VDA patch TODO list
- remove the virtual_mailbox_limit_overrides and virtual_maildir_limit_message_maps 
  options. Both seems to be useless and obsolete
- remove the 
    virtual_trash_count 
    virtual_trash_name
  options, because they can lead to race conditions in quota
  counting when imap server does not count with this

2010-03-03
Changes in patch for 2.7.0:
- the maildirsize file is rewritten when 
  sum or count is less than 0 or
  sum is zero and count not or
  sum is not zero and count is zero
  - this all are nonsenses and it's necessary to rewrite the maildirsize
  when these results occur
- more accurate verbosity when verbosity is on, function name in each message
  should be printed
- check_dir_size(): condition for skipping ".." and "." changed and also
  the condition for counting/skipping .Trash folder (depends on var_virtual_trash_count)
- bugfix: the full scan is not run when quota is 0. This cause also maildirsize
  to be rewritten and that's not maildir++ compliant
