Email Management • Tab 4: Configuration • Native 1920x1080 View

📌 Purpose & Quick Summary

Use the Configuration tab to view your server's incoming (IMAP/POP3) and outgoing (SMTP) connection parameters, SSL/TLS security ports, and run the Live Mail Port Health & Firewall Auditor to check if your cloud VPS provider has blocked outgoing mail ports.

🖥️ Interface Tour & Elements

  1. IMAP (Incoming) Card: Displays server hostname, secure port 993 (SSL/TLS), and standard port 143 (STARTTLS).
  2. SMTP (Outgoing) Card: Displays server hostname, secure port 465 (SSL), and submission port 587 (STARTTLS).
  3. POP3 (Archive) Card: Displays secure port 995 and standard port 110.
  4. Mail Port Health & Firewall Inspector: A dedicated live testing tool with an Audit Ports button that probes outbound connectivity to test if ports 25, 465, or 587 are open or blocked by upstream firewalls.

🛠️ Step-by-Step Instructions: Auditing Mail Ports

  1. Click the Configuration tab (mail-config).
  2. Scroll to the Mail Port Health & Firewall Inspector section.
  3. Click the Audit Ports button.
  4. BoostonCP performs real-time TCP socket probes and returns the live status:
    • Port 25 (Standard SMTP): Indicates if your VPS provider (e.g., Hetzner, DigitalOcean, Linode) allows direct outbound port 25 or blocks it.
    • Port 587 (Submission): Indicates if STARTTLS submission is accessible.
    • Port 465 (SMTPS): Indicates if secure SSL SMTP is open.
  5. If Port 25 is blocked by your VPS host, you can switch to SMTP Relay (Tab 5) to route outgoing email through an external provider without needing port 25 unlocked.
