Another problem is that Gmail will base64-encode any message that has a non-ASCII character. That includes things like European names. + +Proton Mail +*********** + +Proton Mail has a "feature" where it looks up keys using Web Key Directory +(WKD) and encrypts mail to any recipients for which it finds a key. +Kernel.org publishes the WKD for all developers who have kernel.org accounts. +As a result, emails sent using Proton Mail to kernel.org addresses will be +encrypted. +Unfortunately, Proton Mail does not provide a mechanism to disable the +automatic encryption, viewing it as a privacy feature. +The automatic encryption feature is also enabled for mail sent via the Proton +Mail Bridge, so this affects all outgoing messages, including patches sent with +``git send-email``. +Encrypted mail adds unnecessary friction, as other developers may not have mail +clients, or tooling, configured for use with encrypted mail and some mail +clients may encrypt responses to encrypted mail for all recipients, including +the mailing lists. +Unless a way to disable this "feature" is introduced, Proton Mail is unsuited +to kernel development. |
