I have built rpms of SpamAssassin for Fedora 8, by backporting spamassassin-3.3.0-5.fc11.src.rpm from Fedora 11 and rebuilding with the latest available version.
You must install the following Perl modules from CPAN:
- IP::Country
- Net::Ident
- Encode::Detect
Update 2011-08-23: Added SpamAssassin 3.3.2.
