How to prevent Spam, Forged and Scam Mails?

Three ways to approach spam, scam and forged emails: blocking, pattern detection and filtering.

  1. Use DNS to list sites authorized to send email and determine the reputation of those sites.

  2. By challenge/response systems or C/R (channel mail), unknown senders are required to pass various tests before their messages are delivered.

  3. By country-based filtering, you can block email from certain countries that you receive a great deal of spam.

  4. DNSBLs or DNS-based Blacklists are used for filtering and blocking.

  5. Enforcing RFC standards for Simple Mail Transfer Protocol (SMTP) are used to judge the mail being a spam.
