smart people would have opened koji, enter spamasssin,, select the F31 package from https://koji.fedoraproject.org/koji/packageinfo?packageID=554 and downloaded https://kojipkgs.fedoraproject.org//packages/spamassassin/3.4.4/1.fc31/x86_64/spamassassin-3.4.4-1.fc31.x86_64.rpm or just used "dnf --enablerepo=updates-testing upgrade spamassassin"
I package a few plugins of my own for installation on other systems, not sure why it is necessary to use personal adjectives. Sorry this question had to irk some sensibilities.
Cheers
