Yup.
I'm also using
deny message = $sender_helo_name is my IP address
condition = ${if eq{$sender_helo_name}{$interface_address}{yes}{no}}
deny condition = ${if match
{${lc:$sender_helo_name}}{\N^(.*\.|)(DOMAINS)$\N}{1}{0}}
message = Do not pretend to be me, impostor
- where DOMAINS is a macro listing all "local" domain names. These these
checks are not executed for mails originating from our LAN of course...
