################################################## # The Exim mail transport agent # ################################################## # This is the template for Exim's main build-time configuration file. It # contains settings that are independent of any operating system. It should # be edited and then saved to a file called Local/Makefile before first running # the make command. # Things that depend on the operating system have default settings in # OS/Makefile-Default, but these are overridden for some OS by files called # called OS/Makefile-. You can further override these by creating files # called Local/Makefile-, where "" stands for the name of your # operating system - look at the names in the OS directory to see which names # are recognized. # However, if you are building Exim for a single OS only, you can place all the # configuration settings in the one file called Local/Makefile; only if you are # building for several OS from the same source files do you need to worry # about splitting off the OS-dependent settings into separate files. # One OS-specific thing is the C compiler; the overall default is gcc, but # some OS Makefiles specify cc. You can override anything that is set by # putting CC=whatever in your Local/Makefile. # NOTE: You should never need to edit any of the distributed Makefiles; all # overriding can be done in your Local/Makefile(s). This will make it easier # for you when the next release comes along. # The location of the X11 libraries is something else that is quite variable # even between different versions of the same operation system (and indeed # there are different versions of X11 as well, of course). The four settings # concerned here are X11, XINCLUDE, XLFLAGS (linking flags) and X11_LD_LIB # (dynamic run-time library). # Another area of variability between systems is the type and location of the # dbm library package. Exim has support for ndbm, gdbm, and Berkeley db. By # default it assumes ndbm; this often works with gdbm or db, provided they # are correctly installed, via their compatibility interfaces. However, Exim # can also be configured to use the native calls for Berkeley db 1.85, and # this is defaulted for some operating systems. The defaults are set in # OS/Makefile-Default, and can be changed by putting things into an OS-specific # Makefile, or indeed into the main Local/Makefile if Exim is being compiled # for a single OS only. # See also the file doc/dbm.discuss.txt for discussion about different dbm # libraries. # In Local/Makefiles blank lines and lines starting with # are ignored. It is # also permitted to use the # character to add a comment to a setting, for # example # # EXIM_GID=42 # the "mail" group # # Consequently, it is not possible to have the # character present in any # setting, but I can't think of any cases where this would be wanted. ############################################################################### # /bin/sh is normally used as the shell in which to run commands that are # defined in the makefiles. This can be changed if necessary, but note that # a Bourne-compatible shell is expected. # MAKE_SHELL=/bin/sh # The following commands live in different places in some OS. The OS-specific # files should normally point to the right place, but they can be overridden # here if necessary. Perl is not necessary for running Exim unless you set # EXIM_PERL (see below) to get it embedded, but there are some Perl utilities # for processing log files. If you haven't got Perl, Exim will still build and # run; you just won't be able to run those utilities. # CHOWN_COMMAND=/usr/bin/chown # CHGRP_COMMAND=/usr/bin/chgrp # MV_COMMAND=/bin/mv # RM_COMMAND=/bin/rm # PERL_COMMAND=/usr/bin/perl # The following macro can be used to change the command for building a library # of functions. By default the "ar" command is used, with options "cq". # AR=ar cq # The binary directory: This variable defines where the exim binary will be # installed by "make install" or "exim_install". It is also used internally # by exim when it needs to re-invoke itself, either to send an error message, # or to recover root privilege. Exim's utility binaries and scripts are also # installed in this directory. There is no default for this variable built into # the source files; it must be set in one of the local configuration files. BIN_DIRECTORY=XX_PREFIX_XX/sbin # The default distribution of Exim contains only the plain text form of the # documentation. Other forms are available separately. If you want to install # the documentation in "info" format, first fetch the Texinfo documentation # sources from the ftp directory and unpack them, which should create files # with the extension "texinfo" in the doc directory. Then set INFO_DIRECTORY to # your info directory; "make install" will then build the info files and # install them there. INFO_DIRECTORY=XX_PREFIX_XX/info # The compress command is used by the exicyclog script to compress old log # files. Both the name of the command and the suffix that it adds to files # need to be defined here. See also the EXICYCLOG_MAX configuration. COMPRESS_COMMAND=/usr/bin/gzip COMPRESS_SUFFIX=gz # The runtime configuration file: This variable defines where Exim's runtime # configuration file is. There is no default built into the source files, so # there must be a setting in one of the local configuration files. The # location of all other runtime files and directories can be changed in the # runtime configuration file. CONFIGURE_FILE=XX_PREFIX_XX/etc/exim/configure # In some installations there may be multiple machines sharing file systems, # where a different configuration file is required for Exim on the different # machines. If CONFIGURE_FILE_USE_NODE is defined, then Exim will first look # for a configuration file whose name is that defined by CONFIGURE_FILE, # with the node name obtained by uname() tacked on the end, separated by a # period (for example, /usr/exim/configure.host.in.some.domain. If this file # does not exist, then the bare configuration file name is tried. # CONFIGURE_FILE_USE_NODE=yes # In some esoteric configurations two different versions of Exim are run, # with different setuid values, and different configuration files are required # to handle the different cases. If CONFIGURE_FILE_USE_EUID is defined, then # Exim will first look for a configuration file whose name is that defined # by CONFIGURE_FILE, with the effective uid tacked on the end, separated by # a period (for eximple, /usr/exim/configure.0). If this file does not exist, # then the bare configuration file name is tried. In the case when both # CONFIGURE_FILE_USE_EUID and CONFIGURE_FILE_USE_NODE are set, four files # are tried: .., ., ., and . # CONFIGURE_FILE_USE_EUID=yes # The size of the delivery buffer: This specifies the size of buffer which is # used when copying a message from the spool to a destination. The default # value built into the source is 8192. # DELIVER_BUFFER_SIZE=8192 # Included directors: These variables determine which individual director # drivers are included in the Exim binary. There are no defaults; those that # are wanted must be defined here by setting the appropriate variables to the # value "yes". The actions of each director are described in a separate chapter # in the manual. Including a director in the binary does not cause it to # be used automatically. It has also to be specified in the runtime # configuration file. DIRECTOR_ALIASFILE=yes DIRECTOR_FORWARDFILE=yes DIRECTOR_LOCALUSER=yes DIRECTOR_SMARTUSER=yes # The mode of the database directory: Exim creates a directory called "db" # in its spool directory, to hold its databases of hints. This variable # determines the mode of the created directory. The default value in the # source is 0750. # DB_DIRECTORY_MODE=0750 # Database file mode: The mode of files created in the "db" directory defaults # to 0640 in the source, and can be changed here. # DB_MODE=0640 # Database lock file mode: The mode of zero-length files created in the "db" # directory to use for locking purposes defaults to 0640 in the source, and # can be changed here. # DB_LOCKFILE_MODE=0640 # Cycling log files: this variable specifies the maximum number of old # log files that are kept by the exicyclog log-cycling script. EXICYCLOG_MAX=10 # Running Exim without it being root all the time: A uid and gid for Exim can # be specified here. These values are compiled into the binary. It is possible # to change them by settings in the runtime configuration file, but setting # them here is preferred. If EXIM_UID is not defined, the default in the code # is to run as root unless specified otherwise at run time. Specifying 0 at # run time has the effect of unsetting the values build into the binary. # The settings here must be numeric; the run time file allows names to # be used. When this uid and gid are set, the Exim binary still has to be # setuid root if local deliveries are to be performed or a listener on port # 25 is to be run, but it gives up its privilege when possible. There is a # trade-off between security and efficiency, controlled by the runtime # "security" setting, which controls how privilege is released (setuid vs # seteuid). # EXIM_UID= # EXIM_GID= # Compiling the Exim monitor: If you want to compile the Exim monitor, # a program that requires an X11 display, then EXIM_MONITOR should be # set to the value "eximon.bin". Comment out this setting to disable # compilation of the binary file that is run by the eximon script. The # locations of various X11 directories for libraries and include files # are defaulted in the OS/Makefile-Default file, and can be overridden # in local OS-specific make files. EXIM_MONITOR=eximon.bin # Compiling in support for embedded Perl: If you want to be able to # use Perl code in Exim's string manipulation language and you have Perl # (version 5.004 or later) installed, set EXIM_PERL to perl.o. EXIM_PERL=perl.o # There are also three options which are used when compiling the Perl interface # and when linking with Perl. The default values for these are placed # automatically at the head of the Makefile by the script which builds it. # However, if you want to override them, you can do so here. # PERL_CC= # PERL_CCOPTS= # PERL_LIBS= # This parameter sets the maximum length of the header portion of a message # that Exim is prepared to process. The default setting is one megabyte. There # is a limit in order to catch rogue mailers that might connect to your SMTP # port, start off a header line, and then just pump junk at it for ever. The # message_size_limit option would also catch this, but it may not be set. # HEADER_MAXSIZE=(1024*1024) # The mode of the input directory: The input directory is where messages are # kept while awaiting delivery. Exim creates it if necessary, using a mode # which can be defined here (default 0750). # INPUT_DIRECTORY_MODE=0750 # Exim log directory and files: Exim creates several log files inside a # single log directory. You can define the directory and the form of the # log file name here, by setting LOG_FILE_PATH to a path name containing one # occurrence of %s. This will be replaced by one of the strings "main", # "panic", "process" or "reject" to form the final file name. For example, # some installations may want something like this: LOG_FILE_PATH=/var/log/exim_%slog # which results in files with names /var/log/exim_mainlog, etc. The directory # in which the log files are placed must exist; Exim does not try to create # it for itself. It is also your responsibility to ensure that Exim is capable # of writing files using this path name. If you have defined EXIM_UID and # EXIM_GID above, then that uid and gid must be able to create files in the # directory you have specified. # You do not have to define the log file path here; an option in the runtime # configuration file can also set it, and that overrides any setting here. # However, it is recommended that you set it here if it is a fixed path, so # that it is available right from the start of Exim's execution. Otherwise, # errors detected early on, for example errors in the configuration file, # cannot be logged. # If you do not set LOG_FILE_PATH here or in the runtime configuration, Exim # creates a directory called "log" inside its spool directory (see # SPOOL_DIRECTORY below) and uses that with filenames "mainlog", "paniclog", # etc. Its mode defaults to 0750 but that can be changed here. # LOG_DIRECTORY_MODE=0750 # This value is used only when Exim creates the directory for itself. # The log files themselves are created as required, with a mode that defaults # to 0640, but which can be changed here. # LOG_MODE=0640 # Included file and database lookup methods. See the manual chapter entitled # "File and database lookups" for discussion. DBM and lsearch (linear search) # are included by default. LOOKUP_DNSDB does *not* refer to general mail # routing using the DNS. It is for the specialist case of using the DNS as # a general database facility (not common). For details of cdb files and the # tools to build them, see http://www.pobox.com/~djb/cdb.html. LOOKUP_DBM=yes LOOKUP_LSEARCH=yes # LOOKUP_CDB=yes # LOOKUP_DNSDB=yes # LOOKUP_LDAP=yes # LOOKUP_MYSQL=yes # LOOKUP_NIS=yes # LOOKUP_NISPLUS=yes # Additional libraries and include directories may be required for some # lookup styles, e.g. LDAP or MYSQL.

Unfortunately, though most of their functions are the # same, there is a difference in error handling. Currently Exim knows about # three LDAP libraries: the one from the University of Michigan, the Netscape # SDK library, and the library that comes with Solaris 7. Uncomment whichever # of these you are using. # LDAP_LIB_TYPE=UMICHIGAN # LDAP_LIB_TYPE=NETSCAPE # LDAP_LIB_TYPE=SOLARIS7 LDAP_LIB_TYPE=XX_LDAP_TYPE_XX # If you don't set any of these, Exim applies a heuristic to distinguish the # University of Michigan library, but it cannot distinguish between the other # two. # The TESTDB lookup is for performing tests on the handling of lookup # results, and is not useful for general running. It should be included # only when debugging the code of Exim. # LOOKUP_TESTDB=yes # Per-message logs: While a message is in the process of being delivered, # comments on its progress are written to a message log, for the benefit of # human administrators. These logs are held in a directory called "msglog" # in the spool directory. Its mode defaults to 0750, but can be changed here. # The message log directory is also used for storing files that are used by # transports for returning data to a message's sender (see the "return_output" # option for transports). # MSGLOG_DIRECTORY_MODE=0750 # Identifying the daemon: When an Exim daemon starts up, it writes its pid to # a file so that it can easily be identified. The path of the file can be # specified here. It must contain precisely one occurrence of "%s". When # a daemon is run on the default SMTP port, this is replaced with the null # string, but when it is run with some explicit port specified, "%s" is # replaced with the port number preceded by a dot. If a daemon is run with # only one of -bd and -q
