I am developing a webapp that lets you update your account by sending a simple text email, then it sends a simple email back confirming it. This was working fine at my previous host, who had cPanel with email piping.
Since then, I’ve moved to dreamhost, particularly because lifehacker rated it #1 and gave an incredible discount. I’ve found them great so far. But then when I tried to transfer over the email piping feature they told me they do not support email piping. The only thing they support is Forwarding mail to a shell account which requires you to upgrade to a VPS anyway.
So what alternatives do I have? The only thing I can think of is having a cronjob executed every 5 seconds that checks an email account via POP/IMAP, but (1) that sounds quite intensive on the server to have that running every 5 seconds, and (2) from the sounds of that wiki article and what support has told me, I think that is what requires a VPS account anyway…
Help!
Here’s another option, a service that consumes email and posts to a form of your choosing:
