Solution Overview

Problem

Current email routing systems face inefficiencies and increased bandwidth usage due to emails being sent to multiple accounts of the same person, leading to network congestion and administrative challenges, as existing solutions either require increased hardware costs or fail to effectively manage email routing based on user preferences.

Innovation Solution

Implementing a server-level email routing system that queries incoming emails against set preferences, allowing for conditional routing actions such as directing emails to specific accounts based on sender, receiver, domain, subject, or content, thereby reducing unnecessary data traffic and improving email management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If emails are sent to multiple email accounts of the same person, then the email delivery coverage is improved, but the network bandwidth usage increases and network congestion occurs

Engineering Contradiction:
Improveemail delivery coverageVSAvoidnetwork bandwidth usage
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The system performs preliminary routing analysis at the mail server before emails are transmitted across the network. By querying the routing application and determining the optimal destination email account in advance, the system prevents duplicate email transmissions to multiple accounts of the same person, thereby reducing network bandwidth usage while ensuring reliable delivery to the appropriate account.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The routing application acts as an intermediary between the mail server and email accounts. It receives routing requests from the mail server, queries the email system to determine the correct destination account based on user preferences and email characteristics, and returns the routing decision. This intermediary layer enables intelligent email routing that balances delivery reliability with network efficiency.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If server-level routing analysis is implemented, then email routing efficiency is improved, but the server processing load increases

Engineering Contradiction:
Improveemail routing efficiencyVSAvoidserver processing load
Core Design Contradiction:
ProductivityVSPower

Solution Approach 1:

The system implements partial routing analysis by querying only necessary email attributes (such as sender, recipient, subject, or content based on configured preferences) rather than performing complete email content analysis for every message. This selective querying approach improves routing efficiency while keeping server processing load manageable by avoiding excessive analysis of all email components.

Inventive Principle:
Principle #16Partial or excessive action

3Measurement precision

If user preferences are stored and queried for routing decisions, then email routing accuracy is improved, but the system complexity increases

Engineering Contradiction:
Improverouting accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

User routing preferences are stored in advance in the email system, allowing the routing application to quickly query and apply pre-defined routing rules without complex real-time decision-making. This preliminary setup of routing preferences enables accurate email routing based on user specifications while keeping the system complexity manageable through structured, pre-configured rules.

Inventive Principle:
Principle #10Preliminary action

AI summary

Methods, systems, and media are disclosed for managing the routing of an email at the server level to an email client by preferences set in a routing application located on the server. One embodiment includes querying, by a routing application located on a server and associated with an email system, the email by comparison to conditions for each preference set in the routing application, wherein a preference comprises a routing action. Further, the method includes identifying, based on the querying and by the routing application, a match between the email and at least one of the conditions. Further still, the method includes performing, based on the match and by the routing application, the preference associated with the at least one of the conditions of the email, whereby the email is transmitted to an email client.
