each to our own, I dont consider they give many false positives at all,
not in this part of the world, but of course it may be different for
where you are, however even with the acceptable FP's they *may* give,
the massive reduction in spam makes it completely worth it.
The more they hit there, the less work MailScanner has to do, it can use
system resources just to scan for viruses and phishing and of course
whatever spam it detects that get past the RBL's :-)

Don't use these to reject connections at SMTP level, they give many

increase the spam score.
zen.spamhaus.org and list.dsbl.org, au contraire, are much better
choices for rblsmtpd.
A good thing to do as well which also dramatically reduces spam, is
enforce DNS forward and reverse, if someone can't be bothered making
sure their mail server is RFC compliant, then I am under no obligation
to allow my servers to accept connections from them.
