NAME
      in.comsat, comsat - biff server
 


SYNOPSIS
      /usr/sbin/in.comsat
 


DESCRIPTION
      comsat is the server process which listens  for  reports  of
      incoming  mail  and  notifies users who have requested to be
      told  when  mail  arrives.  It  is  invoked  as  needed   by
      inetd(1M), and times out if inactive for a few minutes.
 
      comsat listens on a datagram port associated with  the  biff
      service  specification  (see  services(4)) for one line mes-
      sages of the form
 
           user@mailbox-offset
 
 
      If the user specified is logged in to  the  system  and  the
      associated  terminal has the owner execute bit turned on (by
      a biff y), the offset is used as  a  seek  offset  into  the
      appropriate mailbox file, and the first 7 lines or 560 char-
      acters of the message are printed on  the  user's  terminal.
      Lines  which  appear  to be part of the message header other
      than the From, To,  Date, or Subject lines are  not  printed
      when displaying the message.
