Contoh File konfigurasi bisa di download pada link di bawah

INSTALL PHP5

$ sudo pkg_add http://openbsd.biz.net.id/4.1/packages/i386/php5-core-5.1.6p1.tgz

kalau PHP5 belum aktif aktifkan dengan perintah berikut:

$ sudo /usr/local/sbin/phpxs -s
[activating module `php5' in /var/www/conf/httpd.conf]
cp /usr/local/lib/php/libphp5.so /usr/lib/apache/modules/libphp5.so
 chmod 755 /usr/lib/apache/modules/libphp5.so
cp /var/www/conf/httpd.conf /var/www/conf/httpd.conf.bak
cp /var/www/conf/httpd.conf.new /var/www/conf/httpd.conf
rm /var/www/conf/httpd.conf.new

You should copy the sample configuration files from
/usr/local/share/examples/php5 to /var/www/conf/php.ini

copy php.ini dalam sample ke dalam /var/www/conf/
$ sudo cp /usr/local/share/examples/php5/php.ini-recommended /var/www/conf/php.ini

Untuk mengaktifkanmodul-modul dalam php misal :

$ sudo pkg_add -v http://openbsd.biz.net.id/4.1/packages/i386/php5-mysql-5.1.6p2.tgz
$ sudo /usr/local/sbin/phpxs -a mysql
Activating extension : mysql
$ sudo pkg_add http://openbsd.biz.net.id/4.1/packages/i386/php5-gd-5.1.6p2.tgz
$ sudo  /usr/local/sbin/phpxs -a gd
Activating extension : gd

Selanjutnya tinggal install modul-modul yang akan anda gunakan melalui packages installnya.
kenapa ? karana lebih mudah dan cepat heheheh :D

INSTALL MYSQL

$ sudo http://openbsd.biz.net.id/4.1/packages/i386/mysql-server-5.0.33.tgz
$ sudo  /usr/local/bin/mysqld_safe &
$ sudo /usr/local/bin/mysqladmin -u root password 'password_baru'

Masukan dalam /etc/rc.local startup script agar waktu di reboot mysql jalan kembali
$ sudo vi /etc/rc.local
masukan baris berikut :
====================

if [ X"${mysql}" == X"YES" -a -x /usr/local/bin/mysqld_safe ]; then
   echo -n " mysqld"; /usr/local/bin/mysqld_safe --user=_mysql --log --open-files-limit=256 &
   for i in 1 2 3 4 5 6; do
   if [ -S /var/run/mysql/mysql.sock ]; then
       break
       else
       sleep 1
       echo -n "."
   fi
 done
fi

===================
$ Vi /etc/rc.conf.local
tambahkan baris berikut :
================

mysql="YES"

===============

INSTALL POSTFIX

$ cd /usr/ports/mail/postfix

edit file Makefile.inc
$ sudo vi Makefile.inc

tambahkan mirror lokal indonesia pada MASTER_SITE_POSTFIX sehinga menjadi :
================

MASTER_SITE_POSTFIX=\
                ftp://mirror.cbn.net.id/pub/postfix-release/ \
                ftp://ftp.porcupine.org/mirrors/postfix-release/ \
                ftp://ftp.merit.edu/postfix/ \
                ftp://ftp.sunet.se/pub/unix/mail/postfix/ \
                ftp://ftp.tau.ac.il/pub/unix/mail/postfix/ \
                ftp://ftp.cs.uu.nl/mirror/postfix/postfix-release/

================

$ make show=FLAVORS
sasl2 ldap mysql pgsql db4
$ sudo env FLAVOR="sasl2 ldap mysql" make install 
--- postfix-2.3.7-sasl2-ldap-mysql -------------------
-> Creating /etc/mailer.conf.postfix
-> Creating Postfix spool directory and chroot area under /var/spool/postfix

    Warning: you still need to edit myorigin/mydestination/mynetworks
    parameter settings in /etc/postfix/main.cf.

    See also http://www.postfix.org/STANDARD_CONFIGURATION_README.html
    for information about dialup sites or about sites inside a
    firewalled network.

    BTW: Check your /etc/mail/aliases file and be sure to set up
    aliases that send mail for root and postmaster to a real person,
    then run /usr/local/sbin/newaliases.

+---------------
| Configuration files has been installed in /etc/postfix.
| Please update these files to meet your needs.
+---------------
+---------------
| Postfix can be set up to replace sendmail entirely. Please read the
| documentation at file:/usr/local/share/doc/postfix/html/index.html or
| http://www.postfix.org/ carefully before you decide to do this!

|
| To replace sendmail with postfix you have to install a new mailer.conf
| using the following command:
|
|     /usr/local/sbin/postfix-enable
|
| If you want to restore sendmail, this is done using the following command:
|
|     /usr/local/sbin/postfix-disable
+---------------

$ sudo  /usr/local/sbin/postfix-enable

old /etc/mailer.conf saved as /etc/mailer.conf.pre-postfix
postfix /etc/mailer.conf enabled

NOTE: do not forget to add sendmail_flags="-bd" to
      /etc/rc.conf.local to startup postfix correctly.

NOTE: do not forget to add "-a /var/spool/postfix/dev/log" to
      syslogd_flags in /etc/rc.conf.local and restart syslogd.

NOTE: do not forget to remove the "sendmail clientmqueue runner"
      from root's crontab.

$ sudo vi /etc/rc.conf.local
Ganti pada baris sendmail_flags= menjadi :
==========

sendmail_flags="-bd"

==========
kemudian pada baris syslogd_flags= menjadi
==========

syslogd_flags="-a /var/spool/postfix/dev/log"

==========
Kemudian tambahkan juga baris untuk menjalankan postfix agar setelah di restart kembali bekerja.
===========

postfix_flags="YES"

===========

Edit file /etc/rc.local kemudian tambahkan baris berikut :
==================================

# Postfix chroot Settings
if [ "X${postfix_flags}" != X"NO" ]; then
      mkdir -p /var/spool/postfix/var/run/mysql
      sleep 2
      ln -f /var/run/mysql/mysql.sock /var/spool/postfix/var/run/mysql/mysql.sock
fi

===================================

Konfigurasi Postfix:
Tentukan dimana akan diletakan file-file untuk email domain virual misal di sini kita letakan dalam /var/mail/virtual
$ sudo mkdir /var/mail/virtual
Ubah pemiliknya menjadi user: _postfix dan group : _postfix
$ sudo chown _postfix:_postfix /var/mail/virtual
Edit file konfigurasi postfix
$ sudo vi /etc/postfix/main.cf

Tambahkan Baris berikut:
=============

myhostname = isi_dengan nama server anda
mydomain = isi dengan nama domain server anda
myorigin = $mydomain
mydestination = $myhostname localhost.$mydomain $mydomain
alias_database = hash:/etc/mail/aliases
alias_maps = hash:/etc/mail/aliases
# postfixadmin stuff
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
virtual_gid_maps = static:507
virtual_mailbox_base = /var/mail/virtual
virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf
virtual_mailbox_limit = 51200000
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
virtual_minimum_uid = 507
virtual_transport = virtual
virtual_uid_maps = static:507
# Additional for quota support
virtual_create_maildirsize = yes
virtual_mailbox_extended = yes
virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql_virtual_mailbox_limit_maps.cf
virtual_mailbox_limit_override = yes
virtual_maildir_limit_message = Sorry, the user's maildir has overdrawn his diskspace quota, please try again later.
virtual_overquota_bounce = yes
# store backup mx domains in mysql
relay_domains = proxy:mysql:/etc/postfix/mysql_relay_domains_maps.cf
#sasl2 stuff
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions = 
      permit_mynetworks,
      permit_sasl_authenticated,
      reject_non_fqdn_hostname, 
      reject_non_fqdn_sender,
      reject_non_fqdn_recipient, 
      reject_unauth_destination,
      reject_unauth_pipelining, 
      reject_invalid_hostname,
      reject_rbl_client bl.spamcop.net

smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = $myhostname
smtpd_sasl_security_options = noanonymous

================

Selanjutnya buat file mysql map nya yang kita definisikan dalam main.cf
$ sudo vi /etc/postfix/mysql_virtual_alias_maps.cf
isi dengan baris berikut :
===========

user = postfix
password = p4ssw0rd
hosts = 127.0.0.1
dbname = postfix
query = SELECT goto FROM alias WHERE address='%s'
