A server that supports PHP. A server that supports http://php.net/mail function.
Some basic understanding of PHP includes.

================================================================================
Installation
================================================================================
You should have some basic knowledge about form in html. Open test.html, you 
will see a very basic sample form code.
hidden fields are:
  <input type="hidden" name="required_fields" 
value="subject,after_url,name,email,message" />
	-- put all the names of the required fields in here

  <input type="hidden" name="your_email_address" value="you@yourdomain.com" />
	-- put your real email address here or to do it a more secure way, check 
out "Customize your email address" section

  <input type="hidden" name="check_email_address" value="yes" />
	-- put "no" if you do not want the script to check the sender's email 
address for validity.

  <input type="hidden" name="subject" value="DodosMail" />
	-- you can have this field either as text or hidden. if it's text, then 
sender may change the subject of the email freely, otherwise it'll be 
the same subject regardless who sends it.




================================================================================
How to use captcha (take a look at captchaTest.php)
================================================================================
You must have PHP & GD library installed on your server for this to work. 

First you must indicate in your form that you plan to use this feature by 
putting the code below in your form:
	<!-- indicate below that you will use captcha -->
	<input type="hidden" name="use_dodos_captcha" value="yes" />

Then you must include a field that allows the user to input the text and link 
the captcha image by doing something like:
	Spam protection (enter the text <img 
src="dodoscaptcha.php?captchabgcolor=EEEEEE&amp;captchatextcolor=900000" 
style="vertical-align: middle" /> below):
	<br />
	<input type="text" name="use_dodos_captcha_typed" size="6" /> 

Notice you may change the background and text color by passing the hexcode for 
the two colors. If you do not pass in any colors, you will have black text on 
white background.

If the image does not show up on your page after you have included the file, 
it's most likely GD library is not appropriately installed. Please contact your 
host for more information.

----------------REMEMBER----------------
The two variable names:
use_dodos_captcha
use_dodos_captcha_typed
They may only be used for captcha purpose.




----------------------------------------------------------------------------

  <input type="hidden" name="use_dodos_captcha" value="yes" />
Spam protection (enter the text <img 
src="dodoscaptcha.php?captchabgcolor=EEEEEE&amp;captchatextcolor=900000" 
style="vertical-align: middle" /> below):
	<br />
	<input type="text" name="use_dodos_captcha_typed" size="6" />

	-- put "no" in the value if you do not wish the sender to get an auto 
response mail from you.
	
  <input type="hidden" name="owner_name" value="me" />
	-- replace "me" with YOUR NAME (the owner of the mail form)

  <input type="hidden" name="response_subject" value="Thank you for your mail!"

form. Thanks!" />

  <input type="hidden" name="after_url" value="thankyou.html" />
	-- this is the url where you want the mail form to redirect to after it 
has successfully sent the mail. if want the dodosmail to print an output 
instead of redirect. just get rid of this line. if you got rid of it, 
dodosmail will print something like:

	The following has been sent successfully!
		name: test
		email: test@regretless.com
		message: just a test
		money: no money
		food: need food

	with your css file definition




================================================================================
IMPORTANT NOTE!
================================================================================
Please do not use the following variable names other than for layout purpose. 
They are all reserved variable names.

"css_file", "background_color", "background_image", "text_color", "link_color", 
"visited_link_color", "active_link_color", "font_name", "font_size", 
"highlight_color", "required_fields", "after_url", "check_email_address", 
"subject", "your_email_address", "env_report", "owner_name", "autoresponse", 
"response_subject", "response_mail", "dodosmail_header_file", 
"dodosmail_footer_file"

If you wish to use checkbox in your form, the name of your check box must end 
with []. For example:
<input type="checkbox" name="checkboxtest[]" value="1">1 
<input type="checkbox" name="checkboxtest[]" value="2">2 
<input type="checkbox" name="checkboxtest[]" value="3">3 
<input type="checkbox" name="checkboxtest[]" value="4">4




================================================================================
Modify Header and Footer
================================================================================
The values for your header and footer files can be modified at two locations. 
	put in the correct file names for:
	<input type="hidden" name="dodosmail_header_file" value="header.php" />
	<input type="hidden" name="dodosmail_footer_file" value="dodofooter.php" 
/>
	in the form code




================================================================================
Add more fields
================================================================================
You can add as many new fields as you want. Please keep in mind name the fields 
using smart naming techniques. NO SPACES!! ALWAYS USE UNDERSCORE!!! or your mail 
script wont work!

for exmaple:
	Who's your favorite singer?
	<input type="text" name="favorite_singer" />




================================================================================
Customize your email address
================================================================================
There are two ways to put your email address in this script. You can either put 
it in the form as an hidden field or you can hide your email address from the 
public and put it in the dodosmail.php

WAY ONE:
	put in your correct address for:
	<input type="hidden" name="your_email_address" 
value="you@yourdomain.com" />
	in the form code

	**********
	advantage:
	**********
	without modifying dodosmail.php, you can call this script from anywhere 
and as many times as you want.
	*************
	disadvantage:
	*************
	your email address is not really hidden, people can still find it out by 
view source

WAY TWO:
	open dodosmail.php
	get rid of the "##" in front of 
$your_email_address="you@yourdomain.com";
	and replace you@yourdomain.com with your real email address
	delete
	<input type="hidden" name="your_email_address" 
value="you@yourdomain.com" />
	in the form code

	**********
	advantage:
	**********
	your email address is now truly hidden from public. no one can view it 
from the server.
	*************
	disadvantage:
	*************
	if you wish to set up another mail form to ANOTHER email address, you 
must use a second copy of dodosmail.php
