Dear David,

I discovered an issue related to the grav-admin module. The forgot password functionality (or any email notification) was not sending emails. The exception traceback routed the problem in the EHLO and HELO SMTP protocol commands resulting in a 501 (invalid domain address).

The nginx configuration /etc/nginx/conf.d/default.conf has a setting,

server_name _;

This should be changed to,

server_name $hostname;

After restarting the container, the email notifications began working as advertised.

I have a temporary solution in post-processing (which could be included in the Dockerfile):

sed -i 's/server_name.*/server_name $hostname;/' /etc/nginx/conf.d/default.conf

Thanks for the awesome docker. It's one of the few that's using the most recent version(s) (php + grav).

Cheers,

Hans
