28 Some of these questions were never asked, but I thought they will be

29 some time. Some <em>were</em> asked.

66 <a name="1_0"> <h4>1.0: When do I need MasqMail?</h4></a>
|
|
|
67
|
|
|
68 <p> You do not <em>need</em> it. But it makes sending mails via a
|
|
|
69 dialup connection a lot easier.</p>
|
|
|
70
|
|
|
71 <p>It is useful if you dial to the internet from time to time via a
|
|
|
72 modem and connect to different providers, each one with a different
|
|
|
73 configuration. Other MTAs are not flexible enough if you have to send
|
|
|
74 mails via different mail servers for each provider. With MasqMail you
|
|
|
75 can configure a different one for each provider and even set your
|
|
|
76 return addresses differently.</p>
|
|
|
77
|
|
|
78 <p>It is also useful if you have a LAN with a gateway which is
|
|
|
79 connected to the internet via a modem because you can rewrite your
|
|
|
80 address depending on whether the recipients are <em>inside</em> or
|
|
|
81 <em>outside</em> your LAN. So responses and delivery failures on your
|
|
|
82 LAN will be sent to you without leaving it, while those outside will
|
|
|
83 be delivered to your address outside. (But it does not yet send
|
|
|
84 delivery failures itself yet.)</p>
|
|
|
85
|
|
|
86 <p>MasqMail is also often used on notebooks.</p>
|
|
|
87
|
|
|
88 <a name="1_1"><h4>1.1: When do I <em>not</em> need MasqMail?</h4></a>
|
|
|
89
|
|
|
90 <p>The use of MasqMail is <em>strongly</em> discouraged if you have a
|
|
|
91 permanent connection to the internet without a firewall. First because
|
|
|
92 it does not have the ability to block relaying (it relays every mail)
|
|
|
93 and second because there are no capabilities to protect against
|
|
|
94 SPAM. You will not take advantages of its features anyway.</p>
|
|
|
95
|
|
|
96 <a name="1_2"><h4>1.2: Can I retrieve mail with MasqMail?</h4></a>
|
|
|
97
|
|
|
98 <p>Yes, for version >= 0.1.0 you can retrieve mail via the POP3 and
|
|
|
99 APOP protocol from single drop mailboxes (in case you do not know
|
|
|
100 about single/mutidrop, you probaby use single drop mailboxes).</p>
|
|
|
101
|
|
|
102 <p>You can also use fetchmail or other pop/imap clients to feed
|
|
|
103 it.</p>
|
|
|
104
|
|
|
105 <a name="1_3"><h4>1.3: Is there a mailing list for MasqMail?</h4></a>
|
|
|
106
|
|
|
107 <p>Yes, there is! See <a href="http://www.innominate.org/mailman/listinfo/masqmail">here</a>.</p>
|
|
|
108
|
|
|
109 <a name="2_0"><h4>2.0: After starting masmail, I get the following
|
|
|
110 message: "could not gain root privileges. Is the setuid bit set?"</h4></a>
|
|
|
111
|
|
|
112 <p>Set the set-user-id-bit with chmod u+s /usr/sbin/masqmail.</p>
|
|
|
113
|
|
|
114 <a name="2_1"><h4>2.1: After starting masmail, I get the following
|
|
|
115 message: "bind: (terminating): Address already in use"</h4></a>
|
|
|
116
|
|
|
117 <p>This means that there is already a process listening on a port,
|
|
|
118 usually 25. You either have another MTA running in background
|
|
|
119 (sendmail, exim, etc...) or another instance of masqmail.</p>
|
|
|
120
|
|
|
121 <p>It may also mean that the ports you configured MM to listen to
|
|
|
122 (with 'listen_addresses') are on the same IP address, eg. you may have
|
|
|
123 set your hostname to 127.0.0.1 and try to listen on localhost and your
|
|
|
124 host name. In this case either set your hostname to another IP address
|
|
|
125 or delete one of the conflicting entries.</p>

127 <a name="3_0"><h4>3.0: My friends told me that they do not see my full
|
|
|
128 name in their inbox, although it is configured in my mail
|
|
|
129 client.</h4></a>
|
|
|
130
|
|
|
131 <p>You probably used the <b>map_h_from_addresses</b> feature in the
|
|
|
132 route configuration and forgot to set your real name. The syntax
|
|
|
133 is:</p>
|
|
|
134
|
|
|
135 <pre>
|
|
|
136 map_h_from_addresses = "charlie:Charlie Miller <cmiller@foo.com>";
|
|
|
137 </pre>
|
|
|
138
|
|
|
139 <p>Do not forget the <em>Charlie Miller</em>.</p>
|
|
|
140
|
|
|
141 <a name="4_0"><h4>4.0: With connection method <em>file</em>, I get the
|
|
|
142 following message in the log file: "Could not open /tmp/connect_route:
|
|
|
143 Permission denied".</h4></a>
|
|
|
144
|
|
|
145 <p>In your ip-up script, you have to set read permission to the user
|
|
|
146 masqmail runs as. After you write the file with the connection name,
|
|
|
147 set read permission to all with chmod ugo+r <em>file</em>.

|
|
|
152
|
|
|
153 <p>Check whether the name in the file is really identical to name you
|
|
|
154 gave to the route configuration (case sensitive!). Maybe there is a
|
|
|
155 linefeed after the name in the file. Write it with echo -n.</p>
