### DKIM (add AFTER Mailcow is running)
1. Log into Mailcow admin: https://mail.web.orbishosting.com
2. Go to **Configuration → Domains → web.orbishosting.com → DKIM**
3. Copy the TXT record value shown
4. Add to DNS:
| Name | Type | Value |

| `dkim._domainkey.web.orbishosting.com` | TXT | *(copy from Mailcow admin)* |
### PTR Record (Reverse DNS)
Contact your ISP and request a PTR record:

- Points to: `mail.web.orbishosting.com`
This is critical for email deliverability. Without it, many servers will reject your mail.

## Step 3 — Verify FusionPBX Rules Are Intact
After applying the above, confirm your existing SIP/RTP rules still exist:
- Port `5060` UDP/TCP → FusionPBX host
- Port `5061` UDP/TCP → FusionPBX host
- Ports `10000-20000` UDP → FusionPBX host (RTP)
Do NOT remove or modify these.
---
## Step 4 — (Optional) Block SMTP relay abuse
Add a firewall policy to prevent internal hosts from sending SMTP directly (forces use of Mailcow):
- Outgoing port 25 from LAN → blocked (except from 10.48.200.82)
---
## Verification
After applying:
```bash
# Test from external network or use mxtoolbox.com:
# https://mxtoolbox.com/SuperTool.aspx
# Test SMTP
telnet 97.176.15.26 25
# Test IMAP
telnet 97.176.15.26 143
# Test web
curl -I http://97.176.15.26
curl -Ik https://97.176.15.26
```
