[https://github.com/i2p/i2p.i2p-bote I2P-Bote] is a serverless, encrypted email plugin that uses [[I2P|I2P]] for anonymity. Messages are stored in the [https://en.wikipedia.org/wiki/Distributed_hash_table distributed hash table (DHT)] for 100 days, during which the recipient is able to download them.
