Was hoping for some ideas as to a service to which I can set up an inbound-only email system. In other words, I will have multiple users on the system, each can receive their own email... but at the moment... at this time, I am not focused on the ability to send or reply to messages, only receive them and send to the appropriate user. I looked into Postmark... They seem to have some great functionality.
CloudMailin Is another alternative. However there are effectively three options for setting up something like this.
I went through for of these for Rails a little while back here, but all the information is still relevant.
