4 Some of these questions were never asked, but I thought they will
|
|
|

8 When do I need MasqMail?
|
|
|
9 ------------------------
|
|
|
10 You do not *need* it. But it makes sending mails via a dialup
|
|
|
11 connection a lot easier.
|
|
|
12
|
|
|
13 It is useful if you dial to the internet from time to time via a
|
|
|
14 modem and connect to different providers, each one with a
|
|
|
15 different configuration. Other MTAs are not flexible enough if you
|
|
|
16 have to send mails via different mail servers for each provider.
|
|
|
17 With MasqMail you can configure a different one for each provider
|
|
|
18 and even set your return addresses differently.
|
|
|
19
|
|
|
20 It is also useful if you have a LAN with a gateway which is
|
|
|
21 connected to the internet via a modem because you can rewrite your
|
|
|
22 address depending on whether the recipients are *inside* or
|
|
|
23 *outside* your LAN. So responses and delivery failures on your LAN
|
|
|
24 will be sent to you without leaving it, while those outside will
|
|
|
25 be delivered to your address outside. (But it does not yet send
|
|
|
26 delivery failures itself yet.)
|
|
|
27
|
|
|
28 MasqMail is also often used on notebooks.

|
31 When do I not need MasqMail?
|
|
|
32 ----------------------------
|
|
|
33 The use of MasqMail is *strongly* discouraged if you have a
|
|
|
34 permanent connection to the internet without a firewall. First
|
|
|
35 because it does not have the ability to block relaying (it relays
|
|
|
36 every mail) and second because there are no capabilities to
|
|
|
37 protect against SPAM. You will not take advantages of its features
|
|
|
38 anyway.
|
|
|
39
|
|
|
40
|
|
|
41 Is there a mailing list for MasqMail?
|
|
|
42 -------------------------------------
|
|
|
43 Yes, there is! See here.
|
|
|
44
|
|
|
45
|
|
|
46 After starting masmail, I get the following message: "could
|
|
|
47 not gain root privileges. Is the setuid bit set?"
|
|
|
48 -----------------------------------------------------------
|
|
|
49 Set the set-user-id-bit with chmod u+s /usr/sbin/masqmail.
|
|
|
50
|
|
|
51
|
|
|
52 After starting masmail, I get the following message: "bind:
|
|
|
53 (terminating): Address already in use"
|
|
|
54 -----------------------------------------------------------
|
|
|
55 This means that there is already a process listening on a port,
|
|
|
56 usually 25. You either have another MTA running in background
|
|
|
57 (sendmail, exim, etc...) or another instance of masqmail.
|
|
|
58
|
|
|
59 It may also mean that the ports you configured MM to listen to
|
|
|
60 (with 'listen_addresses') are on the same IP address, eg. you may
|
|
|
61 have set your hostname to 127.0.0.1 and try to listen on localhost
|
|
|
62 and your host name. In this case either set your hostname to
|
|
|
63 another IP address or delete one of the conflicting entries.
|
|
|
64
|
|
|
65
|
|
|
66 My friends told me that they do not see my full name in their
|
|
|
67 inbox, although it is configured in my mail client.
|
|
|
68 -------------------------------------------------------------
|
|
|
69 You probably used the map_h_from_addresses feature in the route
|
|
|
70 configuration and forgot to set your real name. The syntax is:
|
|
|
71
|
|
|
72 map_h_from_addresses = "charlie:Charlie Miller <cmiller@foo.com>";
|
|
|
73
|
|
|
74 Do not forget the Charlie Miller.
|
|
|
75
|
|
|
76
|
|
|
77 With connection method file, I get the following message in
|
|
|
78 the log file: "Could not open /tmp/connect_route: Permission
|
|
|
79 denied".
|
|
|
80 ------------------------------------------------------------
|
|
|
81 In your ip-up script, you have to set read permission to the user
|
|
|
82 masqmail runs as. After you write the file with the connection
|
|
|
83 name, set read permission to all with chmod ugo+r file.
|
|
|
84
|
|
|
85
|
|
|
86 With connection method file, I get the following message in
|
|
|
87 the log file: "route with name name not found.".
|
|
|
88 -----------------------------------------------------------
|
|
|
89 Check whether the name in the file is really identical to name you
|
|
|
90 gave to the route configuration (case sensitive!).
|
|
|
91
|
|
|
92
|
|
|
93 I found a bug.
|
|
|
94 --------------
|
|
|
95 Make sure you are using the newest version, in case of doubt
|
|
|
96 search it in freshmeat. If you do, tell me. See also the section
|
|
|
97 bugs on the main page.
|
|
|
98
|
|
|
99
|
|
|
100 I think I found a bug, but I am not sure whether I configured
|
|
|
101 MasqMail incorrectly.
|
|
|
102 -------------------------------------------------------------
|
|
|
103 Don't care. Tell me. Or write to the mailing list.
