Why does adding an RBL exemption cause a timeout on my Email Security Gateway?

Solution #00003699



All Email Security Gateways, all firmware versions.

When adding an RBL exemption to the Block/Accept > IP Reputation page, the web interface may time out. This happens when the Email Security Gateway attempts to submit the exemption to Barracuda Networks via email but is unsuccessful; such behavior presents itself when the two following conditions are true:

  • You have entered either a problematic or an incorrect Outbound SMTP Host/Smart Host on the Basic > Administration page.
  • You have enabled Submit RBL Exemptions to Barracuda Networks on the Block/Accept > IP Reputation page. 
To resolve the timeout error, either remove the Outbound SMTP Host/Smart Host, or disable Submit RBL Exemptions to Barracuda Networks.
