Hi Guys, I am getting the below bounce back when I send emails with to 2 of my clients with cyberoam firewalls. Diagnostic-Code: SMTP; 550 Cyberoam Anti Spam has blocked this email because the sender's IP Address is blacklisted. I have checked my IP and it is not listed on any blacklist database. How can do I go about this. -- Regards, C . K
