How to get email reply on rails app from email server

Question

I need to implement messaging feature. When I send message to any user from my rails app then it also goes to users email. But what I need to implement if user who got the email make reply from gmail,yahoo..etc then the reply should also come into rails app. could anyone guide me some way.. so I can search it on google.

For Example:

If I send email to user from this email "[email protected]" and user replied on [email protected] which I set Reply-To in header. Then I need user's reply in my rails application so that I can add this user's reply into my messaging thread. By this feature which I want to implement User do not need to login in my application to do message, user can do message on current conversation via email reply also.

Since you tagged the question SendGrid, I'm assuming you're using it. You can use SendGrid's Inbound Parse Webhook to handle parsing incoming messages.

We also have a recent tutorial that goes through using the webhook in a rails app: http://sendgrid.com/blog/two-hacking-santas-present-rails-the-inbound-parse-webhook/
