Stacking multiple services in one container is an anti-Docker pattern

[szepeviktor]

Docker suggests you to run 1 service per container.

- SSL termination - web server - PHP-FPM
\ SMTP server

If you want to run a monolith why not do it in an operating system and keep it as clean as a container?

I suspect msmtp-mta is in the container to support mail(); in poorly written applications...

This is related to #15.

I see where Docker is coming from on this, but unfortunately for simple apps, php-fpm + nginx is required. And the only way to get this to work was to use supervisor (at the time).

Hoping S6 will make this less crappy 😁

S6 even talks about this: https://github.com/just-containers/s6-overlay#the-docker-way

Yup, poor applications like WordPress 🙃 Also MSMTP allows the ability for:

• DKIM signing
• Easy routing between "production email" or trapping everything in Mailhog

Web applications is production should use a transactional email service provider.
At least in viktor-world they do.
See number 6! https://github.com/szepeviktor/debian-server-tools/blob/master/Onboarding.md#specialized-infrastructure-providers

WordPress likes to have https://wordpress.org/plugins/smtp-uri/ installed where you can configure it with a single string.
