Mail Server Segmentation for Attachment Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a user replies to an email with a new attachment, the original attachment is often not received by the newly added recipient, and existing recipients are inconvenienced by receiving the original attachment unnecessarily.
Innovation Solution
A mail processing method where a server generates two data packets based on a predetermined rule for non-regular mails, one carrying the original attachment and the other not, with the mail header of the packet carrying the original attachment set to the new contact and the header of the packet without the original attachment set to existing contacts, ensuring the original attachment is only sent to the new contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct reply is used, then the reply process is simple and fast, but the newly added recipient cannot receive the original attachment
Solution Approach 1:
The patent segments the mail reply process into two separate data packets: one containing the original attachment and one without. This segmentation allows different recipients to receive different versions of the reply, solving the problem of incomplete attachment delivery while maintaining operational simplicity through automated server-side processing.
Solution Approach 2:
The patent applies local quality by providing different content (with or without original attachment) to different recipients based on their specific needs. New contacts receive the complete package with original attachment, while existing contacts receive only the reply body, optimizing the delivery experience for each group.
2Reliability
If reply with original attachment is sent, then all recipients can receive the original attachment, but existing recipients are inconvenienced by receiving unnecessary attachments
Solution Approach 1:
The patent implements local quality by customizing the reply content for different recipient groups. Existing recipients receive replies without the original attachment since they already have it, while new contacts receive replies with the original attachment. This targeted approach improves recipient convenience while maintaining attachment delivery completeness for those who need it.
Solution Approach 2:
The patent segments the reply into multiple data packets distributed to different recipients based on their contact status. This segmentation eliminates the need for existing recipients to handle unnecessary attachments while ensuring new contacts receive complete information, thereby improving overall recipient convenience.
3Adaptability or versatility
If reply with new attachment is sent, then new information is provided to all recipients, but the original attachment is lost in the communication chain
Solution Approach 1:
The patent segments the reply data into separate packets, with one packet specifically containing the original attachment. This ensures that when new attachments are added to the reply, the original attachment is preserved and delivered to appropriate recipients, preventing information loss while maintaining adaptability for information updates.

AI summary
Mail processing methods and a server are described. The server receives a mail reply request sent from a client, determines whether a new contact and an original attachment are present in the mail reply request, and if it determines that the new contact and the original attachment are present in the mail reply request, generates a data packet based on a predetermined rule for non-regular mails, and transmits the data packet to a destination.
