Of course it can; Exim is very flexible. How to do this is in the
documentation.
However, doing so would be a long-term disservice to the
reliability of email. By not accepting null-sender mail
this site make it impossible to send them Delivery Status
Notifications ("bounces"), meaning that when you (or anyone)
has a problem delivering a mail you have accepted from
them, on behalf of one of their customers, you *cannot*
inform them by the usual standardized method.
Carry on encouraging them to change. Make the point that
refusing to accept bounces is also symptomatic of a
full-time spammer or compromised system.
