Firstly thanks for this, I found your image super helpful in moving to a dockerised postfix.

I was wondering if you had any ideas for how to get cron on the host machine to use this? I've got ports 25 and 587 mapped to the host, but cron seems to want a sendmail command, which is normally provided by postfix. It seems crazy and potentially very confusing to install postfix on the host machine just to get sendmail, and it's going to conflict with the mapped ports.

I tried minimalist options like msmtp but then I end up with bare or invalid from headers like From: root or From: root (Cron Daemon) and the mail gets rejected.

Do you have any suggestions for how to set this up sanely?

Hello!

Can you provide an example of what a customer configuration script might look for this image? Thanks!
