Sender Policy Framework (SPF) is a widely used method of distinguishing authorized email from unauthorized email. SPF policies are published into a domain's DNS and then looked up and evaluated by mail receivers. Due to the complexity and limitations of the SPF specification, implementation mistakes and risks are widespread. This problem is compounded by the common practice of nesting SPF policies which introduces hidden risks, particularly exceeding DNS lookup limits. Embodiments of the present disclosure enable new SPF techniques such as selectively inactivating parts of a policy by introducing a virtual-all term, designed to secure against the third-party term inclusions in the policy. When the primary policy is online, the virtual-all term may serve as a terminate policy evaluation much like a traditional “all” term. If the primary policy is offline, a “fail open” may be produced, allowing policy evaluation to proceed into previously inactivated segment of the policy.

Systems and methods are disclosed to implement a machine learned system to determine the comparative relationship between item package quantity (IPQ) information indicated in two item descriptions. In embodiments, the system employs a neural network that includes a token encoding layer, an attribute summarizing layer, and a comparison layer. The token encoding layer accepts an item description as a token sequence and encodes the tokens with token attributes that are relevant to IPQ extraction. The attribute summarizing layer uses a convolutional neural network to generate a set of fixed-size feature vectors for each encoded token sequence. All feature vectors for both item descriptions are then provided to the comparison layer to generate the IPQ comparison result. Advantageously, the disclosed neural network model can be trained to make accurate predictions about the IPQ relationship of the two item descriptions using a small set of token-level attributes as input signals.
