+# Developer help request — updated 2026-06-23
+
+Supersedes `tmp/20260608_help_request.md` for **email inbox** and **clone workflow**.  
+Original PDF still valid for DNS/MX items not listed here.
+
+## Done / updated by agent
+
+| Item | Status |
+|------|--------|
+| Gmail destination | **`bestcastr@gmail.com`** (replaces foxxspambox0@gmail.com) |
+| alpine-be msmtp | `bestcastr@gmail.com` + app password in `/etc/androidcast/msmtp.secret` |
+| Lab cluster mail | cast01: `deploy-mailrelay.sh` (msmtp), PHP `sendmail` transport |
+| Dev clone path | `~/repos/ac` ← `git clone git://f0xx.org/ac/ac-workspace .` |
+| `ac-be-public-assets` | `ac-bash.env` for shared non-secret env |
+
+## Your verification (after agent test send)
+
+1. Check **`bestcastr@gmail.com`** inbox for:
+   - msmtp CLI smoke from cast01 (`Lab mail relay` or similar subject from verify script)
+   - Optional: registration mail after you test `/issues/register`
+2. Reply: **“mail received”** or paste failure (Gmail spam, delay, etc.)
+
+## Still on you (unchanged from 20260608)
+
+| Task | Notes |
+|------|--------|
+| **2.1 DNS** | MX/SPF/DKIM/DMARC — apex `f0xx.org` if `apps.f0xx.org` is CNAME |
+| **ImprovMX** | Activate aliases `info@` / `admin@` / `root@` → **bestcastr@gmail.com** (hoster.by partial) |
+| **FE acl0** | Install `ac-fe.conf` on monstro — see `ac-platform-edge/fe/INSTALL.md` |
+| **Inbound** | Confirm forwarded mail to bestcastr@gmail.com after ImprovMX live |
