[[Qmail + LDAP Configuration ]]

Qmail Downloads

Check for gcc

wget http://www.qmailrocks.org/downloads/qmailrocks.tar.gz

wget http://www.nrg4u.com/qmail/qmail-ldap-1.03-20060201.patch.gz

wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

rpm -Uhv rpmforge-release-0.3.6-1.el5.rf.i386.rpm

yum install openldap* yum install zlib* yum install glib yum install gcc-c++ yum install gdbm*

1. yum install openssl-devel

2.Qmail Downloads

First create a new directory where you will store your qmail package.

mkdir /downloads

cd /downloads

Download the qmail package (or tarball).

wget http://www.qmailrocks.org/downloads/qmailrocks.tar.gz

Download qmail-ldap patch.

wget http://www.nrg4u.com/qmail/qmail-ldap-1.03-20060201.patch.gz

Unpack the downloaded qmail package.

tar -zxvf qmailrocks.tar.gz

3.Creating initial qmail directories.

mkdir -p /var/qmail

mkdir /usr/src/qmail

4.Creating all needed users and groups:

groupadd nofiles

useradd -g nofiles -d /var/qmail/alias -s /sbin/nologin -p'*' alias

useradd -g nofiles -d /var/qmail -s /sbin/nologin -p'*' qmaild

useradd -g nofiles -d /var/qmail -s /sbin/nologin -p'*' qmaill

useradd -g nofiles -d /var/qmail -s /sbin/nologin -p'*' qmailp

groupadd qmail

useradd -g qmail -d /var/qmail -s /sbin/nologin -p'*' qmailq

useradd -g qmail -d /var/qmail -s /sbin/nologin -p'*' qmailr

useradd -g qmail -d /var/qmail -s /sbin/nologin -p'*' qmails

groupadd vmail

useradd -g vmail -s /bin/true vmail

5.Unpacking qmail, ucspi-tcp and daemontools

cd /usr/src/qmail

tar zxvf /downloads/qmailrocks/qmail-1.03.tar.gz

tar zxvf /downloads/qmailrocks/ucspi-tcp-0.88.tar.gz

mkdir -p /package

chmod 1755 /package

cd /package

tar zxvf /downloads/qmailrocks/daemontools-0.76.tar.gz

6.Creating & setting qmail logging directories.

mkdir /var/log/qmail

cd /var/log/qmail

mkdir qmail-send qmail-smtpd qmail-pop3d

chown -R qmaill:root /var/log/qmail

chmod -R 750 /var/log/qmail

7.Setting up the supervise script directories.

mkdir /var/qmail/supervise

cd /var/qmail/supervise

mkdir -p qmail-smtpd/log qmail-send/log qmail-pop3d/log

chmod +t qmail-smtpd qmail-send qmail-pop3d

8.Setting conf-split and conf-spawn.

echo 211 > /usr/src/qmail/qmail-1.03/conf-split

echo 255 > /usr/src/qmail/qmail-1.03/conf-spawn

9.Applying qmail-ldap patch.

cd /usr/src/qmail/qmail-1.03/

gzip -d qmail-ldap-1.03-20060201.patch.gz

patch -p1 < /downloads/qmail-ldap-1.03-20060201.patch

10.Make following changes to the Makefile and then save & close this file.

vi Makefile

---

LDAPFLAGS=-DQLDAP_CLUSTER -DEXTERNAL_TODO -DDASH_EXT -DSMTPEXECCHECK -DALTQUEUE

ZLIB=-lz

MDIRMAKE=-DAUTOMAILDIRMAKE

HDIRMAKE=-DAUTOHOMEDIRMAKE

SHADOWLIBS=-lcrypt

DEBUG=-DDEBUG

---

Save & Close this file.

11.Building qmail.

make setup check

Please enter the hostname in place of <hostname> like mailserver.krishnagroup.co.in ./config-fast <hostname>

12.Build ucspi-tcp:

cd /usr/src/qmail/ucspi-tcp-0.88/

patch < /downloads/qmailrocks/patches/ucspi-tcp-0.88.errno.patch

make && make setup check

13.Build daemontools:

cd /package/admin/daemontools-0.76/src

patch < /downloads/qmailrocks/patches/daemontools-0.76.errno.patch

cd ..

package/install

If you take a look at the running processes on your server at this point, you should see the daemon "svscanboot" running.

14.LDAP controls files.

#Sample access control policy:

#       Other DSEs:

# access to dn.base="cn=Subschema" by * read
# access to *
#       by self write
#       by users read
#       by anonymous auth
#
# if no access controls are present, the default policy
# allows anyone and everyone to read anything but restricts
