meillo@59 5 Installation instructions
meillo@59 6 -------------------------
meillo@59 7
meillo@165 8 To compile masqmail you need glib (>= 1.2) (http://www.gtk.org). Your
meillo@181 9 distribution probably provides it. Glib-2.0 works out of the box, for
meillo@181 10 glib-1.2, you need to adjust configure.ac. See the comment in there.
meillo@0 11
meillo@165 12 You need a user and a group for masqmail to run. If
meillo@165 13
meillo@165 14 grep '^mail:' /etc/passwd
meillo@358 15 grep '^mail:' /etc/group
meillo@165 16
meillo@358 17 shows that the user `mail' and the group `mail' exist, it's probably
meillo@358 18 best to use these. If they don't exist, create them:
meillo@0 19
meillo@358 20 groupadd -g 12 mail
meillo@358 21 useradd -u 8 -g mail -d /nonexistent -s /bin/false -c "masqmail MTA" mail
meillo@0 22
meillo@358 23 The 8 and 12 are common uid/gid for the user and group `mail', but you can
meillo@358 24 use any (not yet used) number you like, preferably one lower than 100.
meillo@358 25 If you use other names than `mail' and `mail', you need to use the
meillo@358 26 configure options described below.
meillo@165 27
meillo@0 28
meillo@174 29 Compiling is a matter of the usual procedure. In the source directory,
meillo@59 30 after unpacking do:
meillo@0 31
meillo@59 32 ./configure
meillo@59 33 make
meillo@59 34 make install
meillo@0 35
meillo@0 36
meillo@0 37
meillo@59 38 Additional options for configure
meillo@59 39 --------------------------------
meillo@0 40
meillo@59 41 See the output of
meillo@0 42
meillo@59 43 ./configure -h
meillo@0 44
meillo@165 45 Here is a selection of the options with additional explanations:
meillo@0 46
meillo@165 47 --with-user=USER
meillo@165 48 sets the user as which masqmail will run. Default is 'mail'. USER has
meillo@165 49 to exist before you 'make install'.
meillo@0 50
meillo@165 51 --with-group=GROUP
meillo@358 52 sets the group as which masqmail will run. Default is 'mail'. GROUP
meillo@165 53 has to exist before you 'make install'.
meillo@0 54
meillo@0 55
meillo@165 56 --with-logdir=LOGDIR
meillo@165 57 sets the directory where masqmail stores its log files. It will be
meillo@165 58 created if it does not exist. Default is /var/log/masqmail/.
meillo@0 59
meillo@165 60 --with-spooldir=SPOOLDIR
meillo@165 61 sets the directory where masqmail stores its spool files. It will be
meillo@165 62 created if it does not exist. Default is /var/spool/masqmail/.
meillo@0 63
meillo@165 64 --with-confdir=CONFDIR
meillo@165 65 sets the default configuration directory to CONFDIR, in case you
meillo@165 66 prefer another location than /etc/masqmail/.
meillo@0 67
meillo@0 68
meillo@165 69 --enable-auth
meillo@165 70 enables ESMTP AUTH support (disabled by default)
meillo@0 71
meillo@165 72 --enable-ident
meillo@175 73 enables RFC 1413 support. If you have the libident dynamic library
meillo@165 74 installed, this will be linked, otherwise it will be statically linked
meillo@360 75 using the sources included in the package. Ident support brings few
meillo@360 76 advantages. If mail is received from machines that run identd, the
meillo@360 77 Received headers and log messages include a user name too. Additionally
meillo@360 78 a user can remove queued mail if it had been sent by himself from another
meillo@360 79 machine running identd. In any case: You cannot trust the ident
meillo@360 80 information more than you trust the specific remote machine.
meillo@0 81
meillo@165 82 --disable-resolver
meillo@175 83 disables resolver support. Without the resolver functions, masqmail
meillo@165 84 uses only gethostbyname() to resolve DNS names, and you cannot send
meillo@165 85 mail without a smart host. Not recommended.
meillo@0 86
meillo@165 87
meillo@165 88 --with-libcryto
meillo@165 89 instead of using the md5 and hmac functions within the package, link
meillo@192 90 dynamically with libcrypto. This applies only if you have SMTP AUTH
meillo@192 91 enabled. Only makes sense if your resources are limited and you have
meillo@192 92 libcrypto installed. Untested.
meillo@165 93
meillo@0 94
meillo@165 95 --disable-debug
meillo@175 96 disables debugging; setting it on the command line or in the
meillo@175 97 configuration has no effect. Strongly discouraged, since you miss
meillo@175 98 valuable information if something goes wrong.

meillo@165 102 Checking the installation
meillo@165 103 -------------------------
meillo@0 104
meillo@0 105 Check that 'make install' worked correctly. The following command:
meillo@0 106
meillo@195 107 ls -ld /usr/local/sbin/masqmail /etc/masqmail /var/log/masqmail/ \
meillo@174 108 /var/run/masqmail /var/spool/masqmail/ /var/spool/masqmail/*
meillo@0 109
meillo@0 110 should give output similar to
meillo@0 111
meillo@165 112 -rwsr-xr-x 1 root root 399356 May 10 12:34 /usr/local/sbin/masqmail
meillo@59 113 drwxr-xr-x 2 root root 4096 May 10 12:34 /etc/masqmail
meillo@358 114 drwxr-xr-x 2 mail mail 4096 May 10 12:34 /var/log/masqmail
meillo@358 115 drwxr-xr-x 2 mail mail 4096 May 10 12:34 /var/run/masqmail
meillo@358 116 drwxr-xr-x 5 mail mail 4096 May 10 12:34 /var/spool/masqmail
meillo@358 117 drwxr-xr-x 2 mail mail 4096 May 10 12:34 /var/spool/masqmail/input
meillo@358 118 drwxr-xr-x 2 mail mail 4096 May 10 12:34 /var/spool/masqmail/lock
meillo@0 119
meillo@165 120 Important are the set-user-id bit for /usr/local/sbin/masqmail and
meillo@165 121 the permissions of all files.

meillo@165 125 Making masqmail the default
meillo@165 126 ---------------------------
meillo@0 127
meillo@165 128 `sendmail' is the de-facto standard name of the system's MTA, no
meillo@165 129 matter which MTA actually runs. If you want to make masqmail the
meillo@185 130 system's MTA (i.e. replace sendmail, postfix, etc), make two symbolic
meillo@185 131 links:
meillo@0 132
meillo@165 133 ln -s /usr/local/sbin/masqmail /usr/lib/sendmail
meillo@185 134 ln -s /usr/local/sbin/masqmail /usr/sbin/sendmail
meillo@0 135
meillo@165 136 Now every mailer that used to call sendmail will now call masqmail.
meillo@165 137 If you already had an MTA installed and running, you can kill it and
meillo@165 138 start masqmail. Probably with:
meillo@59 139
meillo@165 140 /etc/init.d/sendmail restart
meillo@59 141
meillo@165 142 If this doesn't work as expected, you might need to add a special init
meillo@165 143 script for masqmail. Currently none is distributed with masqmail.
meillo@165 144 (Hopefully this will change soon.) Please ask on the mailing list for
meillo@165 145 help.
meillo@59 146
meillo@165 147 You can also directly start masqmail as daemon with:
meillo@59 148
meillo@165 149 /usr/local/sbin/masqmail -bd -q30m
meillo@59 150
meillo@59 151
meillo@59 152
meillo@165 153 Basic Configuration
meillo@165 154 -------------------
meillo@59 155
meillo@165 156 The only thing you must configure in order to use masqmail is the
meillo@165 157 hostname. It's the name under which masqmail operates. In most cases
meillo@165 158 it is the same as the machine's name, but it can be different.
meillo@59 159
meillo@227 160 The script `admin/guess-hostname' tries to print the hostname of
meillo@165 161 your machine. The first output line is probably the best choice.
meillo@59 162
meillo@165 163 Create a minimal config with:
meillo@59 164
meillo@165 165 echo "host_name = HOSTNAME" >/etc/masqmail/masqmail.conf
meillo@59 166
meillo@165 167 (Substitute `HOSTNAME' with the real value, of course.)
meillo@59 168
meillo@165 169 Such a setup (i.e. the default one) does:
meillo@165 170 - deliver mail locally
meillo@206 171 - accept mail on stdin (plain text)
meillo@206 172 - accept mail on stdin (SMTP) (if started with -bs)
meillo@206 173 - accept mail on the local port 25 (SMTP) (if started with -bd)
meillo@185 174
meillo@165 175 It does not
meillo@185 176 - transfer mail to other machines
meillo@165 177 - accept mail from outside your machine
meillo@59 178
meillo@59 179
meillo@165 180 For more elaborate setups, have a look at docs/*setup and
meillo@165 181 docs/INSTALL*. You can also take the example configuration files in
meillo@165 182 examples/ as basis for your own. Take the man pages masqmail.conf(5)
meillo@165 183 and masqmail.route(5) for reference.
meillo@92 184
meillo@165 185 All configuration files should go into /etc/masqmail.
