I am having an issue with socketmail.
Socketmail requires to have all emails sent to none existing users on the domain name to be sent to [email protected]
But when spammers are sending an email to none existing Socketmail user(no such a user in socketmail) its delivered to default account and then its baunced and if the bounced address doesnt exist you are getting such a message
"Hi. This is the qmail-send program at server.agency.info.
I tried to deliver a bounce message to this address, but the bounce bounced!"

and those messages are delivered to default admin account.

Any ideas on how to make it so it dont baunce the messages to none existing users ?
