You can configure additional Anti-Spam and Anti-Phishing analysis settings, such as time- or size-based scanning restrictions, and spam analysis of Microsoft Office files attached to messages.
To configure time- or size-based Anti-Spam and Anti-Phishing scanning restrictions:
- Perform the following steps in the Management Console tree:
- To configure Anti-Spam and Anti-Phishing scanning restrictions for an unassigned Security Server, maximize the node of the relevant Security Server
- To configure Anti-Spam and Anti-Phishing scanning restrictions for Security Servers belonging to a profile, maximize the Profiles node and inside it maximize the node of the profile for whose Security Servers you want to configure Anti-Spam and Anti-Phishing scanning restrictions.
- Select the Server protection node.
- In the workspace, on the Protection for the Transport Hub role tab, expand the Advanced settings of Anti-Spam configuration section.
- In the Restrictions section, use the Maximum time for scanning a message spin box to specify the necessary value in seconds.
If the message scan duration exceeds the specified time, the Anti-Spam or Anti-Phishing scan of the message stops. The default value is 60 sec. If the application is configured to add service headers to the message, they will contain information to the effect that the maximum scan time has been exceeded.
- In the Restrictions configuration section, use the Maximum object size to scan spin box to specify the necessary value in kilobytes.
If the message with all attachments exceeds the specified size, Anti-Spam and Anti-Phishing scanning is not performed, and the message is delivered to the recipient. The default value is 1,536 KB (1.5 MB). The maximum value is 2096128 KB (2047 MB), and the minimum value is 1 KB. If the application is configured to add service headers to the message, they will contain information to the effect that the maximum object size has been exceeded.
