21     When using the require_resolvable_fromhost plugin for qpsmtpd I noticed
22     that mails from user@localhost.localdomain was actually getting through
23     this filter. I finally found out that the plugin has a bug that causes it
24     to insert default search path if it cannot find the domain. This means in
25     my case that localhost.localdomain was then tried resolved as
26     localhost.localdomain.swerts-knudsen.dk and since I have a wilcard CNAME
27     was resolved as my public IP.
28    
29     Since this plugin is only enabled for public interface the fix is to set
30     the "dnsrch" flag when creating the Net::DNS object.
31    
32     In require_resolvable_fromhost:
33     my $res = Net::DNS::Resolver->new (
34     dnsrch => 0
35     );
