## Mailcow Configuration
|
||||
|
||||
### 1. Create Domain
|
||||
1. Navigate to Mailcow admin panel → Domains
|
||||
2. Add new domain
|
||||
3. Select the previously created sender-dependent transport
|
||||
4. Record the generated DKIM key
|
||||
|
||||
### 2. Add DKIM Key
|
||||
- Configure DKIM for both Mailcow and MXroute
|
||||
- Use different selectors for each (e.g., `default` for Mailcow, `mxroute` for MXroute)

## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
1. **Email not sending through MXroute**
|
||||
- Verify SPF record includes MXroute IPs
|
||||
- Check sender-dependent transport is selected in Mailcow
|
||||
- Confirm relay account credentials are correct
|
||||
|
||||
2. **DKIM verification failing**
|
||||
- Ensure both Mailcow and MXroute DKIM records are published
|
||||
- Verify different selectors are used
|
||||
- Check for DNS propagation (24-48 hours)
|
||||
|
||||
3. **DMARC failures**
|
||||
- Confirm SPF and DKIM are properly aligned
|
||||
- Review DMARC reports sent to rua address
