34 <h2>Introduction</h2>
|
|
|
35
|
|
|
36 <p>MasqMail is a mail server designed for hosts that do not have a
|
|
|
37 permanent internet connection eg. a home network or a single host at
|
|
|
38 home. It has special support for connections to different ISPs. It
|
|
|
39 replaces sendmail or other MTAs such as qmail or exim.<p>
|
|
|
40
|
|
|
41 <p>Since version 0.0.10 it supports alias address expansion and can
|
|
|
42 deliver to pipes.</p>
|
|
|
43
|
|
|
44 <p>MasqMail is released under the <a href="http://www.fsf.org">GPL</a>
|
|
|
45 license.</p>
|
|
|

|
|
|
66 <a name="how"></a> <h2>How it works</h2>
|
|
|
67
|
|
|
68 <p>When offline, MasqMail queues all mail with a destination outside
|
|
|
69 of the local network. When you connect to the internet, masqmail will
|
|
|
70 be called with a connection name as an argument. MasqMail then sends
|
|
|
71 the queued mail to the configured mailserver for that ISP. When a
|
|
|
72 message from the local net is received when online, MasqMail delivers
|
|
|
73 it immediately. If there is no mail server for that ISP, MasqMail can
|
|
|
74 also send the mails directly to their destinations.</p>
|
|
|
75
|
|
|
76 <p>For each ISP different return addresses can be configured. This
|
|
|
77 makes it possible to get around spam traps which desire your return
|
|
|
78 address to be from the same domain as the host the mail is coming
|
|
|
79 from. This is not a problem if you always connect to a single ISP, but
|
|
|
80 is one if you use different ones from time to time. It also makes it
|
|
|
81 possible to configure your mailer to a return address on your local
|
|
|
82 network which maybe totally unknown outside. So delivery failure
|
|
|
83 messages originating on your local net can be sent directly to you,
|
|
|
84 while those that occur outside will be sent to the configured
|
|
|
85 address. <em>(Note that the return path is different from the From:
|
|
|
86 address or the Reply-to: address. You can still have a single address
|
|
|
87 where you want replys to be sent to).</em></p>
|
|
|
88
|
|
|
89 <p>When offline, MasqMail behaves just like any other ordinary mail
|
|
|
90 server (with a few limitations, but these will be fixed in the
|
|
|
91 future).</p>
|
|
|
92
|
|
|
93 <p>To detect its online status, MasqMail can take advantage of the <a
|
|
|
94 href="http://cpwright.com/mserver/">masqdialer</a> system. But it also
|
|
|
95 works well without it.</p>
|
|
|
96
|
|
|
97 <p>See the <a href="manual.html">manual</a> for more information.</p>

|
|
100 <h2>Platforms</h2>
|
|
|
101
|
|
|
102 <p>MasqMail is being developed for Linux. It may run on other Un*x like
|
|
|
103 platforms, but it will certainly not run on Windows or a
|
|
|
104 Mac. Currently I see no point in porting it to other platforms.</p>
|
|
|
105
|
|
|
106 <p>But it is possible to use a Windows (or Mac or any system that
|
|
|
107 knows about SMTP) host as a client. Just configure your mailer to use
|
|
|
108 the machine MasqMail is running on as your mail server.</p>
|
|
|
109
|
|
|
110 <a name="limit"></a>
|
|
|
111 <h2>Limitations</h2>
|
|
|
112
|
|
|
113 <p>MasqMail is still in an early stage of development so use it with
|
|
|
114 caution! There may still be serious bugs in it, so mail might
|
|
|
115 get lost. But in the nearly two years of its existence so far there
|
|
|
116 was only one time a bug which caused mail retrieved via pop3 to be
|
|
|
117 lost in rare circumstances.</p>
|
|
|
118
|
|
|
119 <p>There are also some features every MTA should have:</p>
|
|
|
120
|
|
|
121 <ul>
|
|
|
122
|
|
|
123 <li> it does not use .forward files (but it uses alias files since 0.0.10)</li>
|
|
|
124 <li> it does not support retrieving mail from a multi-drop mailboxes</li>
|
|
|
125
|
|
|
126 </ul>
|
|
|
127
|
|
|
128 <p>But these are worked on.</p>
|
|
|
129
|
|
|
130 <p>MasqMail is <em>not</em> designed to run on a host with a permanent
|
|
|
131 internet connection. It does not have the ability to check for spam
|
|
|
132 mail and it will relay everything from everywhere to everywhere. Use
|
|
|
133 another mail server such as <a href="http://www.exim.org">exim</a>
|
|
|
134 for permanent connections.</p>
|
|
|
135
|
|
|
136 <p>BTW: I am already using it...</p>
|
|
|
137
|
|
|
138 <a name="secure"></a>
|
|
|
139 <h2>Security</h2>
|
|
|
140
|
|
|
141 <p>I hope that I have not done anything stupid, but there may be
|
|
|
142 security holes in it. If you find one, please tell me.</p>
|
|
|
143
|
|
|
144 <p>MasqMail does not listen to a port to the internet (unless you
|
|
|
145 manage to configure it to do so... which is pretty senseless anyway),
|
|
|
146 so that door is closed.</p>
|
|
|
147
|
|
|
148 <p>MasqMail is designed to run with an own user and group id. It uses
|
|
|
149 root permission only when necessary, ie. to open a listening port and
|
|
|
150 to change identity to some user when it delivers local mail.</p>
|
|
|
151
|
|
|
152 <a name="require"></a>
|
|
|
153 <h2>Requirements</h2>
|
|
|
154
|
|
|
155 <p>MasqMail requires glib 1.2 or greater. You may find this strange
|
|
|
156 since glib was originally written for gimp and is used by <a
|
|
|
157 href="http://www.gtk.org">gtk</a>, but glib does not necessarily have
|
|
|
158 to do with GUIs. It has some useful list and string functions, and I
|
|
|
159 use only these. This may change in the future when I write my own
|
|
|
160 utilities.</p>
|
|
|
161
|
|
|
162 <p>I develop MasqMail with a Debian woody distribution, Kernel 2.4.x and
|
|
|
163 glibc (libc6) with gcc 2.95. There have been reports that it compiles and
|
|
|
164 runs under Redhat, SuSE, slackware, with libc5 (since 0.0.4) and Kernel
|
|
|
165 2.0.x and 2.2.x, and FreeBSD, OpenBSD and NetBSD.</p>

217 <h2>Documentation</h2>
|
|
|
218
|
|
|
219 <p>masqmail comes with a bunch of man pages, these are also available
|
|
|
220 <a href="manual.html">online</a>. Some people have written introductory pages
|
|
|
221 for the initial installation:</p>
|
|
|
222
|
|
|
223 <p>
|
|
|
224 Christoph Hertel has written a <a href="http://instruction.at/mmquickconfig">quick help</a> page for masqmail.

|
|
|
228 <h2>Roadmap</h2>
|
|
|
229
|
|
|
230 <p>MasqMail will be optimized for slow connections. It uses ESMTP
|
|
|
231 pipelining both when sending and receiving and sends all messages to a
|
|
|
232 single host in a single connection.</p>
|
|
|
233
|
|
|
234 <p>Apart from the missing things mentioned above, I plan to implement
|
|
|
235 the following features:</p>
|
|
|
236
|
|
|
237 <ul>
|
|
|
238 <li>ODMR support as a client</li>
|
|
|
239 <li>POP3 multidrop support</li>
|
|
|
240 </ul>

|
|
243 <h2>Mailing List</h2>
|
|
|
244

245 <p>There is now a <a

|
|
251 <h2>Bugs and Feedback</h2>
|
|
|
252
|
|
|
253 <p>Since MasqMail is very young, bugs are quite probable. If you
|
|
|
254 encounter one, send it to <a
|
|
|
255 href="mailto:oku@masqmail.cx">me</a>. Please tell me the versions of:
|
|
|
256 <ul>
|
|
|
257 <li>MasqMail</li>
|
|
|
258 <li>libc</li>
|
|
|
259 <li>OS (Linux) (use uname -a)</li>
|
|
|
260 <li>glib (use glib-config --version)</li>
|
|
|
261 <li>the compiler (use gcc -v)</li>
|
|
|
262 </ul>
|
|
|
263
|
|
|
264 <p>If not already so, set the debug level to at least 5 and send the
|
|
|
265 debug.log (only the important part please...).</p>
|
|
|
266
|
|
|
267 <p>To improve MasqMail, bug reports are really needed! The more bug
|
|
|
268 reports I get the more stable it will get.</p>
|
|
|
269
|
|
|
270 <p>Suggestions are always welcome. If there is a feature that you
|
|
|
271 would like to have in MasqMail, contact me, and I will think about
|
|
|
272 it. You are also welcome to send patches, but at this stage of
|
|
|
273 development there will be no CVS access.</p>
|
|
|
274
|
|
|
275 <p>If you are using it and are happy with, you can also write that to
|
|
|
276 me. To make <em>me</em> happy.</p>
|
|
|
277
|
|
|
278 <p>If you are not happy with it, you can keep that for
|
|
|
279 yourself. Before you send some flame, please read these pages very
|
|
|
280 carefully again.</p>
