S3 Email
A serverless email server on AWS using S3 and SES
...We wanted something simple, with no interface and no server management, so we came up with S3-Email. This included AWS SES as our email server (receive and send) and S3 as our database and interface. Then we tied everything together with a bit of code via AWS Lambda. The result is an unmanaged email server with unlimited email addresses that also offers the benefit of easily organizing messages by adding the + character to the email names. The + is converted to a /, which correlates to an object path in S3.
