no ISP will do this, because of the big time cost lawyers will take
them up on for something occuring as frequently as spam, and is as
difficult to track down.  what does the spammer do?  he doesn't give
his real name or address, so that ISP would sit and only pay the
lawyer.

regarding a way to find out:  there's a program out there called
"rblcheck", you can compile in a default list of RBLs and/or feed it
appropriate options.  it doesn't do much more than a DNS query for A
or TXT records on a specific IP, so you could propably do it yourself,
like so (djbdns):

dnsq any <your-IP-reversed>.rbl.dom [rbl-dns-server]

where the rbl-parts are specific to the rbl-provider.  i just checked
my own ip, and the logs reveil what rblcheck did:

tx 0 1 150.125.226.62.formmail.relays.monkeys.com. relays.monkeys.com.

the answer being:

2002-08-27 16:15:34.433477500 nxdomain 83d31c30 3600
                              150.125.226.62.formmail.relays.monkeys.com.

rblcheck is easier to use:

#rblcheck -h
rblcheck 1.5
