The OP wrote he's already doing that, so I skipped that rules:

Block EHLO [my.ip.add.ress]:

condition = ${if eq {[$interface_address]}{$sender_helo_name}}
condition = ${if !eq {$interface_address}{$sender_host_address}}

Block EHLO my.dom.ain:

condition = ${if !eq {$interface_address}{$sender_host_address}}
condition = ${if match_domain {$sender_helo_name}{+local_domains}}
