Email address spoofing

Is there anything to do against email address spoofing ? Many of our
customers have their email address spoofed. Then they receive a sh*t
load of bounce:
Mail delivery failed: returning message to sender
Delivery Status Notification (Failure)
Undeliverable: 73% off for steve.messner
Returned mail: see transcript for details
My antispam gateway stops 80% of them but the customers receives like 10
of these / minutes. Another result of these bounce is my server being
overloaded which lead to greater delay for mail scanning.
Can I do something against that ?
Thanks in advance
