Installation

The CyberMail module is included in CyberPanel 2.4.5+. No separate installation needed.

Verify the Module

# Check the app exists
ls /usr/local/CyberCP/emailDelivery/

# Check it's in INSTALLED_APPS
grep -n "emailDelivery" /usr/local/CyberCP/CyberCP/settings.py

# Run migrations if needed
cd /usr/local/CyberCP
python manage.py migrate emailDelivery

Database Tables

The module creates two tables:

Table	Purpose
cybermail_accounts	Stores per-admin CyberMail account connections
cybermail_domains	Tracks sending domains and their verification status

Getting Started

Step 1: Access CyberMail

Navigate to: https://your-server:8090/emailDelivery/

You’ll see the CyberMail marketing page with plan information and a “Get Started Free” button.

Step 2: Connect Your Account

1. Click “Get Started Free”
2. Enter your email address (defaults to your CyberPanel admin email)
3. Create a password for your CyberMail account
4. Click Connect

This registers your account on the CyberMail platform and obtains an API key that’s stored locally for future API calls.

Note: If you already have a CyberMail account on the platform, use the same email and password. The system will link your existing account.

Step 3: Add Sending Domains

1. After connecting, you’ll see the dashboard
2. Go to the Domains tab
3. Click “Add Domain”
4. Enter your domain name (e.g., example.com)
5. Click Add

The system will:
– Register the domain on the CyberMail platform
– Automatically create SPF, DKIM, and DMARC DNS records in PowerDNS
– Report how many DNS records were configured

Step 4: Verify Domain

1. Click “Verify” next to your domain
2. The system checks SPF, DKIM, and DMARC records
3. Green checkmarks appear for each verified record
4. Status changes to “Verified” when all records pass

DNS Propagation: If verification fails immediately after adding, wait 5-10 minutes for DNS propagation and try again.

Step 5: Enable SMTP Relay (Optional)

The SMTP relay routes ALL outgoing email from your server through CyberMail:

1. Go to the Relay tab
2. Click “Enable Relay”
3. The system will:
4. Create (or rotate) SMTP credentials on the platform
5. Configure Postfix with the relay host (mail.cyberpersons.com:587)
6. Set up SASL authentication
7. Enable TLS encryption

What gets configured in Postfix (/etc/postfix/main.cf):

relayhost = [mail.cyberpersons.com]:587
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtp_tls_security_level = encrypt

Dashboard Overview

After connecting, the dashboard provides five tabs:

Domains Tab

• Lists all sending domains with verification status
• SPF, DKIM, DMARC status badges (green = verified)
• Actions: Verify, Auto-Configure DNS, Remove
• DNS auto-configuration works when the domain exists in PowerDNS

SMTP Tab

• Manage SMTP credentials for sending
• Create new credentials with descriptions
• Rotate passwords (one-time display)
• Delete unused credentials

Relay Tab

• Shows current relay status (Enabled/Disabled)
• Displays relay host and port
• Enable/Disable toggle
• Relay info: mail.cyberpersons.com:587 with STARTTLS

Logs Tab

• Paginated delivery logs
• Filter by: Status (delivered/bounced/failed), Days (1-30)
• Shows: Date, From, To, Subject, Status
• Color-coded status badges

Stats Tab

• Aggregate stats: Total Sent, Delivered, Bounced, Failed, Delivery Rate
• Per-domain breakdown table
• Useful for identifying domains with deliverability issues

Disconnecting

1. Go to https://your-server:8090/emailDelivery/
2. Click the “Disconnect” button
3. Confirm the action

Troubleshooting

“Account not connected” error

The admin session doesn’t have an active CyberMail connection. Click “Get Started Free” to connect.

DNS records not auto-configured

• The domain must exist in PowerDNS on this server
• Check if the domain was created via CyberPanel’s DNS management
• If using external DNS, add records manually using the DNS records shown on the platform

Domain verification failing

• Wait 5-10 minutes after DNS changes for propagation
• Verify records exist: dig TXT example.com +short
• Check for conflicting SPF records (only one SPF record allowed per domain)

SMTP relay not working

• Check Postfix status: systemctl status postfix
• Verify relay config: grep relayhost /etc/postfix/main.cf
• Check SASL credentials: cat /etc/postfix/sasl_passwd
• Test connectivity: telnet mail.cyberpersons.com 587
• Check mail queue: mailq
• View Postfix logs: tail -f /var/log/mail.log

Relay shows “Failed to configure”

• Ensure /usr/local/CyberCP/plogical/mailUtilities.py has the configureRelayHost method
• Check file permissions on /etc/postfix/sasl_passwd
• Verify Postfix is installed and running

Emails still going to spam

1. Verify all DNS records (SPF, DKIM, DMARC) are green
2. Check your domain’s reputation at https://www.mail-tester.com
3. Ensure you’re not sending to purchased/scraped lists
4. Consider upgrading to a plan with dedicated IPs

Security

• API keys are stored per-admin in the local database, never in config files
• All platform API calls use HTTPS with Bearer token authentication
• SMTP credentials use SASL over TLS (STARTTLS on port 587)
• SASL password file is chmod 600 (root-only readable)
• Session-based authentication with CSRF protection on all endpoints
• Passwords are never stored locally — only on the platform
