This is the GNU Mailutils package
=================================
* Introduction
==============
GNU Mailutils is a rich and powerful protocol-independent mail
framework. It contains a series of useful mail libraries, clients,
and servers. These are the primary mail utilities for the GNU system.
The central library is capable of handling electronic mail in various
mailbox formats and protocols, both local and remote. Specifically,
this project contains a POP3 server, an IMAP4 server, and a Sieve mail
filter. It also provides a POSIX `mailx' client, and a collection of
other handy tools.
The GNU Mailutils libraries supply an ample set of primitives for
handling electronic mail in programs written in C, C++, Python or
Scheme.
At the core of Mailutils is libmailutils, a library which provides
universal access to various mailboxes and protocols: UNIX mailbox,
Maildir, MH, POP3, IMAP4, Sendmail, SMTP. Mailutils offers functions
for almost any mail-related task, such as parsing of messages, email
addresses and URLs, handling MIME messages, listing mail folders,
mailcap facilities, extensible Sieve filtering, access control lists.
It supports various modern data security and authentication
techniques: TLS encryption, SASL and GSSAPI, to name a few.
The framework is able to work with a wide variety of authorization
databases, ranging from traditional system password database up to
RADIUS, SQL and LDAP.
The utilities provided by Mailutils include imap4d and pop3d mail
servers, mail reporting utility comsatd, general-purpose mail delivery
agent maidag, mail filtering program sieve, and an implementation of
MH message handling system.
All utilities share the same subset of command line options and use
a unified configuration mechanism, which allows to easily configure
the package as a whole.

* Why use this package?
=======================
This package started off to try and handle large mailbox files more
gracefully then current POP3 servers did. While it handles this task,
it also allows you to support a variety of different mailbox formats
without any real effort on your part. Also, if a new format is added
at a later date, your program will support that new format
automatically as soon as it is compiled against the new library.
This package is also released as part of Debian, so you should expect
it to compile cleanly on all the platforms supported there.
* How to install
================
Please see the INSTALL file in this directory for the generic instructions
on how to use configure. The following short summary describes the
mailutils-specific configuration options:
--enable-debug
Compile Mailutils with debugging support. This disables
compiler optimizations and adds debugging information to the
binaries.
--disable-pam
Do not build PAM support. By default configure will build PAM
support if the host system supports it. Use this option to
suppress this behaviour.
--disable-pthread
Do not build thread-safe libraries.
--without-fribidi
Do not include fribidi support, even if libfribidi is present.
--with-sql=MODLIST
Enable support for authentication using given SQL modules.
MODLIST is a colon-separated list of SQL modules to use.
Available modules are 'mysql', 'postgres' and 'odbc'. E.g.,
to enable all modules:
--with-sql=mysql:postgres:odbc
Note that depending on how your SQL systems are installed,
this may require adding appropriate directories to the library
and include paths, e.g.
./configure LDFLAGS='-L/usr/local/mysql/lib -L/usr/local/pgsql/lib' \
CPPFLAGS='-I/usr/local/mysql/include \
-I/usr/local/pgsql/include'
--with-sql=mysql:postgres
--with-mysql
Equivalent to --with-sql=mysql
Note that depending on how your MySQL system is installed, this
may require adding appropriate directories to the library and
include paths, e.g.:
./configure LDFLAGS='-L/usr/local/mysql/lib' \
CPPFLAGS='-I/usr/local/mysql/include' --with-mysql
--with-postgres
Equivalent to --with-sql=postgres
You may have to explicitly specify LIBS and CPPFLAGS (see
above).
--with-odbc[={odbc|iodbc}]
Without arguments or with 'odbc' as its argument it is
equivalent to --with-sql=odbc.
--with-odbc=iodbc enables ODBC support via libiodbc.
You may have to explicitly specify LIBS and CPPFLAGS (see
above).
--with-mh-bindir=DIR
By default the MH binaries are installed in
${exec_prefix}/bin/mu-mh. To change this, use --with-mh-bindir
option. If DIR starts with '/' it is taken as an absolute
path specification, otherwise ${prefix} is prepended to it.
--with-virtual-pwddir=DIR
Use DIR instead of $sysconfdir/domain as the location of
virtual mail domain database. This option is ignored if
--disable-virtual-domains is specified.
--without-readline
Build 'mail' without readline support.
--without-gnutls
Disable the TLS/SSL encryption via GnuTLS (a Transport Layer
Security Library) in IMAP4/POP3 daemons and utilities.
--without-gsasl
Disable GNU SASL support.
GSASL is used by several Mailutils components (notably pop3d
and imap4d as well as their client counterparts) for
authentification. It is enabled by default if configure
detects the presense of GNU SASL version 0.2.3 or later.
--with-gssapi
Enable GSSAPI authentication. For this to work, you will have
to have Kerberos V installed on your system.
--without-python
Do not build Python interface library.
--without-guile
Do not build Guile interface library.
--with-guiledir[=DIR]
Specify the directory to install guile modules to. By default
they are installed in
$(prefix)/share/mailutils/$(VERSION)/guile.
The option --with-guiledir used without argument instructs
configure script to install modules to the site-wide Guile
directory, where it is easier to find them. This directory is
defined as $(guile_pkgdatadir)/site where guile_pkgdatadir is
the Guile package data directory as returned by `guile-config
info pkgdatadir'.
Otherwise, if an argument to the option is given, it specifies
the absolute file name of the installation directory for Guile
modules.
--with-mail-rc=FILE
Set the location of the system-wide configuration file for mail
utility. FILE must be an absolute filename specification.
Default is $sysconfdir/mail.rc
--with-mail-spool=PATH
Override the location of the mailspool. The default value
depends on the system. Usually it is either /var/spool/mail
or /var/mail. PATH is either an absolute directory name, or a
valid `mbox' URL in the form:
mbox:path;type=TYPE;param=N;user=
This method allows you to use indexed mailspools. For servers
with a really big number of users this may provide a
significant speedup in opening the mailbox.
TYPE is one of:
hash -- The user's mailbox is kept in a subdirectory
whose name is determined by hashing first
N characters of the user name. There are
256 subdirectories named from 00 through FF.
index -- The user's mailbox is located PARAM directories
down the `path'. The directories are named
after the first N letters of a login name.
For example, when N=2 the mailbox for
user `smith' is `/var/spool/mail/s/m/smith'.
rev-index -- Same as above, except that the last letters
are used, thus the mailbox for `smith' will
be /var/spool/mail/h/t/smith. This may provide
a better average distribution than the `index'
method.
--with-log-facility=facility
Enable logging to the given syslog facility. Default is `mail'.
--without-included-regex
Don't compile regex; this is the default on systems with version
2 of the GNU C library (use with caution on other systems)
--disable-nls
Do not use Native Language Support
--with-included-gettext
Use the GNU gettext library included in the Mailutils distribution.
--with-included-argp
Use the argp library supplied with the package, instead of the
one from your libc. You will need this option if the libc library
on your system was compiled without NLS support.
The following options enable DBM support in Mailutils. DBM support is
necessary if you wish to use APOP authentication in POP3 daemon or to
use DBM-based mail box quotas with maildag.
--with-gdbm
Use GNU DBM
--with-berkeley-db[=ARG]
Use Berkeley DB. If ARG is not specified, configure will
attempt to autodetect the database version to use. Unless ARG
begins with a digit, it is taken as a library name, without
the `lib' prefix and library type suffix, so that specifying
--with-berkeley-db=db-3.1
instructs configure to use library libdb-3.1.so (or
libdb-3.1.a).
Otherwise, if ARG begins with a digit, it is understood as a
library version number to link to. In this case configure
assumes a Slackware-like installation layout. Thus, using
--with-berkeley-db=3.1
tells configure to use library libdb-3.1.so (or libdb-3.1.a)
and header file /usr/include/db31/db.h
--with-ndbm
Use NDBM
--with-tokyocabinet
Use Tokyo Cabinet DBM
--with-kyotocabinet
Use Kyoto Cabinet DBM
Use following options to disable support for particular protocols or
features:
--disable-imap Disables IMAP protocol support.
--disable-pop Disables POP protocol support.
--disable-smtp Disables support for SMTP mailer.
--disable-sendmail Disables support for `Sendmail' mailer.
--disable-mh Disables support for MH mailbox format.
--disable-virtual-domains
Disables support for authentication using
virtual mail domains.
Mailutils is shipped with a set of various utilities, which are built
by default. These utilities fall into two groups:
a) Server utilities: pop3d, imap4d and comsat.
b) Client utilities: frm, maidag, mail, sieve, messages, readmsg,
dotlock, movemail mimeview, and MH utilities.
The following options disable each group:
--disable-build-servers do not build server utilities
--disable-build-clients do not build client utilities
Each particular program can be disabled using its individual
`--disable-build' option:
--disable-build-frm do not build frm
--disable-build-pop3d do not build pop3d
--disable-build-imap4d do not build imap4d
--disable-build-comsat do not build comsat
--disable-build-maidag do not build maidag
--disable-build-mail do not build mail
--disable-build-sieve do not build sieve
--disable-build-guimb do not build guimb
--disable-build-messages do not build messages
--disable-build-readmsg do not build readmsg
--disable-build-dotlock do not build dotlock
--disable-build-movemail do not build movemail
--disable-build-mimeview do not build mimeview
--disable-build-mh do not build MH utilities
Several environment variables affect the configuration. Currently,
the only mailutils-specific variable is DEFAULT_CUPS_CONFDIR. It
sets the location of CUPS (Common UNIX Printing System) configuration
directory, which is needed for `mimeview' utility. By default, this
location is $sysconfdir/cups. On most sites, however, it may be
reasonable to set it to /etc/cups, e.g.:
./configure DEFAULT_CUPS_CONFDIR=/etc/cups ...
