In case it makes you feel better: my *own* address was on the 510sg list
for awhile last month. But I still use the list ;-). Nothing to stop
you from using some less-aggressive list though; see
http://relays.osirusoft.com/ for links to a dozen or more possibilities.
In practice, any DNSBL list can cause denial-of-service problems.
(The original and still most conservatively run one, MAPS RBL, had a
memorable episode where someone put 127.0.0.1 into the blacklist for
a few hours...) I deal with this by installing local whitelist
exceptions for people I talk to regularly. Otherwise, there's always
the mailing lists.
