Read the mail domain from .env instead of hardcoding it - #1
Conversation
deploy/setup-tls.sh and deploy/verify.sh had mail.sarimtools.com baked in, so a fresh clone would request a Let's Encrypt certificate for someone else's domain and health-check the wrong host. Both now read MAIL_HOSTNAME from .env and fail with a clear message when it is unset. The Apache vhosts become templates with a @@Domain@@ placeholder that setup-tls substitutes, .env.example ships example.com rather than a real instance, and the Python helpers resolve .env relative to the checkout instead of assuming /root/raymail.
📝 WalkthroughWalkthroughDeployment configuration now uses environment-provided domains, checkout-relative paths, and Apache virtual host templates. TLS setup renders configured domains into HTTP and HTTPS configurations. Verification uses the neighboring environment file and Compose file. ChangesDeployment configuration
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The deployment now uses a configurable mail hostname, but malformed or missing configuration can still affect privileged Apache configuration generation and cause verification to check localhost instead of the intended public hostname. These bounded security and rollout-assurance issues should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

🟡 Changes recommended
There are security/robustness issues in the vhost templating (unescaped sed replacement and permission behavior) and deploy/verify.sh currently contradicts the stated “fail when missing” behavior.
Once you've addressed the issues Copilot identified, you can request another Copilot review.
Pull request overview
This PR makes the deployment scripts and Apache vhost configs domain-agnostic by reading the mail domain/hostname from .env instead of hardcoding mail.sarimtools.com, preventing accidental certificate issuance and incorrect health checks on fresh clones.
Changes:
deploy/setup-tls.shanddeploy/verify.shnow derive the mail hostname from.env(and paths are resolved relative to the checkout).- Apache vhosts are converted into templates using a
@@DOMAIN@@placeholder, substituted during installation. .env.exampleis updated to usemail.example.com, and the DNS helper scripts no longer assume/root/raymail.
File summaries
| File | Description |
|---|---|
| deploy/verify.sh | Reads hostname and compose file location relative to the repo instead of hardcoded values. |
| deploy/setup-tls.sh | Loads the hostname from .env and templates Apache vhosts during TLS setup. |
| deploy/raymail.conf | Converts the vhost to a domain template (@@DOMAIN@@). |
| deploy/raymail-http.conf | Converts the stage-1 HTTP vhost to a domain template (@@DOMAIN@@). |
| deploy/dns-records.py | Requires MAIL_DOMAIN to be set and resolves configuration via load_env(). |
| deploy/_stalwart.py | Makes .env resolution relative to the script location rather than /root/raymail. |
| .env.example | Replaces real-domain defaults with mail.example.com. |
Review details
Suppressed comments (2)
deploy/setup-tls.sh:57
- Rollback path has the same unescaped sed replacement and permission-loss issue as the stage-1 install. Escaping DOMAIN and piping through install avoids generating an invalid vhost and keeps file mode consistent.
sed "s|@@DOMAIN@@|$DOMAIN|g" "$HERE/raymail-http.conf" > /etc/apache2/sites-available/raymail.conf
deploy/setup-tls.sh:54
- This sed substitution writes the Apache vhost directly via shell redirection (losing the previous install -m 644 behavior) and does not escape DOMAIN for sed replacement. If MAIL_HOSTNAME contains characters like '&', '|', or '\', the generated config can be corrupted. Pipe into install to preserve permissions and escape the replacement safely.
sed "s|@@DOMAIN@@|$DOMAIN|g" "$HERE/raymail.conf" > /etc/apache2/sites-available/raymail.conf

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.

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.
