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
|
|
|
|
|
|
|
|
|
|
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!
