I'm a little late to this party, but…

Here's a couple of examples of well-known domains that "fail" my check:

   warn
     condition = ${if and{{def:sender_host_address}{!def:sender_host_name}}\
                       {yes}{no}}
     add_header = X-Host-Lookup-Failed: Reverse DNS lookup failed for 
$sender_host_address (${if eq{$host_lookup_failed}{1}{failed}{deferred}})



    cambridgejazz.org


    thegreatcourses.com


    localsecrets.com


    mbna.co.uk



and that includes real user account emails, not just marketing spam.


apols for the late reply.

cheers,
calum.
