摘要:
The present invention provides for generating inputs that can be provided to a message classification module to facilitate more reliable classification of electronic messages, such as, for example, as unwanted and/or unsolicited. In one embodiment, a sending messaging server provides an appropriate response to address verification data thereby indicating a reduced likelihood of the sending messaging server using a forged network address. In another embodiment, it is determined if a messaging server is authorized to send electronic messages for a domain. In yet another embodiment, electronic message transmission policies adhered to by a domain are identified. In yet a further embodiment, a sending computer system expends computational resources to solve a computational puzzle and includes an answer document in an electronic message. A receiving computer system receives the electronic message and verifies the answer document.

Techniques are provided for determining a schedule for performing tasks. Each of the tasks to be scheduled is registered. The schedule includes tasks to be performed for a plurality of devices using at least one shared resource. The schedule is determined for performing the tasks in accordance with resources used by each of the tasks and in accordance with usage patterns of the plurality of devices. An inquiry is made as to whether to commence performance of a task at an associated scheduled time in accordance with the schedule. A scheduler determines whether one or more resources used by said task are available. If the determining step determines that the one or more resources are not available, rescheduling the task to be performed at another time.
摘要:
An object system provides composable object execution environment extensions with an object model that defines a framework with contexts, policies, policy makers and activators that act as object creation-time, reference creation-time and call-time event sinks to provide processing of effects specific to the environment extensions. At object creation time, an object instantiation service of the object system delegates to the activators to establish a context in which the object is created. The context contains context properties that represent particular of the composable environment extensions in which the object is to execute. The context properties also can act as policy makers that contribute policies to an optimized policy set for references that cross context boundaries. The policies in such optimized sets are issued policy events on calls across the context boundary to process effects of switching between the environment extensions of the two contexts.
