A Node.js Lambda function that utilizes Amazon SES to forward incoming emails to an email address inbox. Setup Amazon SES to receive emails and deliver to a S3 bucket, then invoke lambda to forward the email to your email of choice.

Diagram

• Serverless... no servers required because of Lambda.
• Cheap... can cost as low as a few cents.
• Parse email attachments. Saves attachments to S3 and insert download links into email. Avoid SES email size limitations.
  • Receiving email: 30 MB
  • Sending email: 10 MB

1. Domain name
2. AWS account
3. Unsanboxed Amazon SES account
4. Verify your domain

npm install

Create the following file inside the config folder.

exports.config = {
 attachmentPrefix: 'attachments/', // Attachment folder
 bucket: '', // S3 bucket
 cloudFront: '', // CloudFront distribtion domain name for S3 bucket (optional and you must setup this yourself first)
 forwardTo: [], // Email address destination
 from: '', // The email address that is sending the email.
 keyPrefix: 'email/', // Key prefix for S3 bucket
 region: '', // The region to send service requests to (not required if using CloudFront)
 sendingRate: 1, // How many messages per second is allowed to be delivered to SES
};

serverless package

serverless deploy --package .serverless

Create a receipt rule set

1. Create recipients
2. Create 2 actions in this exact order. S3 first, then Lambda.
   1. S3 action
      • S3 bucket - The name of the Amazon S3 bucket to which to save received emails.
      • Object key prefix - A key name prefix to use within the Amazon S3 bucket. (for example, email/)
      • Uncheck encrypt message (NOT RECOMMENDED because S3 client-side encryption is currently not supported for JavaScript. See documentation)
      • SNS Topic - Choose "None"
   2. Lambda action
      • Lambda function: Choose the function that you created during deployment.
      • Invocation type: Choose "Event"
      • SNS Topic - Choose "None"
