Here is what I do. I have a script "rdnsbl.cmd" that builds my own RDNS BL list:
dnscmd \\your.dns.server /RecordAdd yourdomain.com.
*.%1.rdns.yourdomain.com. A 127.0.0.2
dnscmd \\your.dns.server /RecordAdd yourdomain.com.
%1.rdns.yourdomain.com. A 127.0.0.2
Submit all the spam domain names (e.g., spamdomain.com) with one line per
domain like this:
call rdnsbl spamdomain.com
Add the RDNSBL test to your Declude config file:
RDNSBL dnsbl %REVDNS%.rdns.yourdomain.com *
8 0
Enclosed is a zone file to get you started - obviously, you need to
customize to your OWN domain name where you want to host your RDNS BL.

Yes. The FROM address, the reverse DNS and the HELO all match the same
domain. They tend not to trip any tests unless the IPs have been reported
to Spamcop or another IP4R provider.
yourdomain.com.dns
