If this is sending email to your server, then the presence of your server on blacklists will not matter. Furthermore if you are not using blacklists either then it becomes a moot point anyway.
Unfortunately as the recipient your options are limited. You cannot do many diagnostics as you don’t even know if the message is getting to your server. Do you know what path the message takes? Does it go through an ISPs server, some other server?
