It shouldn't. Dan has complete instructions on what to look for when
upgrading from previous versions at http://cr.yp.to/ucspi-tcp/upgrade.html .
You may want to install a patch to rblsmtpd at the same time which allows it
to work with A records instead of the TXT records, as some of the list
providers eliminated the TXT records to save space. You can find the patch
from a link at qmail.org.

They're not so much "false" positives as they are simple blocks of domains
which also send legitimate mail -- that's the nature of the beast. Very few
spam relays are used _only_ as spam relays.
If you want a better chance of not blocking mail you care about, perhaps start
with the DUL (dialup list). It only lists the IP addresses which ISPs have
voluntarily submitted as belonging to dialup lines, and which therefore
shouldn't be sending mail directly anyways.
