Anyone else having issues with this in Gutsy?
I just downloaded and recompiled postfix to make sure there were no errors and I don't see any:
patch -p1 < ../postfix-2.4.5-vda-ng.patch
patching file README_FILES/VDA_README
patching file src/global/mail_params.h
patching file src/util/file_limit.c
patching file src/virtual/mailbox.c
patching file src/virtual/maildir.c
patching file src/virtual/virtual.c
patching file src/virtual/virtual.h
No errors after dpkg-buildpackage
Installed packages and restarted postfix sent an e-mail to a user but there is still no maildirsize file in the users Maildir....
