While most of Rust’s discussion happens on other platforms, email is eternal and
we occasionally need a way to approach individuals or groups privately. Our
email is hosted through Mailgun (provided by Mozilla). We create and edit the
mailing lists for teams through the rust-lang/team repository. Our email
domain is rust-lang.org, e.g. ferris@rust-lang.org.
Sending a public broadcast
If your teams need to reach everyone in the Rust organisation, they can send an
email to all@. It is recommended that you only use this mailing list when you
know that you need to contact every member, such as for organising a members event
like the All Hands, or for security alerts.
Keeping responses private
When sending a message to all@, do not put all@ in To. This will mean that
any replies to your broadcast will also be sent to everyone. Instead, put your
team’s email address in To field, and place all@ in the Bcc field. Then
any replies will be sent to just your team.
