How the mailing list service works

The mailing-list service is managed by a mailing-list software: Sympa. This software comes with a web mailing list environment.

To perform actions related to mailing lists (subscribe, change your options, etc.), you have two options:

  • log on to the web environment;
  • send commands by email to the Sympa mailing list manager at

To send a command to Sympa, do as follows:

  • If you send a single command, type it into the subject line of your email and leave its body blank.
  • If you send several commands, leave the subject line of your email blank and type all the commands in the email body. Be careful: Sympa will not process your message unless you respect the following rules:
    • Write every command on a new line.
    • Send your message in plain text, not in HTML (no formatting).
    • Your message can not contain anything else than Sympa commands (no signature block).

A description of all the commands you can send to Sympa is available at mail_commands.
