Remote mail server

I’m looking for a way to setup a remote smtp server for sending emails to users, I would need to specify username and password of the ‘no-reply’ account that will be used for sending emails. Is there a way to do that which I have overlooked?

That’s part of Rails’ default email infrastructure.
See smtp_settings on Rails Guides’ Action Mailer Basics.

I’m not sure if Foodsoft allows configuring this in config/app_config.yml too (I don’t think so).
