## Network Details

**Mail Server:**
- Internal IP: 172.16.4.250 ✅ (accessible)
- External IP: 172.99.62.118 ❌ (firewall blocks external access)
- Hostname: mail.mavrix.one
- Software: Postfix (ESMTP Postcow)

**Ports:**
- SMTP: 587 (TLS/STARTTLS) ✅
- SMTPS: 465 (SSL) - not tested
- IMAP: 993 (SSL) ✅
- IMAPS: 143 (TLS) - not tested

## SSL Certificate Note

The mail server has an SSL certificate for `mail.mavrix.one`, but we're connecting via IP address `172.16.4.250`. 

**Solution:** SSL verification is disabled in code:
- `EmailService.php` - Line 54-60
- `SettingsController.php` (testSmtpConnection) - Line 1062-1069

This allows connection despite certificate CN mismatch.
