Intermediary Service Sender Address Segmentation for Notification Routing

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Intermediary services face challenges in efficiently notifying users of misdirected responses associated with messages sent on their behalf, as current spam and malware filtering systems block messages with sender addresses that differ from the actual sending domain, leading to lost notifications and misdirected communications.

Innovation Solution

Assigning a unique sender address with message delivery system domain data to messages, ensuring notifications are first delivered to the message system domain, and then mapping user identification data to a user notification routing address for correct delivery to the user.

1Object-affected harmful factors

If spam filtering systems block messages with sender addresses that differ from the actual sending domain, then spam messages are filtered effectively, but legitimate messages sent through intermediary services are also blocked

Engineering Contradiction:

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The system segments the sender address into two distinct parts: the actual sending domain (used for spam filtering) and the user identification data (used for notification routing). This allows the message to be filtered based on the sending domain while preserving the user's address for notification purposes, resolving the contradiction between spam filtering and legitimate message delivery.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system introduces an intermediary notification system that receives misdirected responses at the sending domain and forwards them to the user's actual address. This intermediary layer allows spam filters to block messages at the domain level while ensuring users still receive notifications through the intermediary forwarding mechanism.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If the intermediary service's sender address is used in the From field, then messages can be sent through the message delivery system, but notifications of misdirected responses are routed to the intermediary service instead of the user

Engineering Contradiction:

Improvemessage delivery capabilityVSAvoidnotification delivery accuracy

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The sender address is segmented to include both the message delivery system domain (for routing messages through the intermediary service) and user identification data (for accurate notification delivery). This segmentation allows the system to maintain message delivery capability while ensuring notifications reach the correct user.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system implements a feedback mechanism where misdirected responses sent to the From field are captured by the notification system, which then forwards them to the user's actual address. This feedback loop ensures that users receive notifications of misdirected responses even when the From field contains the intermediary service's address.

Inventive Principle:

Principle #23Feedback

3Loss of information

If the user's routing address is used in the From field, then notifications are delivered to the user, but spam filters block the message as coming from a different domain

Engineering Contradiction:

Improvenotification delivery accuracyVSAvoidspam filtering block

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The system segments the sender address information into the actual sending domain (placed in the From field to pass spam filters) and the user identification data (used internally for notification routing). This allows the message to bypass spam filters while ensuring notifications are delivered to the user through the segmented user identification component.

AI summary

Messages sent on behalf of a user through an intermediary service message are assigned a unique sender address including unique message identification data unique to each message being sent. The unique sender address further includes message delivery system domain data identifying the actual domain of the intermediary service. The unique message identification data is also mapped to a user routing address. The unique sender address is then used to populate the “From” field of the message. Consequently, any message response sent to the “From” field of the message can be automatically analyzed to identify the user identification data in the unique sender address and automatically mapped to the user notification routing address. A notification of the response message can then be automatically relayed to the user using the user notification routing address.
