MAKEPERCENTRELAY(8)	    Double Precision, Inc.	   MAKEPERCENTRELAY(8)

NAME
       makepercentrelay	- Build	a list of %-relayed domains

SYNOPSIS
       makepercentrelay

DESCRIPTION
       makepercentrelay	reads /usr/local/etc/courier/esmtppercentrelay.dir and
       creates /usr/local/etc/courier/esmtppercentrelay.dat which is a binary
       database	file. The files	/usr/local/etc/courier/esmtppercentrelay and
       /usr/local/etc/courier/esmtppercentrelay.dat specify a list of
       "percent-hack" domains.	/usr/local/etc/courier/esmtppercentrelay is a
       plain text file,	containing one domain per line.	The Courier mail
       server loads the	contents of /usr/local/etc/courier/esmtppercentrelay
       into memory, so if you have a lot of domains, you will want to use the
       binary database file. The makepercentrelay command reads
       /usr/local/etc/courier/esmtppercentrelay.dir, which can be either a
       plain text file itself, or a directory containing plain text files. All
       files in	the subdirectory are concatenated, and the binary database
       file is created from the	result.

       the Courier mail	server can use both
       /usr/local/etc/courier/esmtppercentrelay	and
       /usr/local/etc/courier/esmtppercentrelay.dat at the same	time. Usually
       you would put a couple of your most frequent domains in
       /usr/local/etc/courier/esmtppercentrelay, then put the rest in
       /usr/local/etc/courier/esmtppercentrelay.dir, and use makepercentrelay
       to turn it into a database file.

       "percent-hack" domains are a list of domains for	which the Courier mail
       server accepts mail via ESMTP addressed as
       "local%percent.hack.domain@local.domain", where "percent.hack.domain"
       is a domain found in /usr/local/etc/courier/esmtppercentrelay or
       /usr/local/etc/courier/esmtppercentrelay.dat, and "local.domain"	is any
       domain found in /usr/local/etc/courier/locals. The Courier mail server
       removes the local domain, and rewrites the address as
       "local@percent.hack.domain", then attempts to deliver it.

       The percent hack	applies	only to	mail received via ESMTP. The Courier
       mail server does	not check this list of domains if the message is
       received	via any	other way (such	as by running /usr/local/bin/sendmail
       directly	from the command line).	"percent.hack.domain" would likely to
       be a domain that	the Courier mail server	knows how to handle via	some
       other means. It might be	an entry in /usr/local/etc/courier/aliases, or
       an entry	in /usr/local/etc/courier/esmtproutes.
