Resolution

Product: Email Security.cloud
Feature: Outlook email submission add-in
Submission Type: False Negative, an email containing spam or malicious code that was incorrectly identified as being clean of security threats.

The Email Submission service enables an email user to mark an email as spam or malware threat when using the Symantec Outlook Email Submission add-in for the Email Security.cloud services. These submissions help Symantec to improve the effectiveness of spam filtering as well as malware filtering by creating appropriate rulesets.
