Email Sender Address Verification and Warning Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication apparatuses face challenges in transmitting emails without being misinterpreted as spoofing attempts, leading to potential email rejection or correction by email providers.
Innovation Solution
A communication apparatus with a display and controllers that manage email transmission based on user input, providing options to select between two modes of email transmission and displaying warnings or options for verifying email delivery when the sender's email address differs from the login email address.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the email address of the sender is set in the sender field, then the email transmission flexibility is improved, but the email may be misinterpreted as a spoofing attempt and rejected
Solution Approach 1:
The system performs preliminary verification by comparing the sender field email address with the logged-in user's email address before transmitting the email. When a mismatch is detected, the system proactively displays a warning message to the user, allowing them to correct the issue before the email is sent, thereby preventing potential rejection by the email distribution service.
Solution Approach 2:
The system implements a feedback mechanism by displaying a warning message to the user when the sender field email address does not match the logged-in user's email address. This feedback loop allows the user to be aware of the potential spoofing issue and take corrective action, thus improving email delivery reliability while maintaining transmission flexibility.
2Reliability
If the email address for logging into the distribution service is used as the display address, then the email delivery reliability is improved, but the email transmission flexibility is reduced
Solution Approach 1:
The system dynamically adjusts the email transmission process based on the comparison result between the sender field email address and the logged-in user's email address. When they match, the system proceeds with transmission using the logged-in address for reliability. When they differ, the system activates a warning mechanism that allows the user to choose whether to proceed, thus dynamically balancing reliability and flexibility based on the specific situation.
3Reliability
If a warning message is displayed before email transmission, then the email delivery reliability is improved, but the operation time is increased
Solution Approach 1:
The system applies partial verification by only displaying the warning message when there is a mismatch between the sender field email address and the logged-in user's email address. When the addresses match, no warning is displayed and the email is transmitted immediately. This selective approach ensures that the warning mechanism is activated only when necessary, minimizing the time loss while maintaining delivery reliability.

AI summary
A communication apparatus includes a display that displays an operation screen for transmitting an email using a distribution service; and one or more controllers that control transmission of an email on a basis of an input content input via the operation screen, wherein in a case where an email address for logging into the distribution service and an email address of a sender of the email are different, before the email is transmitted, the one or more controllers display on the operation screen one or both of a warning of a possibility of non-delivery of the email and an operation option for checking arrival of the email.
