Do we want to support Email/Contact?

Or documenting on how to link your Drupal container to an mail container.

See docker-library/wordpress#30 for a very closely related discussion. The TL;DR is that it's hard to configure this in such a way that it's sane-by-default for most use cases, so I think documenting how to configure it might be a safer solution overall.

Documenting a good way to get around the issue would be great, as this function is also needed for password recovery for example...

After failing to link the sendmail to this one, I went with the smtp auth drupal module to be able to send email from another server. Uneleguant solution that I would roll back as soon as someone can document how to send mail from a linked container (or adds the functionality to this one).

Simple solution - extend the Drupal image with a custom Dockerfile and add SSMTP:

Dockerfile:

# Inherit from the Drupal 8 image.
FROM drupal:8

# Install SSMTP.
RUN apt-get install -y ssmtp

I also add configuration to SSMTP to relay through AWS SES or Mandrill, but I think the above works without anything extra.

I don't think there's a good generic solution we can apply here, but https://www.drupal.org/docs/develop/local-server-setup/managing-mail-handling-for-development-or-testing does have some good ideas, including pointers to https://www.drupal.org/project/smtp and https://www.drupal.org/project/phpmailer_smtp, one of which is definitely what I'd be using to solve this if I were running Drupal in my environment (either should be able to SMTP to a sidecar exim4 or otherwise container just as well as it can SMTP to an external provider).

Another option is something like ssmtp (as mentioned), but as ssmtp is technically deprecated I'd probably suggest msmtp instead.

Agreed. I am closing this issue.

For reference, if you want mailhog to intercept all emails, you can install mhsendmail
