+```
+
+### 3.11 Validate Internal Access
+
+**Test:**
+
+- [ ] Login
+- [ ] Upload file
+- [ ] Create folder
+- [ ] Restart containers
+- [ ] Data persists
+
+### 3.12 Install Nginx
+
+```Bash

+sudo apt install nginx -y
+sudo systemctl enable nginx
+sudo systemctl start nginx
+```
+
+**Test:**
+```
+http://<IP> → nginx welcome page

+
+```Bash
+</> Bash
+
+sudo tee /etc/nginx/sites-available/nextcloud > /dev/null << 'EOF'

+
+```Bash
+</> Bash
+
+sudo ln -s /etc/nginx/sites-available/nextcloud /etc/nginx/sites-enabled/
+sudo nginx -t
+sudo systemctl reload nginx
+```
+
+*Important*
+- ⚠ This step is NOT fully usable yet

+
+### 3.14 Install SSL (Certbot)
+
+```Bash
+</> Bash
+
+sudo apt install certbot python3-certbot-nginx -y
+sudo certbot --nginx -d drive.company.com
+```

+
+**Replace config**
+
+```Bash

+
+### 3.16 Create Email Provider Account (Fastmail)
+
+**Objective**
+
+Establish a business-grade email platform using Fastmail so that:
+
+- domain-based email (user@company.com)
+- reliable outbound mail (for Nextcloud notifications later)
+- foundation for SPF/DKIM/DMARC
+
+**Architectural Context**
+
+Email is not hosted on your droplet. Your infrastructure will later integrate with it for:
+
+- Nextcloud notifications
+- User accounts
+- Client communication
+
+**Prerequisites**
+- Domain ownership confirmed
+- Access to DNS registrar
+- Decision: Fastmail selected (per runbook)
+
+**Step 1 - Create Fastmail Account**
+
+Go to: https://www.fastmail.com
+
+1.1 Sign up
+- Click Sign Up
+- Choose a plan (Standard is sufficient for pilot)
+- Enter:
+    ```
+    Name
+    Email (temporary Fastmail domain)
+    Password
+    ```
+
+1.2 Complete account creation
+
+You will land in the Fastmail admin interface.
+
+**Step 2 - Add Your Domain**
+
+2.1 Navigate to Domains
+
+In Fastmail:
+```
+Settings → Domains → Add Domain
+```
+
+2.2 Enter your domain
+```
+company.com
+```
+Click:
+```
+Add Domain
+```
+
+**Step 3 - Verify Domain Ownership**
+
+Fastmail will present a TXT verification record.
+
+3.1 Copy TXT record
+
+Example:
+```
+Type: TXT
+Name: @
+Value: fm-domain-verification=abc123xyz
+```
+
+3.2 Add to DNS (Registrar)
+
+In your DNS provider (e.g., GoDaddy or Cloudflare):
+
+Add:
+```
+Type: TXT
+Host: @
+Value: fm-domain-verification=abc123xyz
+TTL: 300
+```
+
+3.3 Wait for propagation
+```
+~5–15 minutes typical, but may be as much as 24 hours
+```
+
+3.4 Verify in Fastmail
+
+Click:
+```
+Verify Domain
+```
+
+Expected Result
+- Domain verified successfully
+
+**Step 4 - Set Domain as Default**
+
+In Fastmail:
+```
+Settings → Domains → company.com → Set as default
+```
+
+This ensures:
+
+- new users → user@company.com
+
+
+**Step 5 - Create Initial Admin Mailbox**
+
+5.1 Navigate to Users
+```
+Settings → Users → Add User
+```
+
+5.2 Create admin user
+
+Example:
+```
+Username: admin
+Email: admin@company.com
+Password: (strong password)
+```
+
+5.3 Save
+
+Expected Result
+
+- Mailbox created
+- Can send/receive (after DNS setup in 3.8)
+
+
+**Step 6 - Basic Access Test (Pre-DNS)**
+
+Login via:
+```
+https://app.fastmail.com
+```
+
+Expected
+- Inbox accessible
+- Account functional (even before MX setup)
+- Email is NOT functional yet
+
+**Validation Checklist**
+- [✔] Fastmail account created
+- [✔] Domain added to Fastmail
+- [✔] TXT verification record created
+- [✔] Domain verified
+- [✔] Default domain set
+- [✔] Admin mailbox created
+- [✔] Able to login to Fastmail
+
+### 3.17 Configure Email DNS
+
+**Objective**
+
+Make your domain fully capable of sending and receiving email by configuring DNS records required by Fastmail:
+
+- Incoming mail routing (MX)
+- Authorized senders (SPF)
+- Cryptographic signing (DKIM)
+- Policy & reporting (DMARC)
+
+*Changing MX records WILL impact live email.*
+
+If the client currently uses another provider:
+
+- Schedule a cutover window
+- Lower TTL beforehand (if possible)
+- Expect brief delivery delays during propagation
+
+**Prerequisites**
+- Domain added & verified in Fastmail (Task 3.7)
+- Access to DNS registrar
+- Admin mailbox created
+
+**Step 1 - Gather Fastmail DNS Records**
+
+In Fastmail:
+```
+Settings → Domains → company.com → DNS Settings
+```
+
+Fastmail will provide all required records. Use those exact values if they differ from below.
+
+**Step 2 - Configure MX Records (Mail Routing)**
+
+2.1 Remove Existing MX Records
+
+⚠️ Only do this at cutover time.
+
+2.2 Add Fastmail MX Records
+```
+Type: MX
+Host: @
+Priority: 10
+Value: in1-smtp.messagingengine.com
+
+Type: MX
+Host: @
+Priority: 20
+Value: in2-smtp.messagingengine.com
+```
+
+**Step 3 - Configure SPF (Sender Authorization)**
+
+3.1 Add SPF record
+```
+Type: TXT
+Host: @
+Value: v=spf1 include:spf.messagingengine.com ~all
+TTL: 300
+```
+
+Notes
+- Only ONE SPF record per domain
+- Merge with existing SPF if present
+
+**Step 4 - Configure DKIM (Email Signing)**
+
+4.1 Get DKIM from Fastmail
+
+In Fastmail DNS settings, copy the DKIM record.
+
+Example:
+```
+Type: CNAME
+Host: fm1._domainkey
+Value: fm1.company.com.dkim.fmhosted.com
+
+Type: CNAME
+Host: fm2._domainkey
+Value: fm2.company.com.dkim.fmhosted.com
+
+Type: CNAME
+Host: fm3._domainkey
+Value: fm3.company.com.dkim.fmhosted.com
+4.2 Add all DKIM records
+```
+
+These enable:
+- Email authenticity verification
+- Better deliverability
+
+**Step 5 - Configure DMARC (Policy & Reporting)**
+
+5.1 Add DMARC record
+```
+Type: TXT
+Host: _dmarc
+Value: v=DMARC1; p=none; rua=mailto:admin@company.com
+TTL: 300
+```
+
+Explanation
+- p=none   → monitor only (safe for pilot)
+- rua=     → aggregate reports sent to admin mailbox
+
+Future Hardening
+Later you can move to:
+- p=quarantine → soft enforcement
+- p=reject     → full enforcement
+
+**Step 6 - Verify DNS Propagation**
+
+6.1 Check MX
+nslookup -type=MX company.com
+
+Expected:
+
+in1-smtp.messagingengine.com
+in2-smtp.messagingengine.com
+6.2 Check SPF
+nslookup -type=TXT company.com
+6.3 Check DKIM
+nslookup -type=CNAME fm1._domainkey.company.com
+6.4 Check DMARC
+nslookup -type=TXT _dmarc.company.com
+
+**Step 7 - Functional Email Test**
+7.1 Send inbound test
+
+From Gmail/Outlook:
+```
+Send email to: admin@company.com
+```
+Expected:
+- Email received in Fastmail inbox
+
+7.2 Send outbound test
+
+From Fastmail:
+```
+Send email to external address
+```
+Expected:
+- Email delivered
+- Not marked as spam
+
+**Step 8 - Validate Deliverability (Recommended)**
+
+Use:
+
+- mail-tester.com
+- mxtoolbox.com
+
+Expected
+- SPF pass
+- DKIM pass
+- DMARC pass
+- Low spam score
+
+**Step 9 - Propagation Expectations**
+- MX:     5–30 minutes typical
+- SPF:    immediate to 1 hour
+- DKIM:   15–60 minutes
+- DMARC:  15–60 minutes
+
+Worst case:
+Up to 24 hours
+
+**Validation Checklist**
+- [✔] MX records updated
+- [✔] SPF record present
+- [✔] DKIM records configured (all 3)
+- [✔] DMARC record created
+- [✔] DNS resolves correctly
+- [✔] Email received externally
+- [✔] Email sent externally
+- [✔] Deliverability validated
+
