6.4 Mailing Lists

Zoom Mail Service supports mailing lists but, at the moment, membership is entirely managed by the server, and we do not support end-to-end encrypted emails to these lists. When a client sends an email to a mailing list, the server obtains the plaintext and reencrypts it for each member of the mailing list individually (as for emails from external senders). The re-encryption is the same as for emails that came from an external sender. We will continue to improve this design in the future.
