mailbox in .49b7

[Eugene Crosser <crosser@online.ru>]

Matti,

'-H' option in mailbox program (allow 8bit in headers) stopped working.
Moreover, attemped QP encoding is incorrect: *any* 8bit character is
converted to '=FF'!  Have to defer installing in on the main production
relay...

Also, noticed a strange thing: a few messages are stuck in the scheduler
queue for smtp delivery, and mailq only shows them occationaly.  Here
are 'mailq' commands run *immediately* one after one:

crosser@chronos:/src/zmailer/zmailer-2.99.49b7/$ mailq
smtp/it.ru:
        68047-25772:    (retry in 4s, expires in 2d22h, tries=1)
crosser@chronos:/src/zmailer/zmailer-2.99.49b7/$ mailq
smtp/nic.funet.fi:
        68060-25772:    (retry in 52s, expires in 1d20h, tries=1)
crosser@chronos:/src/zmailer/zmailer-2.99.49b7/$ mailq
smtp/bm.com:
        68058-25772:    (retry in 1m, expires in 1d20h, tries=1)
smtp/nic.funet.fi:
        68060-25772:    (retry in 46s, expires in 1d20h, tries=1)
crosser@chronos:/src/zmailer/zmailer-2.99.49b7/$
