Why am I receiving defer notification for reason of Recipient Verification Unavailable on my Barracuda Spam Firewall?

  • Type: Knowledgebase

Solution #00003765

Scope:
All Barracuda Spam Firewalls, All Firmware Versions.

Answer:
Please check to make sure you are not using a "catch-all" domain such as an asterisk ( * ). This causes the Barracuda recipient verification process to become unavailable for a short period of time. The verification process relies on an actual domain name to perform its job properly. Please change this to your actual domain name.
