Mailbox delivery of true binary body parts

[Eugene Crosser <crosser@online.ru>]

Some time ago I reported to mea that messages containg binary data
(Content-Transfer-Encoding: 8bit and real non-text bytes inside)
cannot be delivered locally via mailbox program, although they are
correcly relayed over smtp transport.  Today, it seems that I fixed
the problem.  Patch follows.  I hope Matti will look at it.
