For anyone wanting an RPM of the latest pop-before-smtp release, it's easy to do it yourself by running this command:
rpmbuild -ta pop-before-smtp-1.39.tar.gz
If you're running that as non-root, you can create your own rpm build area like this:
cd $HOME
mkdir -p rpm/{SPECS,BUILD,SRPMS,RPMS}
echo %_topdir $HOME/rpm >.rpmmacros
and then run the rpmbuild command above. You'll find the noarch rpm down in the ~/rpm/RPMS/noarch dir.
