PHP script to emulate POP3 login & retrieval of email from MS Exchange 2010

I'm not familar with either of these apps.  When requesting through the PHP class linked to above, the results come back as a plain text stdArray, so the question would be whether you can then rehash the content into the required form and push it back into these systems.  I would then run this on a cron job at whatever frequency is required.  I hope this helps.

Got a Neglected Question Alert on this one.  I'd like to suggest a slightly different approach.  I am not sure if this will meet your needs but I have used it in some applications with good results (It is a design pattern frequently found in help-ticket applications).  The thing is called an email pipe and it works like this.  An email address or perhaps several email addresses are set aside for automated processing.  Whenever a message arrives for one of the pipe addresses, instead of storing the email message in a mailbox file, the associated email pipe script is started and the entire message, including headers and body can be read from the standard input.  The pipe script can examine and parse the messages, update the data bases, re-send the messages to other email addresses, POST data to start asynchronous scripts, etc.

Since I have only implemented an email pipe on a Linux system I cannot give you the specifics for the Microsoft OS, but there may be a similar capability.  The code snippet contains an example of the PHP code used by a teaching example of an email pipe script.  

Best of luck with it, ~Ray

#!/usr/bin/php -q
<?php // /email_pipe/index.php


// THIS IS AN EMAIL PIPE SCRIPT.
// THIS SCRIPT IS STARTED AUTOMATICALLY FOR EACH MESSAGE.
// NOTE THAT THIS SCRIPT IS ABOVE THE /public_html/ DIRECTORY TO PREVENT ACCIDENTAL EXECUTION


// --> HOW DO WE KNOW WHICH EMAIL MESSAGES GET SENT HERE?
// THIS SCRIPT RECEIVES MESSAGES SENT TO email_pipe@your.org
// CREATE AN EMAIL MAILBOX EXCLUSIVELY FOR AUTOMATED PROCESSING.
// SET UP AN EMAIL FORWARD FOR THAT MAILBOX IN cPANEL->EMAIL LIKE THIS:
// 1...5...10...15...20...25...
// |/home/{account}/email_pipe/index.php


// --> WHEN YOU UPLOAD, THIS SCRIPT WILL BE MARKED RW-R-R BUT THAT IS WRONG
// THIS SCRIPT MUST BE MARKED EXECUTABLE x0755
// YOU CAN USE FTP SOFTWARE TO CHMOD TO RWX-RX-RX


// --> NOTE THE FIRST LINE OF THIS SCRIPT MUST SAY #!/usr/bin/php -q STARTING IN COLUMN ONE
// 1...5...10...15...20...25...
// #!/usr/bin/php -q
// <?php ... PROGRAM CODE FOLLOWS


error_reporting(E_ALL);

// USE THE OUTPUT BUFFER - THIS DOES NOT HAVE BROWSER OUTPUT
ob_start();

// COLLECT THE INFORMATION HERE
$raw_email = '';


// TRY TO READ THE EMAIL FROM STDIN
if (!$stdin = fopen("php://stdin", "R"))
{
    echo "ERROR: UNABLE TO OPEN php://stdin \n";
}

// ABLE TO READ THE MAIL
else
{
    while (!feof($stdin))
    {
        $raw_email .= fread($stdin, 4096);
    }
    fclose($stdin);
}


// REMOVE MULTIPLE BLANKS - AND OTHER PROCESSING AS MIGHT BE NEEDED
$raw_email = preg_replace('/ +/', ' ', $raw_email);

// SPEW WHAT WE GOT, IF ANYTHING, INTO THE OUTPUT BUFFER
var_dump($raw_email);

// CAPTURE THE OUTPUT BUFFER AND SEND IT TO SOMEONE ELSE VIA EMAIL
$buf = ob_get_contents();
mail ('you@your.org', 'EMAIL PIPE DATA', $buf);
ob_end_clean();

You don't run this script - it gets run for you by the email handler and it only runs when email arrives for the defined email address.  There is no cron involved.

I can only help with the part that I understand, and that is the interface with cPanel.  It's documented in the code comments.
