Configuring Postfix and Dovecot

  • Turn off sendmail


service sendmail stop

chkconfig sendmail off

system-switch-mail

(select postfix)

  • Configure postfix and dovecot to allow the creation of mail subfolders


postconf -e 'home_mailbox = Maildir/'

  • Edit /etc/dovecot.conf and add the following to the end of the file:


mail_location = maildir:~/Maildir

namespace private {

separator = /

prefix = ""

inbox = yes

}

  • Add the following to /etc/dovecot.conf to enable the IMAP protocol:


protocols = imap

  • To configure the rest of postfix, take a look at this nice tutorial:
http://fedorasolved.org/server-solutions/postfix-mail-server

Start services:


service httpd start

chkconfig httpd on

service postfix start

chkconfig postfix on

service dovecot start

chkconfig dovecot on

service mysqld start

chkconfig mysqld on

  • Configure mysqld root password:


/usr/bin/mysqladmin -u root password 'new-password'

Add a "horde.conf" file to /etc/httpd/cond.d:


#

# Horde

#

<Directory /var/www/html/horde>

    # Comment out the following 3 lines to make Horde accessible from anywhere

    #Order Deny,Allow

    #Deny from all

    #Allow from 127.0.0.1

    Options +FollowSymLinks

    # horde.org's recommended PHP settings:

    php_admin_flag safe_mode off

    php_admin_flag magic_quotes_runtime off

    php_flag session.use_trans_sid off

    php_flag session.auto_start off

    php_admin_flag file_uploads on

    # Optional - required for weather block in Horde to function

    #php_admin_flag allow_url_fopen on

    # If horde dies while trying to handle large email file attachments,

    #  you are probably hitting PHP's memory limit.  Raise that limit here,

    #  but use caution

    # Set to your preference - memory_limit should be at least 32M

    #  and be greater than the value set for post_max_size

    #php_value memory_limit 32M

    #php_value post_max_size 20M

    #php_value upload_max_filesize 10M

    # /usr/share/pear is needed for PEAR. /var/www/html/horde is needed for Horde itself

    # TODO: Set an appropriate include_path, too. Might even increase speed a bit.

    php_admin_value open_basedir "/var/www/html/horde:/var/www/html/horde/config:/usr/share/pear:/tmp"

    php_admin_flag register_globals off

</Directory>

<Directory %{_sysconfdir}/%{name}>

    Order Deny,Allow

    Deny from all

</Directory>

# Deny access to files that are not served directly by the webserver

<DirectoryMatch "^/var/www/html/horde/(.*/)?(config|lib|locale|po|scripts|templates)/(.*)?">

    Order Deny,Allow

    Deny from all

</DirectoryMatch>

# Deny access to the test.php files except from localhost

<LocationMatch "^/horde/(.*/)?test.php">

    Order Deny,Allow

    Deny from all

    Allow from 127.0.0.1

</LocationMatch>
