After testing ssmtp, nullmailer, and msmtp for relay-only outgoing mail on Fedora #Linux. Here's my final report:

- ssmtp is packaged for Fedora and I got it working, but the Ansible role I found for it had been abandoned by the author because ssmtp itself is unmaintained.
- nullmailer might have worked, but is not packaged for Fedora.
- msmtp worked. I used this Ansible role, after patching it to work on Fedora: https://github.com/chriswayg/ansible-msmtp-mailer
