Be very careful which blacklists you use. Most are utter rubbish and don't check what they list or offer enough information to actually be able to get support staff of the listed ISP to fix the problem. It's very annoying getting bounced because some over-zealous blacklist decided to include the whole hosting provider/hosting facility/ISP/uplink/country/world after one email to a honeypot address from a clueless person's web form or autoreply.
Yes, sorry I should of made that clearer, Like you I personally dislike most of the blacklist services out there. maybe they are ok to be used as a weighting on a rule filter but that's about it.
First off, the benefits of running your own server are, in my opinion, underrated. For example, I'm sitting in an office in Derby, typing this on my webmail (running on top of postfix) on a server that's sitting in my living room. I have total control and that makes me happy.
However, I disagree with your views on blacklists. For me, they have (almost totally) solved the spam problem. I haven't had a spam in over 2 months since I implemented blacklist blocking. I agree you have to be careful about which ones you use as some of them are too agressive, but if you are careful, they are an invaluable resource. I use blackhole.securitysage.com, rhsbl.sorbs.net, bl.sorbs.net, dnsbl.sorbs.net, and bl.spamcop.net. I regularly grep through my mail logs for rejections every time they roll over, and can honestly say that not one legitimate e-mail has been bounced. Particularly effective is dnsbl.sorbs.net which will not allow mail from dynamic IP ranges through and this seems to be where 90% of spam originates from through zombied Windows boxen.
