Is possible reject mail with multiple destination?

[kazabe]

Hi

My boss was request me to stop the mails related with non laborals contents.

Specifically wanna stop all the emails related with videos, jokes,
funny pictures, etc. We detect to any email with 12 or more address
destination in the body, always have non laboral content.

Is possible evaluate the body content to stop any email with 12 or
more forward addresses?

Thanks in advance.

why you want to stop email with 12 or more forward address. I think you should stop the email that has videos,jokes, funny pictures attachtments. To do that, you can set it in the admin console.
