NAME
       rpc.dracd - Dynamic Relay Authorization Control server

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

AVAILABILITY
       ftp.cc.umanitoba.ca:/src

DESCRIPTION
       rpc.dracd  is  the Dynamic Relay Authorization Control server.  It uses
       the Berkeley db package to maintain a relay authorization map for send‐
       mail,  by  default  /usr/local/etc/dracd.db.  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 /usr/local/etc/dracd.allow.  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:

	      netmask 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 min‐
		      utes the	entries	 will  remain  in  the	database.   It
		      defaults to 30 minutes.

       dbfile	      Use a different database file name.

FILES
       /usr/local/etc/dracd.db	     default database file
       /usr/local/etc/dracd.allow    default allow file.

SEE ALSO
       dracauth(3)

NOTES
       The following signals have the specified effect when sent to the server
       process using the kill(1) command.

       SIGTERM		   closes the database and terminates the server.
