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 
  options, because they can lead to race conditions in quota
  counting when imap server does not count with this

VDA patch ChangeLog
2016-09-30 [Tomas Macek]
- added 2.11.0 - 2.11.7, all in v13
- added 3.0.0 - 3.0.3 (thanks to Cristian Sava), all in new v14 (there were a few hunks 
  and fails when trying to apply the v13 patch to 3.0.x source tree)

2016-03-23 [Tomas Macek]
- added rest patches for currently available 2.10.x Postfix versions.
  They're all v13. Original v13 patch had to be changed because of one Hunk

2014-10-08 [Tomas Macek]
- 2.9.0 - 2.9.9 support, v12
  This new version applies the "read_mds" patch of Toshiya Seyama and compiling 
  patch for Debian made by Ervin Hegedus.
  The "read_mds" patch just redefines the read_mds variable and changes it's type
  from "int" to "long". This bug forced the virtual agent to recount the quota if
  it delivered any email into maildir with quota over 2 GB.

  The patch for proper compiling in Debian is just code cleanup for better 
  code compability with Debian.

2013-06-07 [Tomas Macek]
- 2.10.0 support, v13
  The new version v13 means, that I had to make some little changes in mailbox.c, 
  because the compiler complained about some declarations and uses of the Postfix's 
  - #include  for missing set_file_limit function prototype
  - removed line with "long end" declaration
  - removed line with "end = vstream_seek()" and replaced by just "vstream_seek()",
    because the "end" was never used

  All these changes should have no affect to the patch behaviour and functionality.

2013-05-07 [Tomas Macek]

2012-04-10 [Tomas Macek]

  some minor code changes were done (%ld -> %li etc.)

- 2.8.6, 2.8.7, 2.8.8 support with no changes
- 2.7.7 and 2.7.8 support with no changes

2011-03-03 [Tomas Macek]
- 2.8.1 support
- new versioning! New versions of patch will have it's serial number in the file name. 
  I'm just beginning with "v10"
- better verbose output in v10
- README_VDA shortened, I don't want to keep the thing on 2 places, only reference to 
  our official pages vda.sf.net remained

2011-02-16 [Tomas Macek]
- no change, only 2.7.2 and 2.8.0 support, 1 Hunk succeeded only when applying patch 2.7.1
  to the both tree of sources

- 2.7.1 support

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

- change Log created
- changed name from postfix-2.6.*-vda-ng-64bit  to postfix-2.6.*-vda-ng-bigquota
