Sounds like a lot of work for an old spamassassin version.

Hi, I've backported 3.4.0 from Ubuntu 14.04 TLS for Ubuntu 12.04 LTS (perl 5.14.2), which comes with very old version 3.3.2 (can't upgrade the complete host right now). Before installing it: is there anything to be aware of, beside better wiping bayes database and starting fresh?
