     qmail-queue - queue a mail message for delivery

DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
     qqqqmmmmaaaaiiiillll----qqqquuuueeeeuuuueeee reads a mail message from descriptor 0.  It then
     reads envelope information from descriptor 1.  It places the
     message into the  outgoing  queue  for  future  delivery  by
     qqqqmmmmaaaaiiiillll----sssseeeennnndddd.

     The envelope information is an envelope sender address  fol-
     lowed by a list of envelope recipient addresses.  The sender
     address is preceded by the letter F and terminated  by  a  0
     byte.   Each  recipient  address is preceded by the letter T
     and terminated by a 0 byte.  The list of recipient addresses
     is  terminated by an extra 0 byte.  If qqqqmmmmaaaaiiiillll----qqqquuuueeeeuuuueeee sees end-
     of-file before the extra 0 byte, it aborts  without  placing
     the message into the queue.

     Every envelope recipient address should contain a  username,
     an @ sign, and a fully qualified domain name.

     qqqqmmmmaaaaiiiillll----qqqquuuueeeeuuuueeee always adds a RRRReeeecccceeeeiiiivvvveeeedddd line to the  top  of  the
     message.   Other than this, qqqqmmmmaaaaiiiillll----qqqquuuueeeeuuuueeee does not inspect the
     message and does not enforce any restrictions  on  its  con-
     tents.   However,  the  recipients  probably expect to see a
     proper header, as described in qqqqmmmmaaaaiiiillll----hhhheeeeaaaaddddeeeerrrr((((5555)))).

     Programs included with qmail which invoke  qqqqmmmmaaaaiiiillll----qqqquuuueeeeuuuueeee  will
     invoke the contents of $$$$QQQQMMMMAAAAIIIILLLLQQQQUUUUEEEEUUUUEEEE instead, if that environ-
     ment variable is set.

     qqqqmmmmaaaaiiiillll----qqqquuuueeeeuuuueeee imposes two constraints on the queue  structure:
     each mmmmeeeessssssss subdirectory must be in the same filesystem as the
     ppppiiiidddd directory; and each ttttooooddddoooo subdirectory  must  be  in  the
     same filesystem as the iiiinnnnttttdddd directory.

     qqqqmmmmaaaaiiiillll----qqqquuuueeeeuuuueeee does not print diagnostics.  It exits  0  if  it
     has successfully queued the message.  It exits between 1 and
     99 if it has failed to queue the message.

     All qqqqmmmmaaaaiiiillll----qqqquuuueeeeuuuueeee error codes between 11 and 40 indicate  per-
