2 | # The Exim mail transport agent # | |
3 | ################################################## | |
4 | ||
5 | # This is the template for Exim's main build-time configuration file. It | |
6 | # contains settings that are independent of any operating system. These are | |
7 | # things that are mostly sysadmin choices. The items below are divided into | |
8 | # those you must specify, those you probably want to specify, those you might | |
9 | # often want to specify, and those that you almost never need to mention. | |
10 | ||
11 | # Edit this file and save the result to a file called Local/Makefile within the | |
12 | # Exim distribution directory before running the "make" command. | |
13 | ||
14 | # Things that depend on the operating system have default settings in | |
15 | # OS/Makefile-Default, but these are overridden for some OS by files called | |
16 | # called OS/Makefile-<osname>. You can further override these by creating files | |
17 | # called Local/Makefile-<osname>, where "<osname>" stands for the name of your | |
18 | # operating system - look at the names in the OS directory to see which names | |
19 | # are recognized. | |
20 | ||
21 | # However, if you are building Exim for a single OS only, you don't need to | |
22 | # worry about setting up Local/Makefile-<osname>. Any build-time configuration | |
23 | # settings you require can in fact be placed in the one file called | |
24 | # Local/Makefile. It is only if you are building for several OS from the same | |
25 | # source files that you need to worry about splitting off your own OS-dependent | |
26 | # settings into separate files. (There's more explanation about how this all | |
27 | # works in the toplevel README file, under "Modifying the building process", as | |
28 | # well as in the Exim specification.) | |
29 | ||
30 | # One OS-specific thing that may need to be changed is the command for running | |
31 | # the C compiler; the overall default is gcc, but some OS Makefiles specify cc. | |
32 | # You can override anything that is set by putting CC=whatever in your | |
33 | # Local/Makefile. | |
34 | ||
35 | # NOTE: You should never need to edit any of the distributed Makefiles; all | |
36 | # overriding can be done in your Local/Makefile(s). This will make it easier | |
37 | # for you when the next release comes along. | |
38 | ||
39 | # The location of the X11 libraries is something else that is quite variable | |
40 | # even between different versions of the same operating system (and indeed | |
41 | # there are different versions of X11 as well, of course). The four settings | |
42 | # concerned here are X11, XINCLUDE, XLFLAGS (linking flags) and X11_LD_LIB | |
43 | # (dynamic run-time library). You need not worry about X11 unless you want to | |
44 | # compile the Exim monitor utility. Exim itself does not use X11. | |
45 | ||
46 | # Another area of variability between systems is the type and location of the | |
47 | # DBM library package. Exim has support for ndbm, gdbm, tdb, and Berkeley DB. | |
48 | # By default the code assumes ndbm; this often works with gdbm or DB, provided | |
49 | # they are correctly installed, via their compatibility interfaces. However, | |
50 | # Exim can also be configured to use the native calls for Berkeley DB (obsolete | |
51 | # versions 1.85, 2.x, 3.x, or the current 4.x version) and also for gdbm. | |
52 | ||
53 | # For some operating systems, a default DBM library (other than ndbm) is | |
54 | # selected by a setting in the OS-specific Makefile. Most modern OS now have | |
55 | # a DBM library installed as standard, and in many cases this will be selected | |
56 | # for you by the OS-specific configuration. If Exim compiles without any | |
57 | # problems, you probably do not have to worry about the DBM library. If you | |
58 | # do want or need to change it, you should first read the discussion in the | |
59 | # file doc/dbm.discuss.txt, which also contains instructions for testing Exim's | |
60 | # interface to the DBM library. | |
61 | ||
62 | # In Local/Makefiles blank lines and lines starting with # are ignored. It is | |
63 | # also permitted to use the # character to add a comment to a setting, for | |
64 | # example | |
65 | # | |
66 | # EXIM_GID=42 # the "mail" group | |
67 | # | |
68 | # However, with some versions of "make" this works only if there is no white | |
69 | # space between the end of the setting and the #, so perhaps it is best | |
70 | # avoided. A consequence of this facility is that it is not possible to have | |
71 | # the # character present in any setting, but I can't think of any cases where | |
72 | # this would be wanted. | |

81 | # Exim will not build unless you specify BIN_DIRECTORY, CONFIGURE_FILE, and | |
82 | # EXIM_USER. You also need EXIM_GROUP if EXIM_USER specifies a uid by number. | |
83 | ||
84 | # If you don't specify SPOOL_DIRECTORY, Exim won't fail to build. However, it | |
85 | # really is a very good idea to specify it here rather than at run time. This | |
86 | # is particularly true if you let the logs go to their default location in the | |
87 | # spool directory, because it means that the location of the logs is known | |
88 | # before Exim has read the run time configuration file. | |
89 | ||
90 | #------------------------------------------------------------------------------ | |
91 | # BIN_DIRECTORY defines where the exim binary will be installed by "make | |
92 | # install". The path is also used internally by Exim when it needs to re-invoke | |
93 | # itself, either to send an error message, or to recover root privilege. Exim's | |
94 | # utility binaries and scripts are also installed in this directory. There is | |
95 | # no "standard" place for the binary directory. Some people like to keep all | |
96 | # the Exim files under one directory such as /usr/exim; others just let the | |
97 | # Exim binaries go into an existing directory such as /usr/sbin or | |
98 | # /usr/local/sbin. The installation script will try to create this directory, | |
99 | # and any superior directories, if they do not exist. | |
100 | ||
101 | BIN_DIRECTORY=/usr/exim/bin | |
102 | ||
103 | ||
104 | #------------------------------------------------------------------------------ | |
105 | # CONFIGURE_FILE defines where Exim's run time configuration file is to be | |
106 | # found. It is the complete pathname for the file, not just a directory. The | |
107 | # location of all other run time files and directories can be changed in the | |
108 | # run time configuration file. There is a lot of variety in the choice of | |
109 | # location in different OS, and in the preferences of different sysadmins. Some | |
110 | # common locations are in /etc or /etc/mail or /usr/local/etc or | |
111 | # /usr/local/etc/mail. Another possibility is to keep all the Exim files under | |
112 | # a single directory such as /usr/exim. Whatever you choose, the installation | |
113 | # script will try to make the directory and any superior directories if they | |
114 | # don't exist. It will also install a default runtime configuration if this | |
115 | # file does not exist. | |
116 | ||
117 | CONFIGURE_FILE=/usr/exim/configure | |
118 | ||
119 | # It is possible to specify a colon-separated list of files for CONFIGURE_FILE. | |
120 | # In this case, Exim will use the first of them that exists when it is run. | |
121 | # However, if a list is specified, the installation script no longer tries to | |
122 | # make superior directories or to install a default runtime configuration. | |
123 | ||
124 | ||
125 | #------------------------------------------------------------------------------ | |
126 | # The Exim binary must normally be setuid root, so that it starts executing as | |
127 | # root, but (depending on the options with which it is called) it does not | |
128 | # always need to retain the root privilege. These settings define the user and | |
129 | # group that is used for Exim processes when they no longer need to be root. In | |
130 | # particular, this applies when receiving messages and when doing remote | |
131 | # deliveries. (Local deliveries run as various non-root users, typically as the | |
10385c15 | 132 | # owner of a local mailbox.) Specifying these values as root is not supported. |

134 | EXIM_USER= | |
135 | ||
136 | # If you specify EXIM_USER as a name, this is looked up at build time, and the | |
137 | # uid number is built into the binary. However, you can specify that this | |
138 | # lookup is deferred until runtime. In this case, it is the name that is built | |
139 | # into the binary. You can do this by a setting of the form: | |
140 | ||
141 | # EXIM_USER=ref:exim | |
142 | ||
143 | # In other words, put "ref:" in front of the user name. If you set EXIM_USER | |
144 | # like this, any value specified for EXIM_GROUP is also passed "by reference". | |
145 | # Although this costs a bit of resource at runtime, it is convenient to use | |
146 | # this feature when building binaries that are to be run on multiple systems | |
147 | # where the name may refer to different uids. It also allows you to build Exim | |
148 | # on a system where there is no Exim user defined. | |
149 | ||
150 | # If the setting of EXIM_USER is numeric (e.g. EXIM_USER=42), there must | |
151 | # also be a setting of EXIM_GROUP. If, on the other hand, you use a name | |
152 | # for EXIM_USER (e.g. EXIM_USER=exim), you don't need to set EXIM_GROUP unless | |
153 | # you want to use a group other than the default group for the given user. | |
154 | ||
155 | # EXIM_GROUP= | |
156 | ||
157 | # Many sites define a user called "exim", with an appropriate default group, | |
158 | # and use | |
159 | # | |
160 | # EXIM_USER=exim | |
161 | # | |
162 | # while leaving EXIM_GROUP unspecified (commented out). | |

165 | #------------------------------------------------------------------------------ | |
166 | # SPOOL_DIRECTORY defines the directory where all the data for messages in | |
167 | # transit is kept. It is strongly recommended that you define it here, though | |
168 | # it is possible to leave this till the run time configuration. | |
169 | ||
170 | # Exim creates the spool directory if it does not exist. The owner and group | |
171 | # will be those defined by EXIM_USER and EXIM_GROUP, and this also applies to | |
172 | # all the files and directories that are created in the spool directory. | |
173 | ||
174 | # Almost all installations choose this: | |

667 | # When Exim is decoding MIME "words" in header lines, most commonly for use | |

676 | # character set on your host is something other than ISO-8859-1, you might | |
677 | # like to specify a different default here. This value can be overridden in | |
678 | # the runtime configuration, and it can also be overridden in individual filter | |
679 | # files. | |
680 | # | |
681 | # IMPORTANT NOTE: The iconv() function is needed for character code | |
682 | # conversions. Please see the next item... | |
683 | ||
684 | ||
685 | #------------------------------------------------------------------------------ | |
686 | # Character code conversions are possible only if the iconv() function is | |
687 | # installed on your operating system. There are two places in Exim where this | |
688 | # is relevant: (a) The $header_xxx expansion (see the previous item), and (b) | |
689 | # the Sieve filter support. For those OS where iconv() is known to be installed | |
690 | # as standard, the file in OS/Makefile-xxxx contains | |
691 | # | |
692 | # HAVE_ICONV=yes | |
693 | # | |
694 | # If you are not using one of those systems, but have installed iconv(), you | |
695 | # need to uncomment that line above. In some cases, you may find that iconv() | |
696 | # and its header file are not in the default places. You might need to use | |
697 | # something like this: | |
698 | # | |
699 | # HAVE_ICONV=yes | |
700 | # CFLAGS=-O -I/usr/local/include | |
701 | # EXTRALIBS_EXIM=-L/usr/local/lib -liconv | |
702 | # | |
703 | # but of course there may need to be other things in CFLAGS and EXTRALIBS_EXIM | |
704 | # as well. | |
863bd541 PP |
705 | # |
706 | # nb: FreeBSD as of 4.89 defines LIBICONV_PLUG to pick up the system iconv | |
707 | # more reliably. If you explicitly want the libiconv Port then as well | |
708 | # as adding -liconv you'll want to unset LIBICONV_PLUG. If you actually need | |
709 | # this, let us know, but for now the Exim Maintainers are assuming that this | |
710 | # is uncommon and so you'll need to edit OS/os.h-FreeBSD yourself to remove | |
711 | # the define. | |

715 | # The passwords for user accounts are normally encrypted with the crypt() | |
716 | # function. Comparisons with encrypted passwords can be done using Exim's | |
717 | # "crypteq" expansion operator. (This is commonly used as part of the | |
718 | # configuration of an authenticator for use with SMTP AUTH.) At least one | |
719 | # operating system has an extended function called crypt16(), which uses up to | |
720 | # 16 characters of a password (the normal crypt() uses only the first 8). Exim | |
96c065cb | 721 | # supports the use of crypt16() as well as crypt() but note the warning below. |
059ec3d9 PH |
722 | |
723 | # You can always indicate a crypt16-encrypted password by preceding it with | |
724 | # "{crypt16}". If you want the default handling (without any preceding | |
725 | # indicator) to use crypt16(), uncomment the following line: | |
726 | ||
727 | # DEFAULT_CRYPT=crypt16 | |
728 | ||
729 | # If you do that, you can still access the basic crypt() function by preceding | |
730 | # an encrypted password with "{crypt}". For more details, see the description | |
731 | # of the "crypteq" condition in the manual chapter on string expansions. | |
732 | ||
96c065cb PH |
733 | # Some operating systems do not include a crypt16() function, so Exim has one |
734 | # of its own, which it uses unless HAVE_CRYPT16 is defined. Normally, that will | |
735 | # be set in an OS-specific Makefile for the OS that have such a function, so | |
736 | # you should not need to bother with it. | |
737 | ||
738 | # *** WARNING *** WARNING *** WARNING *** WARNING *** WARNING *** | |
739 | # It turns out that the above is not entirely accurate. As well as crypt16() | |
740 | # there is a function called bigcrypt() that some operating systems have. This | |
741 | # may or may not use the same algorithm, and both of them may be different to | |
742 | # Exim's built-in crypt16() that is used unless HAVE_CRYPT16 is defined. | |
743 | # | |
744 | # However, since there is now a move away from the traditional crypt() | |
745 | # functions towards using SHA1 and other algorithms, tidying up this area of | |
746 | # Exim is seen as very low priority. In practice, if you need to, you can | |
747 | # define DEFAULT_CRYPT to the name of any function that has the same interface | |

822 | # The default distribution of Exim contains only the plain text form of the | |
823 | # documentation. Other forms are available separately. If you want to install | |
824 | # the documentation in "info" format, first fetch the Texinfo documentation | |
825 | # sources from the ftp directory and unpack them, which should create files | |
826 | # with the extension "texinfo" in the doc directory. You may find that the | |
827 | # version number of the texinfo files is different to your Exim version number, | |
828 | # because the main documentation isn't updated as often as the code. For | |
65872480 | 829 | # example, if you have Exim version 4.43, the source tarball unpacks into a |
059ec3d9 PH |
830 | # directory called exim-4.43, but the texinfo tarball unpacks into exim-4.40. |
831 | # In this case, move the contents of exim-4.40/doc into exim-4.43/doc after you | |
832 | # have unpacked them. Then set INFO_DIRECTORY to the location of your info | |
833 | # directory. This varies from system to system, but is often /usr/share/info. | |
834 | # Once you have done this, "make install" will build the info files and | |
835 | # install them in the directory you have defined. | |

841 | # Exim log directory and files: Exim creates several log files inside a | |
842 | # single log directory. You can define the directory and the form of the | |
843 | # log file name here. If you do not set anything, Exim creates a directory | |
844 | # called "log" inside its spool directory (see SPOOL_DIRECTORY above) and uses | |
845 | # the filenames "mainlog", "paniclog", and "rejectlog". If you want to change | |
846 | # this, you can set LOG_FILE_PATH to a path name containing one occurrence of | |
847 | # %s. This will be replaced by one of the strings "main", "panic", or "reject" | |
848 | # to form the final file names. Some installations may want something like this: | |
849 | ||
850 | # LOG_FILE_PATH=/var/log/exim_%slog | |
851 | ||
852 | # which results in files with names /var/log/exim_mainlog, etc. The directory | |
853 | # in which the log files are placed must exist; Exim does not try to create | |
854 | # it for itself. It is also your responsibility to ensure that Exim is capable | |
855 | # of writing files using this path name. The Exim user (see EXIM_USER above) | |
856 | # must be able to create and update files in the directory you have specified. | |
857 | ||
858 | # You can also configure Exim to use syslog, instead of or as well as log | |
859 | # files, by settings such as these | |
860 | ||
861 | # LOG_FILE_PATH=syslog | |
862 | # LOG_FILE_PATH=syslog:/var/log/exim_%slog | |
863 | ||
864 | # The first of these uses only syslog; the second uses syslog and also writes | |
