This is neat, but it's not too difficult to handle incoming mail yourself with postfix and a simple ruby/python script to process it. The learning curve is slightly steep due to postfix and some really bad suggestions, but the actual work is straight forward.
I setup a simple ruby program to pipe the postfix email into a resque queue (redis backed ruby jobs system) to be handled by my work pool...a couple easy regexes determine what the email is: bounces get auto-delisted after 2x, unsubscribes delist immediately, replies get shoved into the correct in-site comment thread or conversation, etc. This is a day of work....
You are correct, of course. Nothing stops you from doing this yourself. The basic functionality in SaaS is always easy to accomplish (hosting, email sending, dropbox, etc). Its the little things that get you and eventually drive you to the bottle.
