I don't agree with this. Having worked on the product side of several larger scale email infrastructures, it's impossible to scale this correctly. Yes, we all want to talk less with robots and appreciate getting a reply from a human, but if you're a web company looking to grow your product to be used by millions, you can't get this to work while keeping your co-workers happy (when I discussed something similar with our community support team they looked at me like they wanted to kill me).

There might be a way to scale it by filtering messages and sending certain replies on certain topics, but then again, your support team will ask you where the reply address will redirect to. Who will manage that inbox? Who needs to reply those emails? Do you want to increase the load on your support guys even more?
