822header(1)
NAME
822header - print the header of a mail message
SYNOPSIS
822header
DESCRIPTION
822header reads an 822-format mail message from its stan
dard input, and prints the header of the message.
Under 822, the header is terminated by the end of the mes
sage or by a blank line. 822header also ends the header
if it sees a line that cannot be part of a valid header
field.
Note that the UUCP-style From_ line placed before a mes
sage in an mbox file is not part of the message.
