Hi

We have a customer, which got about 2000 Mails in the last 2 days and he is getting even more, because someone is using his mail address as a reply address for spam mails.

Unfortunatley the spamer is using the system mail address for this account, which is username@servername.serverdomain.com

So we can not use :blackhole: or the SPAM blocker in the cpanel, because there we can only block mails which belongs to his account.

How can I block mails which are comming to this account?

Thanks
Michael
