How do I parse emails in realtime as they are recieved

I need to build an email parsing script which would parse emails that would come into an inbox and dump the contents into a database, while at the same time make a curl request with details parsed from the email.

At this moment I’m quite stuck on implementing the part on how to parse emails in realtime as they are recieved in the inbox. Is there a way to set triggers to do something like this? I’ve extensive experience with working with php based webmail clients but this seems different though.

How can this be accomplished – I am assuming a cron job but if theres another way to do so I’m all ears.

Answer

Yes, there is. You can pipe emails to your scripts.

Assuming you are using cPanel, follow this steps:

• Log in to your cPanel.
• Click on the Forwarders icon, under the Mail tab.
• Click on the Add Forwarder button.
• Fill in Address to Forward and put the mail address you would like to pipe the messages from.
• Select Pipe to a Program and fill in the full path to the script which will handle the messages.

And here is a mail catcher example that sends received email to your other mail (just for demonstration):

#!/usr/bin/php -q
<?php
 
// read from stdin
$fd = fopen("php://stdin", "r");
$email = "";
while (!feof($fd))
{
    $email .= fread($fd, 1024);
}
fclose($fd);
 
 
mail('[e-mail]','From my email pipe!','"' . $email . '"');
 
?>
