Sendmail support?

[iamkobold]

Seems like having baked in sendmail support that goes to the docker host would be nice to have as part of the main image.

Sendmail is a common if not required part of Rails environments and being able to have a nice consistent way to have the docker rails environment send to the host would be nice. Or at the very least, providing some documentation on how to configure this image for sendmail to the host.

This would be a nice improvement, maybe ssmtp could be used?

I would like to ask for this enhancement too

As a customer (not contributor/maintainer), I vote against this. I feel the image is already really large (I don't want SSH or cron on my rails servers) and this would increase the weight.

For mailer use, we connect ActionMailer directly to an SMPT service (e.g. SendGrid) and don't need sendmail or other MTA installed on the image.

I also vote against this, the images are already rather large.
