My goal is to get the PHP mail() function to work on Amazon Linux. So the best option seems to be to install msmtp (found in EPEL repository) but I get a dependency error.
I run run sudo yum --enablerepo=epel install msmtp but then get:
Loaded plugins: priorities, update-motd, upgrade-helper
1053 packages excluded due to repository priority protections

These are the details of the Amazon Linux instance:
NAME="Amazon Linux AMI"
VERSION="2018.03"
ID="amzn"
ID_LIKE="rhel fedora"
VERSION_ID="2018.03"
According to /etc/yum.repos.d/epel.repo it uses EPEL 6.
