GitHub action to setup an smtp server that saves emails to mongo, uses mailparser's ParsedMail as document schema. Intended only for development and test workflows.

Add the following to your workflow file to get smtp server running

steps:
- uses: debdutdeb/smtp-to-mongodb-action@main
  with:
    log-file: /tmp/smtp.log
    mongo-url: mongodb://localhost:27017

You can use supercharge/mongodb-github-action@1.10.0 with this action to get a mongo instance running.

Recommended structure is

steps:
- uses: supercharge/mongodb-github-action@1.10.0
  with:
    mongodb-version: "5.0"

- uses: debdutdeb/smtp-to-mongodb-action@main
  with:
    log-file: /tmp/smtp.log
    mongo-url: mongodb://localhost:27017

# after using the server

- run: |
    cat /tmp/smtp.log
  if: failure()

Once SMTP server is running you can use the server with smtp://localhost:2525, with no auth and tls.

By default emails are persisted on tests db, emails_received collection.

If using TypeScript/JavaScript, you can use this file to access the emails.

Document type for each email is ParsedMail.
