This past week I encountered a customer issue, which occurs on a fairly regular basis. The customer’s secure email gateway, a Barracuda Spam & Virus Firewall, was blocking emails from an external sender based on reputation analysis. As you can guess, the sender was not too happy about this. In this particular case, the sender’s IP address was blocked because spam was detected from it. This could be due to a number of reasons, which may include an internal compromised system generating spam or unintentional spamming by the sender.
This brings up the fact that, in today’s computing environment, IT departments can no longer assume that the internal networks are secure and free from malware. The use of outbound email filtering protects an organization on two fronts - prevents the organization’s IP addresses from getting on block lists, and prevents sensitive data in emails from leaving the organization. Delay in detecting that your organization is on a block list can cause frustration and disrupt business. Plus removal from a block list takes time. Furthermore, for compliance with industry or government regulations, emails with customer confidential information need to be protected. This means blocking such emails or enforcing encryption.
I’d like to share a brief case study below of a customer who has already seen the benefits of using outbound email filtering on the Barracuda Spam & Virus Firewall.

Coming back to the customer issue, the sending organization could have avoided getting on the block list if it had deployed outbound email filtering.
