75<title>Installation of <application>Courier</application></title>
76
77<para> Before you compile the program, you need to create users and groups that
78will be expected to be in place when the install script executes. Add the users
79and groups with the following commands:</para>
80
81<screen><userinput><command>groupadd courier &amp;&amp;
82useradd -c 'Courier Mail Server' -d /dev/null \
83 -g courier -s /bin/false courier</command></userinput></screen>
84
85<para> You also need to create a bin user. If you already have a user
86named bin, this step can be safely ignored.</para>
87
88<screen><userinput><command>useradd -c 'bin' -d /dev/null -g bin -u 1 bin</command></userinput></screen>
89
90<para>This creates a
91<filename class="directory">/var/run/courier</filename> directory where
92all the <application>Courier</application> <acronym>MTA</acronym> pid
93files will exist. This will allow <filename>courierfilter.pid</filename>
94to be created. Without the <command>courierfilter</command> running, the
95<application>Courier</application> MTA will not work. Issue the
96following commands to create
97<filename class="directory">/var/run/courier</filename>:</para>
98
99<screen><userinput><command>mkdir /var/run/courier &amp;&amp;
100chown courier:courier /var/run/courier</command></userinput></screen>
101
102<para>Install <application>courier</application> by running the following
103commands:</para>
104
105<screen><userinput><command>./configure --prefix=/usr --libexecdir=/usr/lib/courier \
106 --datadir=/usr/share/courier --sysconfdir=/etc/courier \

119<title>Command explanations</title>
120
121<para><parameter>--libexecdir=/usr/lib/courier</parameter>: Specifies
122the directory which contains programs and libraries that cannot be
123directly executed from the command-line.</para>
124
125<para><parameter>--datadir=/usr/share/courier</parameter>: Specifies the
126directory where miscellaneous shell scripts,
127<application>Perl</application> scripts, and data files will be
128installed.</para>
129
130<para><parameter>--localstatedir=/var/spool/courier</parameter>:
131Specifies the directory that will hold the mail queue, and other
132temporary data.</para>
133
134<para><parameter>--with-piddir=/var/run/courier</parameter>: Specifies
135the directory where <application>Courier</application>'s
136<filename>PID</filename> files are stored when
137<application>Courier</application> is active.</para>
138
139<para><option>--disable-root-check</option>: Allows
140<application>Courier</application> to be built as the root user.</para>
141
142<para><parameter>--with-mailuser=courier</parameter>: All except two
143<application>Courier</application> daemons run as a non-privileged user.
144This option specifies the userid that <application>Courier</application>
145will install and run as.</para>
146
147<para><parameter>--with-mailgroup=courier</parameter>: like
148<option>--with-mailuser</option>, but specifies the group
149<acronym>ID</acronym>.</para>
150
151<para><option>--with-paranoid-smtpext</option>: Be paranoid when
152negotiating Courier-specific <acronym>ESMTP</acronym> extensions with
153remote servers. The <application>Courier</application> mail server
154defines and implements certain experimental <acronym>ESMTP</acronym>
155extensions: XVERP and XEXDATA. Problems may result in the event that
156someone else uses the same name to implement some other extension. If
157this option is specified, <application>Courier's</application>
158<acronym>ESMTP</acronym> server will also advertise a dummy
159<acronym>ESMTP</acronym> capability called XCOURIEREXTENSIONS, and will
160not recognize any Courier-specific extensions unless the remote mail
161server also advertises this dummy <acronym>ESMTP</acronym>
162capability.</para>
163
164<para><option>--disable-autorenamesent</option>: Do not rename the Sent
165folder every month. This option can also be controlled by the
166<envar>SQWEBMAIL_AUTORENAMESENT</envar> environment variable.</para>
167
168<para><option>--enable-workarounds-for-imap-client-bugs</option>: There
169are several confirmed bugs in some <acronym>IMAP</acronym> clients that
170do not properly implement the <acronym>IMAP</acronym>4rev1 protocol.
171This option enables some workarounds for those buggy
172<acronym>IMAP</acronym> clients. NOTE: <command>make check</command>
173will fail if this option is used. You should first configure without
174this option, and if all post-configuration tests succeed, rerun
175configure with this option and recompile.</para>
176
177<para><parameter>--with-db=gdbm</parameter>:
178<application>Courier</application> requires either the
179<application><acronym>GDBM</acronym></application> or the
180<application>DB</application> database library.
181<application><acronym>GDBM</acronym></application> is used if both are
182present. This option forces the selection of the GDBM database
183library since support for DB is broken at the current state.</para>
184
185<!-- # Note - Courier will build fine with <xref linkend="db"/>, but all
186the database files will not be created correctly -->
187
188<para><parameter>--with-ispell=/usr/bin/aspell</parameter>:
189<application>Courier</application>'s webmail server can use spell
190checking, if <command>configure</command> finds
191<application>ispell</application> or if you explicitly set the location
192of <application>aspell</application>.</para>
193
194<para><parameter>--enable-mimetypes=<replaceable>[location of mime.types
195file]</replaceable></parameter>: Use this switch if you receive an error
196saying that the <filename>mime.types</filename> file could not be found.</para>
