it would involve the creation of primary module fused with XF core to be able to process incoming email message via server side script
I would like to start with server side script that parse text from incoming email message
based upon message text, module performs some function utilizing database.
on my server, I would setup email forwarder to pipe email to server side script anytime message is addressed to MyNewMedia@mydomain.com for example
script must already exist on the server
there must exist live process within xenForo to accept results from the script (basically the script is activating module functions)
so you get realtime performance from piping email to the script rather than resorting to a POP3 service which would require polling a mail queue on regular basis (CRON job?)
Everytime that you added a new video to your youtube channel, you could send email message (another automated task?) to your system addressed to MyNewMedia@mydomain.com where the message being piped to MyYoutubeChannel.php script would
alert the incomingmail module to handle including the video to your configured gallery configuration.
what tasks can you think of??
a customer support ticketing system also comes to mind
