On freebsd 8.0: standard install from ports collection:
1) virtual_gid_maps problems
#GID does not appear to be working
virtual_gid_maps = mysql:$config_directory/mysql_gids.cf
#virtual_gid_maps = static:2001
Postfix creates new directories/mail with gid of postfix user only,
completely ignoring virtual_gid_maps. I have tested both static and mysql
configurations, same result.
2) Postfix is not changing to root then chown'ing directories to
appropriate virtual_uid_maps. Please see proftpd code as how they
accomplish this. Problem is when you add a new "maildir" to mysql table
that has not existed before, postfix will change euid to the uid of
virtual_uid_maps, then attempt to create directories, which forces sys
admin to make the virtual_base directory mode 777 as it constantly needs
to create directories with new UIDs within there, so just doing a euid
change to uid of virtual_uid_maps is not enough to do the initial create
of first directory.
Obviously a solution to this is for enduser to create the first directory
ahead of time, but this should really be done server side.
