hMailServer For Windows Installation Guide

hMailServer is a free e-mail server for Microsoft Windows. It supports all the common e-mail protocols such as, SMTP, POP3 and IMAP.

If you are on a tight budget to purchase a commercial mail server, this is a good choice of having a reliable mail server that cost virtually nothing, except your effort you put to configure it.

I wrote this installation guide based on my experience in setting up a workable system.

Prerequisites

These prerequisites are necessary to have if you want a web mail that works with hMailServer.

1. Apache
2. PHP
3. MySQL
4. Perl

hMailServer Installation

Stop the SMTP Service in IIS (Internet Information Services). It will clash with hMailServer because both are using the same port 25.

Download the latest hMailServer from http://www.hmailserver.com

Launch the installer and follow the installation instruction.

Enter a password for hMailServer Administrator.

Launch the hMailServer Administrator.

Click Settings > Protocols > SMTP, and select the “Delivery of email” tab.

Enter the Host name and click Save.

Right-click Domains menu, then click Add.

Enter a new Domain name. Eg. mydomain.com

Enter a catch-all address. Eg. catch-all@mydomain.com

Click Save.

Expand the newly created Domain and click “Add account”.

Enter an Account Address and Password.

Click Save.

Repeat the steps to create additional accounts.

Apache Installation

Download the latest Apache 1.3.x from http://httpd.apache.org/

Launch the installer and follow the installation instruction.

Edit httpd.conf

Enter an e-mail address in ServerAdmin.

Enter a ServerName.

Modify DocumentRoot if necessary to point to the root directory. Eg. D:/www
Note the forward slash “/”.

The default root directory is at C:/Program Files/Apache Group/Apache/htdocs, or in a different folder location where the Apache program is installed.

Add: index.php to DirectoryIndex. Place it before index.html.

Add: LoadModule php5_module “C:/php/php5apache.dll”

Uncomment: LoadModule vhost_alias_module modules/mod_vhost_alias.so

Uncomment: LoadModule rewrite_module modules/mod_rewrite.so

Add: AddModule mod_php5.c

Uncomment: AddModule mod_vhost_alias.c

Uncomment: AddModule mod_rewrite.c

Save the changes.

Start Apache Service and verify there is no error.

PHP + PEAR Installation

Download the latest PHP 5.2.x Zip Package (not installer package) from http://www.php.net/

Unzip it to C:\PHP folder.

Rename php.ini-recommended to php.ini and copy it to C:\Windows folder.

short_open_tag = On
max_execution_time = 60
post_max_size = 20M
upload_max_filesize = 20M
include_path=”.;C:\PHP\PEAR;C:\PHP”
extension_dir = “C:\PHP\ext”

Uncomment:

extension=php_curl.dll
extension=php_gd2.dll
extension=php_gettext.dll
extension=php_ldap.dll
extension=php_mbstring.dll
extension=php_mcrypt.dll
extension=php_mhash.dll

Download the PEAR DB package from http://pear.php.net/package/DB/

Unzip it into C:\PHP\PEAR folder. Make sure the DB.php is in that folder.

Restart Apache and verify there is no error.

Create a phpinfo.php with the following code and place it in the root directory.

<?php
echo phpinfo();
?>

Browse the phpinfo.php in web browser. PHP installation is successful if information is displayed.
