Hi All, My server CentOS 4, Sendmail, MailScanner (SA & ClamAV) is being buried by spoofed emails that are bounced back to my domain by the recipient's servers. Virtually all these emails are being sent from a zombie at a single IP. i.e.: All the messages contain the following line somewhere within: Received: from d04m-89-83-98-193.d4.club-internet.fr ([89.83.98.193])
