5 Installation instructions
6 -------------------------
8 To compile masqmail you need glib (>= 1.2) (http://www.gtk.org). Your
9 distribution probably provides it. Glib-2.0 works out of the box, for
10 glib-1.2, you need to adjust configure.ac. See the comment in there.
12 You need a user and a group for masqmail to run. If
14 grep '^mail:' /etc/passwd
15 grep '^mail:' /etc/group
17 shows that the user `mail' and the group `mail' exist, it's probably
18 best to use these. If they don't exist, create them:
20 groupadd -g 12 mail
21 useradd -u 8 -g mail -d /nonexistent -s /bin/false -c "masqmail MTA" mail
23 The 8 and 12 are common uid/gid for the user and group `mail', but you can
24 use any (not yet used) number you like, preferably one lower than 100.
25 If you use other names than `mail' and `mail', you need to use the
26 configure options described below.
29 Compiling is a matter of the usual procedure. In the source directory,
30 after unpacking do:
32 ./configure
33 make
34 make install
38 Additional options for configure
39 --------------------------------
41 See the output of
43 ./configure -h
45 Here is a selection of the options with additional explanations:
47 --with-user=USER
48 sets the user as which masqmail will run. Default is 'mail'. USER has
49 to exist before you 'make install'.
51 --with-group=GROUP
52 sets the group as which masqmail will run. Default is 'mail'. GROUP
53 has to exist before you 'make install'.
56 --with-logdir=LOGDIR
57 sets the directory where masqmail stores its log files. It will be
58 created if it does not exist. Default is /var/log/masqmail/.
60 --with-spooldir=SPOOLDIR
61 sets the directory where masqmail stores its spool files. It will be
62 created if it does not exist. Default is /var/spool/masqmail/.
64 --with-confdir=CONFDIR
65 sets the default configuration directory to CONFDIR, in case you
66 prefer another location than /etc/masqmail/.
69 --enable-auth
70 enables ESMTP AUTH support (disabled by default)
72 --enable-ident
73 enables RFC 1413 support. If you have the libident dynamic library
74 installed, this will be linked, otherwise it will be statically linked
75 using the sources included in the package. Ident support brings few
76 advantages. If mail is received from machines that run identd, the
77 Received headers and log messages include a user name too. Additionally
78 a user can remove queued mail if it had been sent by himself from another
79 machine running identd. In any case: You cannot trust the ident
80 information more than you trust the specific remote machine.
82 --disable-resolver
83 disables resolver support. Without the resolver functions, masqmail
84 uses only gethostbyname() to resolve DNS names, and you cannot send
85 mail without a smart host. Not recommended.
88 --with-libcryto
89 instead of using the md5 and hmac functions within the package, link
90 dynamically with libcrypto. This applies only if you have SMTP AUTH
91 enabled. Only makes sense if your resources are limited and you have
92 libcrypto installed. Untested.
95 --disable-debug
96 disables debugging; setting it on the command line or in the
97 configuration has no effect. Strongly discouraged, since you miss
98 valuable information if something goes wrong.
102 Checking the installation
103 -------------------------
105 Check that 'make install' worked correctly. The following command:
107 ls -ld /usr/local/sbin/masqmail /etc/masqmail /var/log/masqmail/ \
108 /var/run/masqmail /var/spool/masqmail/ /var/spool/masqmail/*
110 should give output similar to
112 -rwsr-xr-x 1 root root 399356 May 10 12:34 /usr/local/sbin/masqmail
113 drwxr-xr-x 2 root root 4096 May 10 12:34 /etc/masqmail
114 drwxr-xr-x 2 mail mail 4096 May 10 12:34 /var/log/masqmail
115 drwxr-xr-x 2 mail mail 4096 May 10 12:34 /var/run/masqmail
116 drwxr-xr-x 5 mail mail 4096 May 10 12:34 /var/spool/masqmail
117 drwxr-xr-x 2 mail mail 4096 May 10 12:34 /var/spool/masqmail/input
118 drwxr-xr-x 2 mail mail 4096 May 10 12:34 /var/spool/masqmail/lock
120 Important are the set-user-id bit for /usr/local/sbin/masqmail and
121 the permissions of all files.
125 Making masqmail the default
126 ---------------------------
128 `sendmail' is the de-facto standard name of the system's MTA, no
129 matter which MTA actually runs. If you want to make masqmail the
130 system's MTA (i.e. replace sendmail, postfix, etc), make two symbolic
131 links:
133 ln -s /usr/local/sbin/masqmail /usr/lib/sendmail
134 ln -s /usr/local/sbin/masqmail /usr/sbin/sendmail
136 Now every mailer that used to call sendmail will now call masqmail.
137 If you already had an MTA installed and running, you can kill it and
138 start masqmail. Probably with:
140 /etc/init.d/sendmail restart
142 If this doesn't work as expected, you might need to add a special init
143 script for masqmail. Currently none is distributed with masqmail.
144 (Hopefully this will change soon.) Please ask on the mailing list for
145 help.
147 You can also directly start masqmail as daemon with:
149 /usr/local/sbin/masqmail -bd -q30m
153 Basic Configuration
154 -------------------
156 The only thing you must configure in order to use masqmail is the
157 hostname. It's the name under which masqmail operates. In most cases
158 it is the same as the machine's name, but it can be different.
160 The script `admin/guess-hostname' tries to print the hostname of
161 your machine. The first output line is probably the best choice.
163 Create a minimal config with:
165 echo "host_name = HOSTNAME" >/etc/masqmail/masqmail.conf
167 (Substitute `HOSTNAME' with the real value, of course.)
169 Such a setup (i.e. the default one) does:
170 - deliver mail locally
171 - accept mail on stdin (plain text)
172 - accept mail on stdin (SMTP) (if started with -bs)
173 - accept mail on the local port 25 (SMTP) (if started with -bd)
175 It does not
176 - transfer mail to other machines
177 - accept mail from outside your machine
180 For more elaborate setups, have a look at docs/*setup and
181 docs/INSTALL*. You can also take the example configuration files in
182 examples/ as basis for your own. Take the man pages masqmail.conf(5)
183 and masqmail.route(5) for reference.
185 All configuration files should go into /etc/masqmail.
