I'm in the process of deploying (on Ubuntu) an application that needs to send email. I was planning to install and configure Postfix, but having looked at the instructions, there seems to be a dizzying array of configuration options, most of which I don't understand.
So I'm now considering outsourcing the sending/receiving of email. All I really need is:
a very small number of accounts (5 or less) @mydomain.com
ability to send/receive email using these accounts
A web interface that you can use to send/receive email would be very useful, but not absolutely essential. I've looked at Google apps, but it's quite expensive if all you're using it for is email.
So I'm looking for either
a suggestion for who I should outsource the sending/receiving of email to
an idiot's guide to how to configure Postfix (or another server) to send/receive email
