Some of these questions were never asked, but I thought they will be
some time. Some <em>were</em> asked.
<h4>General Questions</h4>
<ul>
<li><a href="#1_0">1.0: When do I need MasqMail?</a></li>
<li><a href="#1_1">1.1: When do I <em>not</em> need MasqMail?</a></li>
<li><a href="#1_2">1.2: Can I retrieve mail with MasqMail?</a></li>
<li><a href="#1_3">1.3: Is there a mailing list for MasqMail?</a></li>
</ul>
<h4>Setup</h4>
<ul>
<li><a href="#2_0">2.0: After starting masmail, I get the following
message: "could not gain root privileges. Is the setuid bit set?"</a></li>

message: "bind: (terminating): Address already in use"</a></li>
</ul>

</ul>

<h4>Bugs</h4>
<ul>
<li><a href="#5_0">5.0: I found a bug.</a></li>

</ul>
<a name="1_0"> <h4>1.0: When do I need MasqMail?</h4></a>
<p> You do not <em>need</em> it. But it makes sending mails via a
dialup connection a lot easier.</p>
<p>It is useful if you dial to the internet from time to time via a
modem and connect to different providers, each one with a different
configuration. Other MTAs are not flexible enough if you have to send
mails via different mail servers for each provider. With MasqMail you
can configure a different one for each provider and even set your
return addresses differently.</p>
<p>It is also useful if you have a LAN with a gateway which is
connected to the internet via a modem because you can rewrite your
address depending on whether the recipients are <em>inside</em> or
<em>outside</em> your LAN. So responses and delivery failures on your
LAN will be sent to you without leaving it, while those outside will
be delivered to your address outside. (But it does not yet send
delivery failures itself yet.)</p>
<a name="1_1"><h4>1.1: When do I <em>not</em> need MasqMail?</h4></a>
<p>The use of MasqMail is <em>strongly</em> discouraged if you have a
permanent connection to the internet. First because it does not have
the ability to block relaying (it relays every mail) and second
because there are no capabilities to protect against SPAM. You will
not take advantages of its features anyway.</p>
<a name="1_2"><h4>1.2: Can I retrieve mail with MasqMail?</h4></a>
<p>Not directly. But you can use fetchmail or other pop/imap clients
to feed it. Possibly POP3 support will be implemented some time, but
fetchmail is an excellent program so possibly there is no need.</p>
<a name="1_3"><h4>1.3: Is there a mailing list for MasqMail?</h4></a>
<p>Yes, there is! See <a href="http://www.innominate.org/mailman/listinfo/masqmail">here</a>.</p>
<a name="2_0"><h4>2.0: After starting masmail, I get the following
message: "could not gain root privileges. Is the setuid bit set?"</h4></a>
<p>Set the set-user-id-bit with chmod u+s /usr/sbin/masqmail.</p>
<a name="2_1"><h4>2.1: After starting masmail, I get the following
message: "bind: (terminating): Address already in use"</h4></a>
<p>This means that there is already a process listening on a port,
usually 25. You either have another MTA running in background
(sendmail, exim, etc...) or another instance of masqmail.</p>
<p>It may also mean that the ports you configured MM to listen to
(with 'listen_addresses') are on the same IP address, eg. you may have
set your hostname to 127.0.0.1 and try to listen on localhost and your
host name. In this case either set your hostname to another IP address
or delete one of the conflicting entries.</p>
<a name="3_0"><h4>3.0: My friends told me that they do not see my full
name in their inbox, although it is configured in my mail
client.</h4></a>
<p>You probably used the <b>map_h_from_addresses</b> feature in the
route configuration and forgot to set your real name. The syntax
is:</p>
<pre>
map_h_from_addresses = "charlie:Charlie Miller <cmiller@foo.com>";
</pre>
<p>Do not forget the <em>Charlie Miller</em>.</p>
<a name="4_0"><h4>4.0: With connection method <em>file</em>, I get the
following message in the log file: "Could not open /tmp/connect_route:
Permission denied".</h4></a>
<p>In your ip-up script, you have to set read permission to the user
masqmail runs as. After you write the file with the connection name,
set read permission to all with chmod ugo+r <em>file</em>.
<a name="4_1"><h4>4.1: With connection methed <em>file</em>, I get the following message in the log file: "route with name <em>name</em> not found.".</h4></a>
<p>Check whether the name in the file is really identical to name you
gave to the route configuration (case sensitive!). Maybe there is a
linefeed after the name in the file. Write it with echo -n.</p>
<a name="5_0"><h4>5.0: I found a bug.</h4></a>
<p>Make sure you are using the newest version, in case of doubt search
it in <a href="http://www.freshmeat.net">freshmeat</a>. If you do, tell
<a href = "mailto:Oliver Kurth <kurth@innominate.de>">me</a>. See
also the section <a href="index.html#bugs">bugs</a> on the <a
href="index.html">main</a> page.</p>
<a name="5_1"><h4>5.1: I think I found a bug, but I am not sure
whether I configured MasqMail incorrectly.</h4></a>
<p>Don't care. Tell <a href = "mailto:Oliver Kurth
<kurth@innominate.de>">me</a>. Or write to the <a href="http://www.innominate.org/mailman/listinfo/masqmail">mailing list</a>.</p>
