mailing caught error Error: getaddrinfo ENOTFOUND smtp.example.com

Describe the bug Not able to get the test server to force send with the correct config settings, maybe im missing something. I tried changing /emails/index.ts transport, but still getting the following error.

mailing caught error Error: getaddrinfo ENOTFOUND smtp.example.com

even with /emails/index.ts config

const transport = nodemailer.createTransport({
  host: 'smtp.mailtrap.io',
  port: 2525,
  auth: {
    user: 'username',
    pass: 'password'
  }
});

To Reproduce Steps to reproduce the behavior:

I must be missing a config step, but i updated the transport config in the /emails/index.ts, and when I run npx mailing, then send

1. run npx mailing to init project inside nextjs app
2. change the config in emails/index.ts in transport ensuring host is different
3. restart mailing server
4. trigger send email within main nextjs app so it gets intercepted by mailing server
5. Click on ‘Force send’
6. See error

mailing caught error Error: getaddrinfo ENOTFOUND smtp.example.com

Expected behavior To send email to mailtrap

I was able to get it to send within the main nextjs app by doing
dangerouslyForceDeliver: true inside sendMail

Any help would be appreciated
