In that case, `mbox` should not be the default configuration, and `mail(1)` et al should support alternatives. Unless I am missing something, there are no tools that support reading from maildir in the base system. Furthermore, there are variations of mbox that do not mangle *any* messages, since they use reversible quoting. Proper use of MIME encoding also avoids the problem, but none of the tools in the base system support decoding it, and none of the programs in the base system that send mail use it (another bug). I don’t particularly care which of the various variations on mbox is used, provided that mail(1) and mail.local(8) are consistent with each other. Sincerely, Demi
