What
Templates could not send mail: every message bounced with
postfix/error ... relay=none ... status=bounced ([smtp.gmail.com]:587).Cause
The builder preseeds Postfix as "Local only". Debian's postinst then sets
default_transport = errorandrelay_transport = error, and nothing removed them, so Postfix never contacted the relay.Change
build-templates.sh:postconf -X default_transport relay_transportafter the main settings.verify-template.sh: new check that both are unset (FAIL shows their values).Found by running
verify-clone.sh(#50) on a clone of template 9003;postconf -nthere showed both set toerror.Existing templates need a rebuild (or
postconf -X default_transport relay_transport && systemctl reload postfixon a clone to confirm).Testing
bash -nand shellcheck clean. Not rebuilt or run on a real Proxmox host.
