How to get a contact form working on OS X Server 10.8?

Question

Since PHP's mail() function does not seem to work on OS X Server (Mountain Lion), I was wondering what other ways there are to use a contact form for our website.
Anyone?

Answer 1

OK, tried and tested!
Here we go.
You are going to install PEARL wwithin php on the server and then download a package called PERL::Mail with all its dependencies:
Thanks to http://echodittolabs.org/blog/2011/09/os-x-107-lion-development-native-apache-ph p-homebrew-mysql-or-mariadb  for the step by step for PEAR.
Step 1
$ sudo /usr/bin/php /usr/lib/php/install-pear-nozlib.phar
Step 2
$ cat >> ~/.bashrc <<'EOF'
alias pear="php /usr/lib/php/pear/pearcmd.php"
alias pecl="php /usr/lib/php/pear/peclcmd.php"
EOF
Step 3.  (just in case)
$ sudo chmod o+x ./.bashrc
Step 4.
$ . ~/.bashrc
Step 5
$ sudo pear channel-update pear.php.net
Step 6.
$ sudo pecl channel-update pecl.php.net
Step 7. (may say nothing to update but thats cool)
$ sudo pear upgrade --force pear
Step 8.
$ sudo pear upgrade (ditto)
Step 9.
$ sudo pecl upgrade (ditto)
Step 10. (adds the include path to your php.ini)1
sudo sh -c "cat >> /etc/php.ini <<'EOF'
include_path = ".:/usr/lib/php:/usr/lib/php/pear"
EOF"
Step 11. (Installs the PEAR::Mail module - with all dependencies) 
$ sudo pear install --alldeps -f mail
Step 12. Test php script with Login SMTP Auth.
<?php
require_once "Mail.php";
$from = "mark <[email protected]>";
$to = "Fred <[email protected]>";
$subject = "Hi!";
$body = "Hi Mark23,\n\nHow are you?";
$host = "localhost"; // or address of smtp host if different
$username = "smtp username";
$password = "smtp password";
$headers = array ('From' => $from,
   'To' => $to,
   'Subject' => $subject);
$smtp = Mail::factory('smtp',
   array ('host' => $host,
     'auth' => true,
     'username' => $username,
     'password' => $password));
$mail = $smtp->send($to, $headers, $body);
if (PEAR::isError($mail)) {
   echo("<p>" . $mail->getMessage() . "</p>");
  } else {
   echo("<p>Message successfully sent!</p>");
?>
I was testing this on my local dev machine and not the server and kept getting a "need FQDN name for host" reject.  I added a  "localhost" variable to my dev machine FQDN and all was well.  I'm just telling you this if you test on a machine that IS NOT the  the smtp server host. 
Good luck! - Let me know how you go.
