The sender proposes leveraging Nostr, an open protocol they are involved with, to enhance or replace the existing system. They propose that Nostr can be adapted for this purpose by introducing a new NIP (Nostr Improvement Proposal) that would enable relays to recognize and handle these distinct events effectively.

The idea is to create a versatile mailing list through Nostr that not only supports email communication but also allows the publication of events from various clients. This system would allow different frontend interfaces with varying moderation levels, which could filter emails according to their policies. Ultimately, it is expected that one of these interfaces would become the preferred choice among users. Furthermore, the proposed system suggests that multiple Nostr relays would work in conjunction, sharing certain pieces of information as defined in NIP 11, which may include email addresses, thus ensuring a seamless experience.

The sender identifies themselves with a pseudonym related to floppy disks and indicates that the message was sent using Proton Mail, a service known for its secure email capabilities, emphasizing the importance of privacy and security in their communications.
