I have this in my mail.yml:
# Documentation: https://roots.io/trellis/docs/mail/
mail_smtp_server: smtp.mailgun.org:587
mail_admin: postmaster@app.domain.com
mail_hostname: smtp.mailgun.org
mail_user: postmaster@app.domain.com
mail_password: "{{ vault_mail_password }}" # Define this variable in group_vars/all/vault.yml
How can it be setup for multiple sites? My problem is with mail_user and mail_admin variables, since they require a domain part in them, and I have just a single Trellis folder, so a single mail.yml file.
Is it even possible with multiple sites on a single machine?
