# Create or update a Mailcow mailbox via API.
#
# Usage:
#   make mailcow-mailbox MAILBOX=alerts
#   # or with env (after: source scripts/load-mailcow-vault-env.sh):
#   MAILBOX_LOCAL_PART=notify MAILBOX_NAME="Notify" MAILBOX_PASSWORD='...' ./scripts/mailcow-mailbox.sh
#
# Variables (env or make):
#   MAILBOX / MAILBOX_LOCAL_PART — local part (required)
#   MAILBOX_NAME — display name (default: title-case of local part)
#   MAILBOX_PASSWORD — if unset, loaded from vault_mailcow_mailbox_passwords[local_part]
#   MAILBOX_QUOTA — MiB (default 1024)
#   MAILCOW_URL, MAILCOW_DOMAIN, MAILCOW_API_KEY — see load-mailcow-vault-env.sh
