What blacklists are you using at your MTA?

I'm curious what blacklists other people are currently using at their MTA,
rejecting during delivery, before mail gets to spamassassin.
For a while I've been using zen.spamhaus.org and dnsbl.sorbs.net. Based on
recent stats ( http://ruleqa.spamassassin.org/?daterev=20110319 )
I think I'm dropping sorbs and adding psbl.surriel.com.
MSECS SPAM% HAM% S/O RANK SCORE NAME WHO/AGE
0 0.7411 4.1503 0.152 0.31 (n/a) __RCVD_IN_ZEN
0 0.3626 5.1060 0.066 0.24 (n/a) __RCVD_IN_SORBS
0 49.8989 0.0183 1.000 0.97 0.00 RCVD_IN_PSBL
Man it's a shame those __* rules don't include all their sub-rules.
Why do some RBLs use firsttrusted and others use lastexternal? Shouldn't
they all be the same?
zen.spamhaus.org:
MSECS SPAM% HAM% S/O RANK SCORE NAME WHO/AGE
0 70.7263 0.0016 1.000 1.00 0.00 RCVD_IN_XBL
0 65.6389 0.1020 0.998 0.90 0.00 RCVD_IN_PBL
How can those add up to more than 100% of spam? They're both checking
lastexternal, for different values?
Also includes:
0 0.5502 0.0469 0.921 0.65 0.00 RCVD_IN_SBL
dnsbl.sorbs.net:
MSECS SPAM% HAM% S/O RANK SCORE NAME WHO/AGE
0 15.4739 0.1462 0.991 0.81 0.00 RCVD_IN_SORBS_DUL
0 10.8966 0.1608 0.985 0.78 0.00 RCVD_IN_SORBS_WEB
0 0.1347 0.0027 0.980 0.58 0.00 RCVD_IN_SORBS_SOCKS
0 0.1347 0.0027 0.980 0.58 0.00 RCVD_IN_SORBS_HTTP
0 0 0 0.500 0.48 0.00 RCVD_IN_SORBS_ZOMBIE
0 0 0 0.500 0.48 0.00 RCVD_IN_SORBS_BLOCK
0 0 0 0.500 0.48 0.00 RCVD_IN_SORBS_SMTP
0 0.0005 0.0005 0.458 0.48 0.00 RCVD_IN_SORBS_MISC
TOTAL 26.6404 0.3129 0.998
And psbl.surriel.com is just:
MSECS SPAM% HAM% S/O RANK SCORE NAME WHO/AGE
0 49.8989 0.0183 1.000 0.97 0.00 RCVD_IN_PSBL
If I have the sorbs totals right, psbl is *way* better than sorbs, both in
ham% and spam% hit.
