H A header definition. There can be many H lines in the queue-control
file. Header definitions follow the header definition syntax in the
configuration file.
P The current message priority. This is used to order the queue.
Higher numbers mean lower priorities. The priority decreases (that
is, the number grows) as the message sits in the queue. The initial
priority depends on the message precedence, the number of
recipients, and the size of the message.
M A message. This line is printed by the mailq command and is
generally used to store status information (that is, the reason the
message was queued). It can contain any text.
R A recipient address. Normally this has already been completely
aliased, but it is actually re-aliased when the queue is processed.
There is one line for each recipient.
S The sender address. There can be only one sender address line.
T The job creation time (in seconds since January, 1970). This is used
to determine when to time out the job.
