Creating Threads Based off of a Script from an RSS Feed

Hi, 

We also need something similar, but we do not have a RSS feed to base each automatic new thread. Instead, we were looking if there is a way to automatically create posts under a specific area, by following a simple action (eg: user sending an email to a board email address to automatically create a post under it) Any idea if there is a simpler way than writing a RESTcall?

Thanks, Zehra
