+ALERTA! 🚨 Mailu has dropped support for STARTTLS by default – see details here: https://mailu.io/2024.06/releases.html#starttls-ports-disabled-by-default
+
+If you are relying on STARTTLS, e.g. SMTP port 587, please copy the example `PORTS` variable from `~/.abra/recipes/mailu/.env.example` BEFORE deploying.
