Threshold (1KB – 800 MB)

Enter the oversized file threshold and select KB or MB. If a file is larger than the threshold the file is passed or blocked depending on the Over– sized MMS Message setting. The web-based manager displays the allowed threshold range. The threshold maximum is 10% of the unit’s RAM.

MMS bulk email filtering options

You can use the MMS bulk email filtering options to detect and filter MM1 and MM4 message floods and duplicate messages. You can configure three thresholds that define a flood of message activity and three thresholds that define excessive duplicate messages. The configuration of each threshold includes the response actions for the threshold.

The configurable thresholds for each of the flood and duplicate sensors and must be enabled in sequence. For example, you can enable Flood Threshold 1 and Flood Threshold 2, but you cannot disable Flood Threshold 1 and enable Flood Threshold 2.

You can also add MSISDN to the bulk email filtering configuration and select a subset of the bulk email filtering options to applied to these individual MSISDNs.

You must first select MM1 and/or MM4 to detect excessive message duplicates. If excessive message duplicates are detected, the unit will perform the Duplicate Message Action for the specified duration.

You can configure three duplicate message thresholds and enable them with separate values and actions. They are labeled Duplicate Threshold 1 through 3 and must be enabled in sequence. For example, you can enable Duplicate Threshold 1 and Duplicate Threshold 2, but you cannot disable Duplicate Threshold 1 and enable Duplicate Threshold 2.

When traffic accepted by a security policy that contains an MMS profile with duplicate message configured receives MM1 or MM4 duplicate messages that match a threshold configured in the MMS protection profile, the unit performs the duplicate message action configured for the matching threshold.

You can configure three message flood thresholds and enable them with separate values and actions. They are labeled Flood Threshold 1 through 3 and must be enabled in sequence. For example, you can enable Flood Threshold 1 and Flood Threshold 2, but you cannot disable Flood Threshold 1 and enable Flood Threshold 2.

When traffic accepted by a security policy that contains an MMS protection profile with message flooding configured experiences MM1 or MM4 message flooding that matches a threshold configured in the MMS profile, the unit performs the message flood action configured for the matching threshold.
