Keep the missing-variable diagnostic reachable.

When MAIL_HOSTNAME is absent, set -euo pipefail makes the assignment fail at the grep pipeline, so the explicit validation message is not reached. Make the lookup tolerate the no-match status.

minimal, and validate.

In `@deploy/setup-tls.sh` at line 14, Update the MAIL_HOSTNAME lookup used to
initialize DOMAIN so a missing match does not fail under set -euo pipefail;
tolerate the grep no-match status and preserve the subsequent explicit
validation diagnostic for an absent variable.

Fail when MAIL_HOSTNAME is missing.

The localhost fallback hides a missing ../.env value. Later checks can target localhost instead of the deployment hostname and validate the wrong system. Exit with an error when DOMAIN is empty.

Proposed fix 
-DOMAIN="${DOMAIN:-localhost}"
+if [ -z "$DOMAIN" ]; then
+  printf 'Set MAIL_HOSTNAME in "%s/../.env" first.\n' "$HERE" >&2
+  exit 1
+fi

In `@deploy/verify.sh` at line 5, Update the DOMAIN initialization in the

defaulting to localhost, and exit with a clear error when it is missing.
Preserve the existing hostname validation flow when DOMAIN is provided.
