Spammer is spoofing a prior employees email for mass email campaignes and I receive 10000-50000 non delivery reports a day due to it

Is there anything I can do to stop the huge amout of traffic this has created on our server:
The problem is, some spammer spoofed a prior employee user on a mass email campaign. These emails in most cases are sent back to us as non delivery reports or worse 'f*** you spammer' emails. Our server has no current user in AD for this recipient anymore and responds back to them with a non delivery report which has since been suspended. The traffic generated and bandwidth used is unpresidented. Each day brings a different email spam campaign. As a result, the volume on our server is to much causing email bouncebacks and 1-3 hour lag times and its getting worse. Our clients and customers are also getting boucebacks when attempting to email us due to the volume.
