I'm building a web app that relies quite heavily on email notification/responses.
I obviously don't want to rebuild gmail from scratch(!) but I'm not sure how to integrate an existing webmail client into my site. I've looked at RoundCube, AtMail and Squirrel but still am not sure if they're what I need.
- For users of my app to use those applications would they be redirected away from my site, or can I use APIs to keep everything within my app?
Related to that, I only really need users to be able to read and respond to messages generated by my application. Although a full email client might be useful for some, it's not essential. I wonder whether a private message system (which could, if needed, send out emails to users registered address) might be more appropriate.
- Is this something I could relatively easily put together myself, or should I again be looking for an existing solution?
