body_checks Filtering Problem

[terenceconan]

Hello, everyone.

I got a filtering problem.
I have few mail domains in my mail server.
A mail domain have a spam problem.
They received a lot of virus zip files and requested me to block all zip attachment.
However, if i blocked all zip attachment in body_checks, all mail domains in mail server will also cannot receive zip attachment.
Is there a way only block all zip attachment in certain mail domain?
