I have an application that needs to send email for a couple of different @mydomain.com addresses. I'd also like to be able to read any replies sent to those addresses though a web client. I don't want to install and configure my own mail server, because I don't know anything about this, and don't think learning how to administer a mail server is a good use of my time, so instead I'd like to outsource it.
Google apps is pretty much exactly what I'm after, the cost is too high considering that the volume of email I'll be sending/receiving will be relatively low and I won't be using any of the other Google apps services.
Is there an alternative service to Google apps that my app could use to send email from my domain?
