[Slackbuilds-users] postfix version 3.2.4

[Konrad J Hambrick]

All --

I too use the SBo postfix.SlackBuild via a wrapper script ( attached ) so
that I am consistent with my opptions.

In addition, the postfix.SlackBuild wrapper script includes a reminder so I
'do it right' each time.

Sorry if I gave the impression that I wanted to change the SBo
postfix.SlaokBuild to the Slackware Current SlackBuild.

I didn't mean to imply that :)

#
# Postfix is Wietse Venema's mailer that started life as an alternative to the
# widely-used Sendmail program. It attempts to be fast, easy to administer, and
# secure, while at the same time, being sendmail compatible enough to not upset
# existing users. Thus, the outside has a sendmail-ish flavor, but the inside is
# completely different.
# 
# This script builds postfix with optional support for Dovecot SASL, Cyrus SASL
# can be enabled with:
# 
#   SASL=cyrus ./postfix.SlackBuild
# 
# You can also enable support for MySQL:
# 
#   DATABASE=mysql ./postfix.SlackBuild
# 
# PostgreSQL support can be enabled with:
# 
#   DATABASE=pgsql ./postfix.SlackBuild
# 
# On systems with multiple instances, add major version, eg: DATABASE=pgsql-9.5
# 
# This script will find support for BerkleyDB and PCRE automagically; TLS support
# requires openssl package, openssl-solibs alone is not enough. Additionally, this
# script doesn't add postfix user and groups, instead it offers sane defaults that
# won't conflict with system users and groups, and other scripts from the SBo.
# 
# Package created with this script will conflict with stock sendmail package, you
# *should* remove sendmail before installing postfix, otherwise sendmail updates
# could break your postfix instance.
# 
# When upgrading from an older postfix version, make sure the variables such as
# html_directory and readme_directory in /etc/postfix/main.cf point to the new
# location. These can also be fixed later, afterwards make sure to run:
# 
#   postfix set-permissions
# 
# Furthermore, many of the utilities in postfix have multiple manpages such as
# postconf(5) and postconf(8). Use man -k to find them, and don't forget to
# subscribe to the postfix-users mailing list!
#
# the README is there
