Greetings. I'm seeking clarification on use of the "-r" option of
rblsmtpd, described here:
http://cr.yp.to/ucspi-tcp/rblsmtpd.html
The issue at hand is whether or not you can specify multiple blackhole
lists with one call, or if you have to chain calls to rblsmtpd.
I've had some reports that you can use multiple -r's, e.g.
rblsmtpd -rrelays.orbs.org -rrbl.maps.vix.com
However, user Mike Silbersack had a different experience and did some
further research into the issue and sent me this:

I think this would indicate that repeating use of -r wouldn't work as
expected.
Can anyone clarify what's really supposed to happen, what really
does happen, and what it all means in a larger existential context?
Thanks,
