How do I send an email to a Mailman mailing list?
If you are a member of the list, you can send emails to it at firstname.lastname@example.org (where listname is the name of the mailing list).
NOTE: You must be a member of the mailing list to send emails. Even if you are a mailing list administrator, you may not actually be a member of the list.
