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

failure notice

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
