How does Mail Gateway EG-Platform prevent spam email?

Spam Guard Core Features

Block Spam EG-Platform provides features to optimally filter email spam based on Machine Learning technology (machine learning) to learn about spam, and promotional mail and evaluate incoming mail based on the spam email scale. In particular, Spam Guard is capable of preventing even bulk mail spam attacks.

Email spam score scale

• Check RBL (Real-Time Blackhole List): RBL is a blacklist containing the IP addresses of email servers that are considered the source of spam emails or other spam activities. RBL is used to check if a particular IP address is blacklisted or not.

• Check SURBL (Spam URI Realtime Blocklists): SURBL is a type of blacklist used to check links contained in emails, where these links are identified as links to websites containing spam content, phishing, or malware.

• Regular Phrase Checker: Checks for regular expressions used in spam emails such as “free”, “discount”, “earn money”,…

• Email Server Protection: EG-Platform also allows access control to the mail server, ensuring that only authorized people can access it.

• Email Authentication the process of determining the authenticity of an email sent from a particular source. This process is done by examining the information attached to the email to determine whether the email is from the specified person or organization.

• SPF Sender Policy Framework determines whether an IP address is authorized to send email to the specified domain.

• DKIM (DomainKeys Identified Mail): uses a digital signature to verify the authenticity of the email and determine if the email was sent from the specified domain.

• DMARC (Domain-based Message Authentication, Reporting, and Conformance): combines both SPF and DKIM to authenticate emails and establish rules for handling unauthenticated emails.

- Set up a gray list: a technique to block spam on email by delaying the delivery of mail to its destination. When a new email is sent, the server will not accept it immediately, but temporarily reject it and ask to resend it after a certain period of time. Greylist allows legitimate emails to be resent after a period of time and accepted by the server, while spam emails are usually not sent back.

- The system also prevents illegal use of forwarding servers: Spam guard also prevents an email server from being used to forward emails without the owner’s or admin’s permission or access server member.

Spam Guard filter proactively prevents email spam based on AI self-learning with Bayesian spam filter. This technique uses a machine learning algorithm to learn from spam and valid mail patterns, based on words, phrases, email addresses, message lengths, and more. During the learning process, the Bayesian filter calculates the probability to consider a new message as spam or a valid message. This helps the business email system filter spam more effectively.

Overview of Spam Guard’s steps to block spam mail

Incoming mail will be evaluated by Spam Guard through the use of Bayesian filter technology, and using machine learning to evaluate on a spam scale. Also, check the authenticity of incoming emails through SPF, DKIM, and DMARC standards. Then block emails containing viruses and invalid forwarding messages. Through the above process, mail to users will be guaranteed to be clean mail and improve operational efficiency.
