NAME

       makepercentrelay - Build a list of %-relayed domains

SYNOPSIS

       makepercentrelay

DESCRIPTION

       makepercentrelay reads /etc/courier/esmtppercentrelay.dir and creates
       /etc/courier/esmtppercentrelay.dat which is a binary database file. The
       files /etc/courier/esmtppercentrelay and
       /etc/courier/esmtppercentrelay.dat specify a list of "percent-hack"
       domains.  /etc/courier/esmtppercentrelay is a plain text file,
       containing one domain per line. The Courier mail server loads the
       contents of /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 /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 /etc/courier/esmtppercentrelay and
       /etc/courier/esmtppercentrelay.dat at the same time. Usually you would
       put a couple of your most frequent domains in
       /etc/courier/esmtppercentrelay, then put the rest in
       /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 /etc/courier/esmtppercentrelay or
       /etc/courier/esmtppercentrelay.dat, and "local.domain" is any domain
       found in /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/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 /etc/courier/aliases, or an entry
       in /etc/courier/esmtproutes.
