Mail-gate

Mail-gate: Open-Source Email Gateway Software

Mail-gate improves email deliverability and security by validating and filtering incoming emails to block spam and viruses, routing legitimate messages to your email server.

What is Mail-gate?

Mail-gate is an open-source email gateway application designed to enhance the security and deliverability of business email. It acts as an intermediary between the public internet and a company's email server to protect against spam, malware, phishing attacks, and email-based threats.

When implemented in front of an existing mail server, Mail-gate validates incoming SMTP connections before accepting messages. Using Rspamd filtering and other techniques, it analyzes email content in real-time to catch threats like viruses, spam, and phishing attempts. Legitimate messages are delivered to the internal mail server while unwanted mail is blocked or quarantined.

Key features of Mail-gate include:

• Modular, scalable architecture built with Node.js
• Validation of incoming SMTP sessions before message acceptance
• Multi-layered content filtering via Rspamd to detect spam & threats
• Customizable greylisting to temporarily defer suspicious messages
• Scoring and rules engine to fine-tune filtering policies
• Quarantining of messages that seem malicious or questionable
• Integration with antivirus software for deeper content scanning
• Logging and metrics for monitoring and troubleshooting
• Designed to improve email deliverability by maintaining sender reputation

With its security capabilities and deliverability features, Mail-gate acts as an effective shield to stop undesirable email from flooding mailboxes while allowing legitimate messages through. Its customizable nature provides flexibility to tailor filtering policies to an organization's specific needs.
