    S3 Email

    S3 Email

    A serverless email server on AWS using S3 and SES

    This solution is free for anyone to use and learn from. If you’d like to see more projects like this one, consider using some of our products from the AWS Marketplace or share them with someone you might think would be interested in using them. This stack was created out of frustration due to the fact that to this day there's no easy way to have a full email server without the overhead of installing and configuring all servers needed to handle incoming and outgoing messages. 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.
