What does the "Numeric Value" Policy type do in Mimecast?

The "Numeric Value" Policy type in Mimecast is designed to apply to email content aggregately concerning its size. This policy allows organizations to manage the total size of email data being processed, ensuring they remain within acceptable limits and adhere to any legal or regulatory requirements regarding data retention and size.

By setting policies that monitor and control the aggregate size of email content, organizations can effectively mitigate risks associated with performance degradation, storage issues, and compliance violations. This is particularly important in environments handling large volumes of emails, where exceeding size thresholds may lead to disruptions in service or issues with data management.

The other options are more focused on different aspects of email management, such as frequency, recipient limits, or the overall count of emails, which do not align with the specific function of managing email size that the "Numeric Value" Policy type addresses.
