Method and system for optimized persistent messaging

A messaging method, comprising,

• receiving a message for delivery to a specified destination;
• determining from among a predefined universe of message delivery services, a first set of delivery services capable of delivering the message to the specified destination;
• generating a second, prioritized set of delivery services capable of delivering the message to the specified destination, wherein the second set of delivery services:
• includes a plurality of distinct delivery services;
• is a subset of the first set of delivery services;
• and
• is ordered in accordance with a set of prioritization criteria applicable to delivery of the message;
• storing the message, along with a representation of the second, prioritized set of delivery services, for utilization by a message delivery mechanism.

A computer program product for use in conjunction with a computer system, the computer program product comprising a computer readable storage medium and a computer program mechanism embedded therein, the computer program mechanism comprising:

• message receiving instructions for receiving a message for delivery to a specified destination and for storing the message in a message-in data structure;
• filtering instructions for determining from among a predefined universe of message delivery services, a set of delivery services capable of delivering the message to the specified destination;
• message delivery instructions for repeatedly performing a sequence of message delivery steps, the message delivery instructions comprising instructions for:
• (A) selecting a delivery service from the first set of delivery services for which a termination condition has not been established;
• (B) attempting to deliver the message to the specified destination using the selected delivery service;
• and
• (C) repeating the attempting when the attempting is not successful until a termination condition is achieved, the termination condition selected from the set consisting of successful delivery of the message and a predefined message delivery failure condition.

A messaging system, comprising:

• at least one processing unit for executing procedures containing executable instructions;
• memory, including a message-in data structure stored within the memory;
• a carrier database stored within the memory, the carrier database storing information about a predefined universe of message delivery services;
• wherein a processing unit of the at least one processing unit is configured to:
• receive a message for delivery to a specified destination and for storing the message in a message-in data structure;
• determine from the information in the carrier database concerning the predefined universe of message delivery services, a first set of delivery services capable of delivering the message to the specified destination;
• repeatedly perform a sequence of message delivery steps, the message delivery steps comprising:
• (A) selecting a delivery service from the set of delivery services for which a termination condition has not been established;
• (B) attempting to deliver the message to the specified destination using the selected delivery service;
• and
