# Blueprint to build postfix-2.1.1.
#
# The postfix package provides the 'sendmail' command among others.
#
# Source is from ftp://ftp.porcupine.org/mirrors/postfix-release/official/
#
# This blueprint has some prerequisites:
#
# 1. The sleepycat Berkeley db package must be installed.  There is
#    an architect blueprint provided for the db package.
# 2. A user account named 'postfix' must exist on the system on which
#    this blueprint is run.  See <architect>/extra/config-files/etc/passwd.
# 3. A group named 'postdrop' should exist on the build system with no
#    users as members.  See <architect>/extra/config-files/etc/group.
# 4. The files /etc/aliases /etc/aliases.db must exist on the system
#    where the postfix binary package is to be installed.  Without these
#    files postfix will start, but will not run correctly making trouble-
#    shooting difficult. See <architect>/extra/config-files/etc/ for the
#    aliases and aliases.db files.

# original source untouched, the contents of $SRC_DIR are first copied
# to $BUILD_DIR.  The copy in $BUILD_DIR is then modified to suit the
# configuration.

#
#
# Configuration is done by passing variables to make in order to over-
# ride the values defined in the Makefile.  The CCARGS variable is used
# to configure the the package to produce i386 compatible code.  All
# other parameters are configured in /etc/postfix/main.cf and are
# specified later as the package is installed into the staging area.

# Installing into the staging area is done a little differently with
# postfix when compared to the other architect package blueprints.  Rather
# than 'make install', postfix uses a shell script called postfix-install
# to handle the installation tasks.  postfix-install has a number of
# parameter that can be specified to fine-tune the installation.
