<p>You need a user and a group for masqmail to run, I suggest user
'mail' and group 'trusted'. Say:</p>
<pre>
groupadd -g 42 trusted
useradd -u 42 -g 42 -d / -s /bin/sh -c "Mail Transfer Agent" mail
</pre>
<p>If you use other names than <i>mail</i> and <i>trusted</i> use the options
described below for configure. The 42 is just a suggestion, you can
use any number you like, but preferably one < 100. It does not have
to be the same for the user 'mail' and the group 'trusted'.</p>
<p>Compliling is a matter of the usual procedure:</p>
In the source directory, after unpacking do:<br>
<pre>
./configure
make
make install
</pre>
<p>Optionally, after you have called make, you can make some tests in
the tests directory. Read the README in that directory for
instructions.</p>
<h4>Additional options for configure:</h4>
<p>
<b>--with-user=USER</b> sets the user as which MasqMail will run. Default is
<i>mail</i>. USER has to exist before you 'make install'.
</p><p>
<b>--with-group=GROUP</b> sets the group as which MasqMail will run. Default
is <i>trusted</i>. GROUP has to exist before you 'make install'.
</p><p>
<b>--with-logdir=LOGDIR</b> sets the directory where MasqMail stores its log
files. It will be created if it does not exist. Default is /var/masqmail/.
</p><p>
<b>--with-spooldir=SPOOLDIR</b> sets the directory where MasqMail stores its
spool files. It will be created if it does not exist. Default is
/var/spool/masqmail/.
</p>
<h4>After make install</h4>
<p>
You can also use these instructions to omit 'make install' if you do
not want to use it.
</p><p>
Check that 'make install' worked correctly. The following command:
</p><p><pre>
ls -ld /usr/sbin/masqmail /var/masqmail/ /var/spool/masqmail /var/spool/masqmail/input
</pre></p><p>
should give output similar to
</p><p>
<pre>
-rwsr-xr-x 1 root root 86955 Oct 14 14:27 /usr/sbin/masqmail
drwxr-xr-x 2 mail trusted 1024 Oct 14 14:29 /var/masqmail/
drwxr-xr-x 3 mail trusted 1024 Oct 14 14:27 /var/spool/masqmail
drwxr-xr-x 2 mail trusted 1024 Oct 14 18:32 /var/spool/masqmail/input
</pre>
</p>
<p>
(important is the set-user-id bit for /usr/sbin/masqmail and the
ownership of all items).
</p>
<p>Edit the configuration files. You can use the files from the
examples directory as a template. Copy masqmail.conf to
/etc/maqmail.conf, the others to the location given in
masqmail.conf.</p>
<p>If you already have an MTA (eg. sendmail) installed, move that to
another location:</p>
mv /usr/sbin/sendmail /usr/sbin/sendmail.orig<br>
<p>Then make a link to the new MTA:</p>
<pre>
ln -s /usr/sbin/masqmail /usr/sbin/sendmail
</pre>
<p>Now every mailer that used to call sendmail will now call
masqmail. You can now kill your old sendmail if it is running and
start masqmail. Usually this is done with the startup scripts. For
SuSE this would be (as root):</p>
<pre>
/sbin/init.d/sendmail stop
/sbin/init.d/sendmail start
</pre>
<p>or shorter:</p>
<pre>
/sbin/init.d/sendmail restart<br>
</pre>
<p>You can also start it with:</p>
<pre>
/usr/sbin/sendmail -bd -q30m<br>
</pre>
<p>You can also let it be called from inetd (with the -bs option), but
this is untested.</p>
<h4>Configuring for online delivery</h4>
<p>Now you have to set up the online configuration. The trick is to
tell your ip-up script the connection name. You could use the IP
number of the far side of the ppp link, but this is a pain and may
change each time. But you can give it an additional argument via pppd
with ipparam. Somewhere in your dial up script you have a line similar
to:</p>
<pre>
/usr/sbin/pppd /dev/ttyS1 connect "/usr/sbin/chat -t 90 -f
${CHATFILE}" -d -d -d user user@somewhere file ${OPTIONS}
</pre>
<p>Just add 'ipparam FastNet' in the command line for pppd if your ISP
has the name FastNet. The ip-up script will then get 'FastNet' as a
sixth parameter. In your ip-up script you can then call masqmail with</p>
<pre>
/usr/sbin/masqmail -qo $6
</pre>
<p>instead of 'sendmail -q', if you had that in the script
before. Masqmail will then read the route configuration specified for
the connection name 'FastNet' and deliver the mail destined to the
internet. See the <a href="config.html">configuration manual</a> on how
to write a route configuration or use one of the examples as a
template. <em>I do not know how do configure that for an ISDN adapter,
but I am sure you will find something similar in the man
pages.</em></p>
<p>If you want mail that is received by masqmail from your local
net to be delivered immediately using the route configuration, you
have two possibilities:<p>
<p>
<ul>
<li>if you are using the masqdialer system, you just have to set the
variables <b>online_detect</b> to <i>mserver</i> and
<b>mserver_iface</b> to the interface mserver is listening to.</li>
<li>otherwise you have to add two commands in your ip-up script:<br>
echo -n $6 > /tmp/connect_route<br> chmod 644 /tmp/connect_route<br>
and you have to remove the file <i>/tmp/connect_route</i> in your
ip-down script:<br> rm /tmp/connect_route.<br> Then you have to set
<b>online_detect</b> to <i>file</i> and <b>online_file</b> to
<i>/tmp/connect_route</i>. </li>
</ul>
</p>
<p>See the route documentation for more.</p>
