modes are now enforced exclusive Other MTAs (exim, postfix) are more relaxing, but as combinations of exclusive modes are senseless we behave more obvious if we fail early. This makes understanding the behavior easier too.

meillo@215 1 Frequently Asked Questions
meillo@215 2 ==========================
meillo@215 3
meillo@215 4 Some of these questions were never asked, but I thought they will
meillo@215 5 be some time. Some were asked.
meillo@215 6
meillo@215 7
meillo@215 8 When do I need MasqMail?
meillo@215 9 ------------------------
meillo@215 10 You do not *need* it. But it makes sending mails via a dialup
meillo@215 11 connection a lot easier.
meillo@215 12
meillo@215 13 It is useful if you dial to the internet from time to time via a
meillo@215 14 modem and connect to different providers, each one with a
meillo@215 15 different configuration. Other MTAs are not flexible enough if you
meillo@215 16 have to send mails via different mail servers for each provider.
meillo@215 17 With MasqMail you can configure a different one for each provider
meillo@215 18 and even set your return addresses differently.
meillo@215 19
meillo@215 20 It is also useful if you have a LAN with a gateway which is
meillo@215 21 connected to the internet via a modem because you can rewrite your
meillo@215 22 address depending on whether the recipients are *inside* or
meillo@215 23 *outside* your LAN. So responses and delivery failures on your LAN
meillo@215 24 will be sent to you without leaving it, while those outside will
meillo@215 25 be delivered to your address outside. (But it does not yet send
meillo@215 26 delivery failures itself yet.)
meillo@215 27
meillo@215 28 MasqMail is also often used on notebooks.
meillo@215 29
meillo@215 30
meillo@215 31 When do I not need MasqMail?
meillo@215 32 ----------------------------
meillo@215 33 The use of MasqMail is *strongly* discouraged if you have a
meillo@215 34 permanent connection to the internet without a firewall. First
meillo@215 35 because it does not have the ability to block relaying (it relays
meillo@215 36 every mail) and second because there are no capabilities to
meillo@215 37 protect against SPAM. You will not take advantages of its features
meillo@215 38 anyway.
meillo@215 39
meillo@215 40
meillo@215 41 Is there a mailing list for MasqMail?
meillo@215 42 -------------------------------------
meillo@215 43 Yes, there is! See here.
meillo@215 44
meillo@215 45
meillo@215 46 After starting masmail, I get the following message: "could
meillo@215 47 not gain root privileges. Is the setuid bit set?"
meillo@215 48 -----------------------------------------------------------
meillo@215 49 Set the set-user-id-bit with chmod u+s /usr/sbin/masqmail.
meillo@215 50
meillo@215 51
meillo@215 52 After starting masmail, I get the following message: "bind:
meillo@215 53 (terminating): Address already in use"
meillo@215 54 -----------------------------------------------------------
meillo@215 55 This means that there is already a process listening on a port,
meillo@215 56 usually 25. You either have another MTA running in background
meillo@215 57 (sendmail, exim, etc...) or another instance of masqmail.
meillo@215 58
meillo@215 59 It may also mean that the ports you configured MM to listen to
meillo@215 60 (with 'listen_addresses') are on the same IP address, eg. you may
meillo@215 61 have set your hostname to 127.0.0.1 and try to listen on localhost
meillo@215 62 and your host name. In this case either set your hostname to
meillo@215 63 another IP address or delete one of the conflicting entries.
meillo@215 64
meillo@215 65
meillo@215 66 My friends told me that they do not see my full name in their
meillo@215 67 inbox, although it is configured in my mail client.
meillo@215 68 -------------------------------------------------------------
meillo@215 69 You probably used the map_h_from_addresses feature in the route
meillo@215 70 configuration and forgot to set your real name. The syntax is:
meillo@215 71
meillo@215 72 map_h_from_addresses = "charlie:Charlie Miller <cmiller@foo.com>";
meillo@215 73
meillo@215 74 Do not forget the Charlie Miller.
meillo@215 75
meillo@215 76
meillo@215 77 With connection method file, I get the following message in
meillo@215 78 the log file: "Could not open /tmp/connect_route: Permission
meillo@215 79 denied".
meillo@215 80 ------------------------------------------------------------
meillo@215 81 In your ip-up script, you have to set read permission to the user
meillo@215 82 masqmail runs as. After you write the file with the connection
meillo@215 83 name, set read permission to all with chmod ugo+r file.
meillo@215 84
meillo@215 85
meillo@215 86 With connection method file, I get the following message in
meillo@215 87 the log file: "route with name name not found.".
meillo@215 88 -----------------------------------------------------------
meillo@215 89 Check whether the name in the file is really identical to name you
meillo@215 90 gave to the route configuration (case sensitive!).
meillo@215 91
meillo@215 92
meillo@215 93 I found a bug.
meillo@215 94 --------------
meillo@215 95 Make sure you are using the newest version, in case of doubt
meillo@215 96 search it in freshmeat. If you do, tell me. See also the section
meillo@215 97 bugs on the main page.
meillo@215 98
meillo@215 99
meillo@215 100 I think I found a bug, but I am not sure whether I configured
meillo@215 101 MasqMail incorrectly.
meillo@215 102 -------------------------------------------------------------
meillo@215 103 Don't care. Tell me. Or write to the mailing list.
