I've got Q2A running in a Docker container on an AWS EC2 instance. What additional work needs to be done past a base install in order to send mail to users? For example, if I want users to confirm their email before being able to make posts. I do not need the site to receive any emails, just the ability to send (please correct me if this is not the case)
I know there is an Emails section of the Admin page, but I feel like I am missing some SMTP server installation or something, as none of my changes on that page seem to make a difference.
When I send a test message to myself from Admin/Mailing, the page simply states "A server error occurred - please try again."
Do I need to install an SMTP server on my AWS instance to handle outgoing mail? Am I missing some part of the installation?
UPDATE: The container in which Q2A was hosted did not have the `sendmail` program installed. After installing, I no longer get the aforementioned "A server error has occurred," however now the page just hangs when I click "Send test to me." After a while, it claims to have sent a test message to my email, but I receive no email in any folders.
Still not sure what to do here...
