I still have production servers running 2.63 - how can I add SURBL to them? Just go to CPAN and install "Mail::SpamCopURI" on those machines? (Yes, they will be migrated to 3.0.1 once my Testbed machine is working properly)
I don't know if it's on CPAN or not, but if it isn't you can always download the tarball and install it that way... The sourceforge project is linked in the "links" section on surbl.org.
