32 The <application>Postfix</application> package contains a Mail Transport
33 Agent (MTA). This is useful for sending email to other users of your host
34 machine. It can also be configured to be a central mail server for your
35 domain, a mail relay agent or simply a mail delivery agent to your local
36 Internet Service Provider.

126 Before you compile the program, you need to create users and groups that
127 will be expected to be in place during the installation. Add the users
128 and groups with the following commands issued by the
129 <systemitem class="username">root</systemitem> user:

141
142 <para>
143 The README files are formatted to be read with a pager like
144 <application>less</application> or <application>more</application>.
145 If you want to use a text editor, make them legible with the
146 following sed:
147 </para>
148
149<screen><userinput>sed -i 's/.\x08//g' README_FILES/*</userinput></screen>
150
151 <para>
152 The <application>Postfix</application> source tree does not contain a
153 <filename>configure</filename> script, rather the makefile in the
154 top-level directory contains a <option>makefiles</option> target that
155 regenerates all the other makefiles in the build tree. If you wish to
156 use additional software such as a database back-end for virtual users,
157 or TLS/SSL authentication, you will need to regenerate the makefiles
158 using one or more of the appropriate <envar>CCARGS</envar> and
159 <envar>AUXLIBS</envar> settings listed below.
160 </para>
161
162 <note>
163 <para>
164 For all variants of the CCARGS you should ensure that -DNO_NIS is
165 specified so that the build does not attempt to access an rpcsvc
166 header which do not exist in BLFS. If &berkeley-db; is
167 not installed, -DNO_DB needs to be specified as well.
168 </para>

184 Next, the <envar>CCARGS</envar> and the <envar>AUXLIBS</envar>
185 variables are filled with settings depending on the actual
186 system configuration. If an optional package is installed but
187 should <emphasis>not</emphasis> be included in the

189 corresponding <code>if [ ... ]; then</code> scriptlets.

429 The BLFS editors recommend to use LMDB instead of Berkeley DB for

446 allowing clients on your network with non-standard SMTP implementations
