First install the module from Postal Systems private registry:

`
$ npm install @postalsys/postfix-queue-parser
`

next import the postfixQueueParser function into your script:

`js
const { postfixQueueParser } = require('@postalsys/postfix-queue-parser');
`

If you have already built your application using the free version of postfix-queue-parser and do not want to modify require statements in your code, you can install the MIT-licensed version as an alias for "postfix-queue-parser".

`
$ npm install postfix-queue-parser@npm:@postalsys/postfix-queue-parser
`

This way you can keep using the old module name

`js
const { postfixQueueParser } = require('postfix-queue-parser');
`

- arrivalTime {Date} queue time
- sender {String} MAIL FROM address
- originalRecipient {String} RCPT TO address
