v2.2.27, and configured POP3 this way, without
other changes on IMAP or LDA:

protocol pop3 {
  # Space separated list of plugins to load (default is global mail_plugins).
  mail_plugins = $mail_plugins last_login virtual

  # Virtual POP3 INBOX
  # The default namespace that is visible to IMAP clients
  namespace inbox {
    inbox = no
    prefix =
    separator = /
    list = yes
  }
  # Virtual namespace for the virtual INBOX. Use a global directory for dovecot-virtual files.
  namespace virtual {
    inbox = yes
    prefix = virtual/
    separator = /
    #location = virtual:/etc/dovecot/virtual:INDEX=~/Maildir/virtual
    location = virtual:/etc/dovecot/virtual:INDEX=MEMORY
    list = no
    hidden = yes
  }
  # Copy of the inbox namespace. We'll use this in dovecot-virtual file.
  namespace real {
    prefix = RealMails/
    separator = /
    list = no
    hidden = yes
  }

}

With /etc/dovecot/virtual/INBOX/dovecot-virtual containing:

RealMails/INBOX
RealMails/BOX1
RealMails/BOX2
  all

Thanks to cmouse on #dovecot who helped me to get the right config.

There is at least one problem left, if there is some subdirectory created
inside INBOX, dovecot will stop to list you emails inside INBOX folder while
POP3'ing. They remain visible when IMAP'ing. The only way to get back INBOX
emails for POP3 users is to remove the virtual POP3 config...

Or I am missing something here http://wiki.dovecot.org/Plugins/Virtual or there
is a bug in the virtual plugin.
