Introduction

Email is a primary mode of communication for vessel-to-port coordination, cybersecurity alerts, and crew operations. However, email failures, spam issues, and phishing attacks can cause communication breakdowns.

Common Email & Communication Problems

📧 Delayed or Undelivered Emails – Shipboard networks may have restricted outgoing mail servers, leading to email delivery failures.

📧 Spam & Phishing Emails – Crew members may receive fraudulent emails impersonating shipping authorities, leading to potential cyber threats.

📧 Attachment Size Limitations – Sending large files (reports, security logs, video footage) over email may fail due to server limitations.

How to Optimize Email Communication on Vessels

✔ Use Dedicated Email Servers – Set up dedicated mail servers to handle outgoing/incoming communication efficiently.

✔ Enable Email Filtering & Spam Protection – Use AI-powered spam filters to prevent phishing emails from reaching crew inboxes.

✔ Increase Attachment Size Limits – Optimize onboard email servers to handle larger file attachments without failure.

✔ Implement Secure Email Authentication – Use DKIM, SPF, and DMARC protocols to prevent email spoofing and unauthorized access.
