It's possible, but it would require running the container in a privileged mode. It would essentially mitigate any security benefit you get from running the MTA in containers. I would recommend copying all of these files into a directory in /srv dedicated to the service (in this case the MTA). For example, I would create a directory structure something like: /srv/mail.example.com/etc/passwd /srv/mail.example.com/etc/shadow /srv/mail.example.com/etc/etc/group /srv/mail.example.com/etc/etc/gshadow /srv/mail.example.com/etc/home/user/Maildir Then, I would bind mount each of these in. This is what I do for Mediawiki, MySQL, and Wordpress. Sadly, I don't think I've created a GitHub repo to show people how to do it. Personally, I also run systemd in the container (because I hate reverse engineering startup scripts) and I run the whole thing read-only. IMHO, thisngives me a balance of security and convenience. If you don't run systemd, you could even run rootless. Best Regards Scott M On Sun, Mar 22, 2020, 9:18 PM Philip Rhoades <phil@pricom.com.au> wrote:
People,
I want to have a MTA running from a container but is it possible for the containerised MTA:
1. to deliver mails to users on the host's file system dir (eg /home/user/Maildir)?
2. to have access to the host's:
/etc/passwd /etc/shadow /etc/group /etc/gshadow
files for users who are logging in to the host to look at their mails?
Thanks,
