XMESSAGE DATA BASE
X
XThe message data base resides in the mail spool directory (de-
Xfined with the MAILDIR environment variable). There are various
Xclasses of message files:
X
X - mail received from the network
X
X - mail ready to send over the network
X
X - messages in preparation
X
XIn addition there are administrative files (LOGFILE, alias data
Xbase and communications parameters).
X
XEach message takes two files: a data file (with the actual mes-
Xsage) and a meta file (with originator or destination addresses,
Xor a one-line summary in case of a message in preparation).
X
XData/meta file names are constructed by concatenating a single-
Xcharacter prefix with a five-digit sequence number. Corresponding
Xdata and meta files have the same sequence number. The prefix
Xcharacters are:
X
X E message in preparation
X C description of message
X
X N message received from the net
X H originator address in case of an unread message
X O originator address in case of already read message
X
X D message ready to be sent over the net
X X destination of that message.
X
XAdministrative files are
X
X LOGFILE transaction log
X s00000 communications parameters
X a00000 alias data base
X
XAll files in the mail directory are ordinary text files, with a
Xpossible exception for the message in preparation (this depends
Xon the editor being used).
X
XFiles in the mail directory are normally write-protected to
Xprevent accidents.

X/* SYNOPSIS
X/* int call()
X/* DESCRIPTION
X/* call() is invoked when the user wants to contact the unix host.
X/* It asks for a uucp password. After the user has provided this
X/* the password is erased from the screen and the mail server is called
X/* by the cico file transfer program. Afterwards, the rmail program is
X/* invoked to extract originator addresses from new mail messages. In
X/* order to force a new mailbox display the current mail display is junked.
X/* FUNCTIONS AND MACROS
X/* kbdinp(), kbdrest(), invoke(), kbdinit(), errdisp(), junk_desk()
X/* COMMANDS
X/* cico remote login, file transfer
X/* rmail extract originator from new mail
