Try this one.

<?php 
# Global variables 
$from = escapeshellcmd($_POST["from"]); 
$subject = escapeshellcmd($_POST["subject"]); 
$message = escapeshellcmd($_POST["message"]); 

# Function to check if email address is valid 
function valid_email($from) { 
 if (ereg("^[a-zA-Z0-9_]+@[a-zA-Z0-9\-]+\.[a-zA-Z0-9\-\.]+$", $from)) 
 return true; 
 else 
 return false; 
} 

# Function to check if $subject input is valid 
function valid_input($subject) { 
 if (preg_match('/^[\w\s\.]+$/', $subject)) 
 return true; 
 else 
 return false; 
} 

# Prints out the email form 
if(!$_POST) { 
 echo "<form method='post' action='$_SERVER[PHP_SELF]'>"; 
 echo "Your emailaddress<br><input type='text' name='from' size=60><br>"; 
 echo "Subject<br><input type='text' name='subject' size=60><br>"; 
 echo "Message<br><textarea name='message' cols=52 rows=11></textarea><br>"; 
 echo "<input type='submit' value='SendMail'>"; 
 echo "</form>"; 
} 

# Checks if from, subject and message is filled out 
elseif(!($from and $subject and $message)) { 
 echo "All fields are required to send an email!<br>"; 
 echo "<a href='$_SERVER[PHP_SELF]'>Try again</a>"; 
} 

# Checks if the email address is valid 
elseif(!valid_email($_POST['from'])) { 
 echo "Invalid email address. A valid mail address is e.g : [e-mail]<br>"; 
 echo "<a href='$_SERVER[PHP_SELF]'>Try again</a>"; 
} 

# Checks if the input is valid (excluding special characters) 
elseif (!valid_input($_POST['subject']) or !valid_input($_POST['message'])) { 
 echo "Invalid input. Tip : avoid using special characters. Only letters, numbers and dots are allowed<br>"; 
 echo "<a href='$_SERVER[PHP_SELF]'>Try again</a>"; 
} 

else { 
 # Sends the mail. (Change address below to your address) 
 mail("[e-mail]", $subject, $message, "From: $from"); 
 echo "Your mail is sent!</p>"; 
 echo "<a href='$_SERVER[PHP_SELF]'>Try again</a>"; 
} 
?>

Hi Chris
Thanks for the code but unfortunately I have a few problems, I get this errors:

All fields are required to send an email!
Invalid email address. A valid mail address is e.g : [e-mail]
Invalid input. Tip : avoid using special characters. Only letters, numbers and dots are allowed
Try again

Do you know by any change what could be wrong? I would really appreciate all your help, thanks

Those are not errors. They are codes Iv written to check if mailaddress is valid, that all
fields are filled out, etc. But If you dont want them iv removed them in the script below. :

<?php 
# Global variables 
$from = escapeshellcmd($_POST["from"]); 
$subject = escapeshellcmd($_POST["subject"]); 
$message = escapeshellcmd($_POST["message"]); 

# Prints out the email form 
if(!$_POST) { 
echo "<form method='post' action='$_SERVER[PHP_SELF]'>"; 
echo "Your emailaddress<br><input type='text' name='from' size=60><br>"; 
echo "Subject<br><input type='text' name='subject' size=60><br>"; 
echo "Message<br><textarea name='message' cols=52 rows=11></textarea><br>"; 
echo "<input type='submit' value='SendMail'>"; 
echo "</form>"; 
} 

else { 
# Sends the mail. (Change address below to your address) 
mail("[e-mail]", $subject, $message, "From: $from"); 
echo "Your mail is sent!</p>"; 
echo "<a href='$_SERVER[PHP_SELF]'>Try again</a>"; 
} 
?>
