Ok, here he is again, the guy with the twenty questions. :) Seriously,
though, I apologize for all the questions, but this one really confuses me
again.
Examining the guess_mechs, default,
guess_mechs => "a/24 mx/24 ptr exists:%{d}.wl.trusted-forwarder.org"
I implemented it, because it seemed useful. Running in debug mode, with an
invalid IP address, but within the /24 subnet, I followed the audit trail:
myquery: 50.160.109.194.in-addr.arpa PTR failed: NXDOMAIN.
evaluate_mechanism: +exists(%{d}.wl.trusted-forwarder.org) \
for domain=asarian-host.net
macro_substitute: %{d}.wl.trusted-forwarder.org -> \
asarian-host.net.wl.trusted-forwarder.org
looking up asarian-host.net.wl.trusted-forwarder.org
Whoa! What's with parsing the DOMAIN NAME? I understood
wl.trusted-forwarder.org to contain regular in-addr-arpa style entries;
like:
13.197.135.66.wl.trusted-forwarder.org (66.135.197.13 = mxpool07.ebay.com)
Especially since mxpool07.ebay.com.wl.trusted-forwarder.org, as expected,
does NOT resolve (and the in-addr-arpa query DOES). So, should
"exists:%{d}.wl.trusted-forwarder.org" not be
"exists:%{ir}.wl.trusted-forwarder.org"?
