NAME
       rpc.dracd - Dynamic Relay Authorization Control server

SYNOPSIS
       rpc.dracd [-i ] [ -e expire ] [ dbfile ]

AVAILABILITY
       ftp.cc.umanitoba.ca:/src

DESCRIPTION
       rrppcc..ddrraaccdd is the Dynamic Relay Authorization Control server.  It uses
       the Berkeley db package to maintain a relay authorization map for
       sendmail, by default //uussrr//llooccaall//eettcc//ddrraaccdd..ddbb.  POP and IMAP mail
       servers make an RPC call to add an entry to the authorization cache
       after they have authenticated each user.  The daemon, rpc.dracd, adds
       or updates entries in the cache, and periodically expires old entries.
       Only trusted mail servers are permitted to communicate with rpc.dracd,
       as controlled by //uussrr//llooccaall//eettcc//ddrraaccdd..aallllooww.  If this file does not
       exist, all local IP addresses are permitted.

   Allow File Format
       The Allow File file consists of entries of the form:

              nneettmmaasskk netaddr

       where both netmask and netaddr must be dotted quads.

OPTIONS
       -i             Initialize the database on startup.

       -e expire      Set the expire time limit.  expire is the number of
                      minutes the entries will remain in the database.  It
                      defaults to 30 minutes.

       dbfile         Use a different database file name.
