From b0591e84e91e6fc8900d5e755acd7f0b48ac835c Mon Sep 17 00:00:00 2001
From: Peter Wemm <peter@FreeBSD.org>
Date: Tue, 29 Oct 1996 05:22:52 +0000
Subject: [PATCH] Merge in our changes from src/libexec/mail.local.  This
 version doesn't violate disk quotas, has more robust locking, is still being
 developed, etc.  The main changes merged in were the ability to not fsync()
 the mailbox, not do biff/comsat broadcasts, man page fixes.
