The permissions here are unexpected. procmail cares about clearing group and other permissions-- unless GROUP_PER_USER is set (cf http://partmaps.org/era/procmail/mini-faq.html#group-writable), which usually would be appropriate for FreeBSD since it encourages all userids to also have a corresponding groupid.
