You can build binary Courier RPMs directly from the tarball, using RPM version 4.0.2 or higher. For example:
rpmbuild -ta courier-version.tar.bz2
Because the RPMs can be built directly from the tarball, binary RPMs will not be distributed separately.
NOTE:
The first attempt to build binary RPMs will likely result in an error message requesting additional RPMs to be installed first, such as the LDAP server, MySQL and PostgreSQL databases, and various other development libraries.
Do not blow off these requirements, and attempt to hack your way around them. Install the required RPMs, and try again. These RPMs are required to build the full complement of Courier packages, and they may be removed after building Courier.
Parts of Courier that use these optional RPMs will be built into separate, optional subpackages, and will not be required to run Courier. The optional RPMs must be installed only for the duration of the build process.
Note that Courier does not allow itself to be built as root. A single mistake -- especially when trying to build a system-level utility -- can have serious consequences. Therefore the configuration script won't let you. There's an undocumented flag to disable the check, for folks who don't make mistakes :-) See the FAQ for instructions on how to configure RPM to build packages as non-root.
Building the RPM packages yourself will also result in the packages being customized for your system. This procedure builds the following packages:
courier.rpm
- the base mail server.courier-smtpauth.rpm
- install this package to
enable authenticated ESMTP, in the ESMTP server.courier-ldap.rpm
- module to authenticate
against an LDAP directory. Install this module if you would
like to use an LDAP directory to authenticate and manage mail
accounts. LDAP support requires the OpenLDAP library to be
installed. If OpenLDAP development libraries are not installed,
this package will be empty.courier-mysql.rpm
- module to authenticate
using a MySQL database. Install this module if you would like
to use a MySQL database to authenticate and manage mail
accounts. If MySQL development libraries are not installed,
this package will be empty.courier-pgsql.rpm
- module to authenticate
using a PostgreSQL database. Install this module if you would
like to use a PostgreSQL database to authenticate and manage
mail accounts. If PostgreSQL development libraries are not
installed, this package will be empty.courier-fax-version--1.%{_arch}.rpm
-
several supporting scripts for sending E-mails by fax.courier-pop3d.rpm
- the POP3 server.courier-imapd.rpm
- the IMAP server.courier-webmail.rpm
- the webmail server.courier-webadmin.rpm
- the web-based
administration tool (just the cgi-bin
wrapper,
actually, the remaining files are installed by other
packages).courier-maildrop.rpm
- maildrop mail
filter (required if you want to implement mail filtering).courier-mlm.rpm
- the couriermlm
mailing list manager.courier-sendmail-wrapper.rpm
- install this
package to create soft links from
/usr/bin/sendmail
, /usr/lib/sendmail
,
and several other popular places, to Courier's sendmail
wrapper. This package will not be created on Red Hat 7.3 and
later, which uses the Debian-derived alternatives mechanism.
The alternatives mechanism will be incorporated into the main
Courier package.courier-maildrop-wrapper.rpm
- install this
package to create soft links in the /usr/local/bin
subdirectory, for applications which expect to find
maildrop
in the /usr/local/bin
directory. maildrop
is also available as a
standalone package, which normally installs in the
/usr/local/bin
subdirectory. Courier includes an
integrated version of maildrop
, and you can
install this package to allow applications that are configured
for the standalone maildrop
version to use
Courier's integrated version instead.NOTE: these packages are built with certain
directories in a non-default location. Specifically, the
configuration files are installed in /etc/courier
,
the mail spool is installed in /var/spool/courier
,
and the manual pages are installed directly in
/usr/man
. Other configuration settings are left at
their defaults. If you need to change the defaults, you will have
to build your own packages.
NOTE: the first time the system boots after
installing the Courier RPM, the system may pause for several
minutes at the "Starting Courier" prompt. That's because the
startup script automatically creates test SSL certificates the
first time the script is executed (provided that SSL support is
available). This can take as much as 5-6 minutes on a slow
machine. Subsequent starts should take only a few seconds. Have
patience. Also note that the main Courier RPM has the ESMTP
server turned off. You must manually enable receiving mail via
ESMTP by editing the esmtpd
configuration file.
