bokysan/docker-postfix v1.2.0

Add SMTP_HEADER_CHECKS and ALLOW_EMPTY_SENDER_DOMAINS

on GitHub

Three new exiting features in this release:

• Allow setting empty sender domains from PR #17
• Add SMTP_HEADER_CHECKS from PR #15
• A script to build the image with custom alpine version from PR #20

One important feature: Multi-platform build (Yay!)

This release switches from Docker hub build to GitHub Actions. These allow us to use docker buildx. As a result, this image is available for more platforms than ever:

• linux/386
• linux/amd64
• linux/arm/v6
• linux/arm/v7
• linux/arm64
• linux/ppc64le

Just use the image as standard - boky/postfix:latest - docker will do the rest
