Postal vs Postfix: What are the differences?

Developers describe Postal as "Open source mail delivery platform, alternative to Mailgun or Sendgrid". Postal is a complete and fully featured mail server for use by websites & web servers. Think Sendgrid, Mailgun or Postmark but open source and ready for you to run on your own servers. Postal was developed by aTech Media to serve its own mail processing requirements and we have since decided that it should be released as an open source project for the community. On the other hand, Postfix is detailed as "A free and open-source mail transfer agent". It is a free and open-source mail transfer agent that routes and delivers electronic mail. It is Wietse Venema's mail server that started life at IBM research as an alternative to the widely-used Sendmail program. Now at Google, Wietse continues to support it.

Postal and Postfix can be categorized as "Transactional Email" tools.

Postal is an open source tool with 9.02K GitHub stars and 534 GitHub forks. Here's a link to Postal's open source repository on GitHub.
