Trying to get Spam URI Realtime Blocklist (SURBL) working with SpamAssassin 2.63 on RedHat Enterprise Linux 3 is a bit of a challenge. The plugin to make it work is spamcopuri which requires perl-URI-1.28 (or greater?). RHEL3 comes with perl-URI-1.21, we need to find a more recent RPM to rebuild. Fedora seems to be a pretty good starting point and they have 1.30 in the latest test release. After rebuilding that SRPM (with rpmbuild –rebuild), the build seems to go fine. More testing to come.

Update: Install is just as easy as it claims, copy the config file into the same directory as local.cf and restart spamd. And it starts tagging spam….
