How to Install sSMTP on CentOS 8 AppStream

I have used the sSMTP package on CentOS 7 to send root emails to my Gmail address using an external mail server. However, the package isn't officially available for CentOS 8 in the EPEL 8 repo. Can it be installed on this OS like installing from the source? I assume that the source code is available on GitHub . I'm a novice about Linux so if it is possible then clear step-by-step instructions would be most helpful. Thank you
