PLEASE resist the +temptation to list all parameters in the <a href="postconf.5.html">main.cf</a> file. Postfix +is supposed to be easy to configure. Listing all parameters in <a href="postconf.5.html">main.cf</a> +defeats the purpose. It is an invitation for hobbyists to make +random changes without understanding what they do, and gets them +into endless trouble. </p> + +<h2>General distributions: please include README or HTML files</h2> + +<p> Please provide the applicable README or HTML files. They are +referenced by the Postfix manual pages and by other files. Without +README or HTML files, Postfix will be difficult if not impossible +to configure. </p> + +<h2>Postfix Installation parameters</h2> + +<p> Postfix installation is controlled by a dozen installation +parameters. See the postfix-install and post-install files for +details. Most parameters have system-dependent default settings +that are configurable at compile time, as described in the <a href="INSTALL.html">INSTALL</a> +file. </p> + +<h2>Preparing a pre-built package for distribution to other +systems</h2> + +<p> You can build a Postfix package on a machine that does not have +Postfix installed on it. All you need is Postfix source code and +a compilation environment that is compatible with the target system. +</p> + +<p> You can build a pre-built Postfix package as an unprivileged +user. </p> + +<p> First compile Postfix. After successful compilation, execute: +</p> + +<blockquote> <pre> % <b>make package</b> </pre> +</blockquote> + +<p> With Postfix versions before 2.2 you must invoke the post-install +script directly (<tt>% <b>sh post-install</b></tt>). </p> + +<p> You will be prompted for installation parameters. Specify an +install_root directory other than /. The <a href="postconf.5.html#mail_owner">mail_owner</a> and <a href="postconf.5.html#setgid_group">setgid_group</a> +installation parameter settings will be recorded in the <a href="postconf.5.html">main.cf</a> +file, but they won't take effect until the package is unpacked and +installed on the destination machine. </p> + +<p> If you want to fully automate this process, specify all the +non-default installation parameters on the command line: </p> + +<blockquote> +<pre> % <b>make non-interactive-package install_root=/some/where</b>... +</pre> </blockquote> + +<p> With Postfix versions before 2.2 you must invoke the post-install +script directly (<tt>% <b>sh post-install -non-interactive +install_root...</b></tt>). </p> + +<p> With Postfix 3.0 and later, the command "make package name=value +..." will replace the string MAIL_VERSION in a configuration parameter +value with the Postfix release version. Do not try to specify +something like $<a href="postconf.5.html#mail_version">mail_version</a> on this command line. This produces +inconsistent results with different versions of the make(1) command. +</p> + +<h2>Begin Security Alert</h2> + +<p> <b> When building an archive for distribution, be sure to +archive only files and symbolic links, not their parent directories. +Otherwise, unpacking a pre-built Postfix package may mess up +permission and/or ownership of system directories such as / /etc +/usr /usr/bin /var /var/spool and so on. This is especially an +issue if you executed postfix-install (see above) as an unprivileged +user. </b> </p> + +<h2>End Security Alert</h2> + +<p> Thus, to tar up the pre-built package, take the following steps: +</p> + +<blockquote> <pre> +% cd INSTALL_ROOT +% rm -f SOMEWHERE/outputfile +% find . \! -type d -print | xargs tar rf SOMEWHERE/outputfile +% gzip SOMEWHERE/outputfile </pre> </blockquote> + +<p>This way you will not include any directories that might cause +trouble upon extraction. </p> + +<h2>Installing a pre-built Postfix package</h2> + +<ul> + +<li> <p> To unpack a pre-built Postfix package, execute the equivalent +of: </p> + +<pre> +# umask 022 +# gzip -d <outputfile.tar.gz | (cd / ; tar xvpf -) </pre> + +<p> The umask command is necessary for getting the correct permissions +on non-Postfix directories that need to be created in the process. +</p> + +<li> <p> Create the necessary <a href="postconf.5.html#mail_owner">mail_owner</a> account and <a href="postconf.5.html#setgid_group">setgid_group</a> +group for exclusive use by Postfix. </p> + +<li> <p> Execute the postfix command to set ownership and permission +of Postfix files and directories, and to update Postfix configuration +files. If necessary, specify any non-default settings for <a href="postconf.5.html#mail_owner">mail_owner</a> +or <a href="postconf.5.html#setgid_group">setgid_group</a> on the postfix command line: </p> + +<pre> +# postfix set-permissions upgrade-configuration \ + <a href="postconf.5.html#setgid_group">setgid_group</a>=xxx <a href="postconf.5.html#mail_owner">mail_owner</a>=yyy +</pre> + +<p> With Postfix versions before 2.1 you achieve the same result +by invoking the post-install script directly. </p> + +</ul> + +</body> + +</html> |
