Andy - Some Namecheap record changes needed for signalint.net gmail

on our new signalint.net domain, we have to modify some records in namecheap.

I was logged out from inactivity, so either you can do this or I can do this later, once you help me login to namecheap... please see below for steps to Fix inbound email for signalint.net:

# signalint.net — DNS records to set (Google Workspace)

## 1. Remove first
Delete these existing records:
- All MX → `eforward*.registrar-servers.com`
- SPF TXT → `v=spf1 include:spf.efwd.registrar-servers.com ~all`

Keep the existing Google verification TXT if present:
`google-site-verification=GIau6TewA0RT0Y6EJJrgTX9WMAbl4jjVrCUbZVGu93A`

---

## 2. MX (required)

| Field | Value |
|-------|-------|
| Type | `MX` |
| Host | `@` |
| Priority | `1` |
| Value | `smtp.google.com` |
| TTL | Automatic / 3600 |

---

## 3. SPF (required)

| Field | Value |
|-------|-------|
| Type | `TXT` |
| Host | `@` |
| Priority | — |
| Value | `v=spf1 include:_spf.google.com ~all` |
| TTL | Automatic / 3600 |

---

## 4. DMARC (recommended starter)

| Field | Value |
|-------|-------|
| Type | `TXT` |
| Host | `_dmarc` |
| Priority | — |
| Value | `v=DMARC1; p=none; rua=mailto:admin@signalint.net` |
| TTL | Automatic / 3600 |

Notes:
- `p=none` = monitor only (don’t reject yet) — best for a new domain.
- Change `admin@signalint.net` to whatever inbox should get DMARC reports.
- Later you can tighten to `p=quarantine` or `p=reject`.

---

## 5. DKIM (required for good deliverability)

Generate this in **Google Admin → Apps → Google Workspace → Gmail → Authenticate email → Generate new record**.

Google will give you something like:

| Field | Value |
|-------|-------|
| Type | `TXT` |
| Host | `google._domainkey` |
| Priority | — |
| Value | *(paste the long `v=DKIM1; k=rsa; p=...` string Google shows)* |
| TTL | Automatic / 3600 |

Then click **Start authentication** in Google Admin after DNS propagates.

## Quick checklist
1. MX `@` → `1 smtp.google.com`
2. TXT `@` → `v=spf1 include:_spf.google.com ~all`
3. TXT `_dmarc` → `v=DMARC1; p=none; rua=mailto:admin@signalint.net`
4. TXT `google._domainkey` → *(from Google Admin DKIM)*
