as Steve mentioned, can you try to include @IP in NAME::lookup instead of using local bind?

e.g. 

[root@ve10:Active] config  b virtual bar list
virtual bar {
   snat automap
   destination 172.28.19.252:80
   ip protocol 6
   rules myrule
   profiles {
      http {}
      tcp {}
   }
}
[root@ve10:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
   log local0. "--"
   HTTP::collect
   HTTP::header replace Host "www.youramigo.com"
   NAME::lookup @8.8.8.8 www.youramigo.com
}
when NAME_RESOLVED {
   log local0. "--"
   node [NAME::response address 0] 80
   HTTP::release
}
when HTTP_RESPONSE {
   log local0. "--"
   log local0. "server [IP::server_addr]:[TCP::server_port] | status [HTTP::status]"
}
}

 client

[root@centos251 ~] curl -I http://172.28.19.252/
