Why do virtual_uid_maps and virtual_gid_maps require a numeric uid/gid? Allowing names is much more robust. If you migrate your postfix setup to a different existing machine, or if you have a catastrophic failure and restore by starting with a fresh distribution installation and then restoring the postfix configuration from backups, the uid/gid's for the real users that manage the virtual users may be different, but presumably the names will be the same. Now you have to fetch the old passwd and group files and translate the numbers in the virtual_uid_maps and virtual_gid_maps files. Is there some security or other reason that I am missing to not allow names? If not, would a feature request to allow this be welcome? ...Marvin
