Title: (EN) Domain-based Isolated Mailboxes
Abstract: front page image
(EN)

Systems and methods are provided for reducing email spam without wasting network bandwidth. The system contains two groups of boxes. Domboxes and Mailboxes. (a) Domboxes should be used only for non-conversational mails. E.g. website/app mails. Each Dombox has a disposable email address and associated with a primary domain. The primary domain can authorize additional domains in the DNS. We primarily rely on the SPF record for validating Dombox mails. (b) Mailboxes are designed to accept only conversational mails. Conversational Mails can be termed as Human-to-Human, Mailbox-to-Mailbox or MX-to-MX mails. We pull the MX record from the Envelope Domain and verify whether it's really originating from one of the MX servers. Spammer is a Human. Since we accept only MX record verified mails, spammers need registered domains to send spam. Additional checks can be performed with the help of Domain registration date, Spam Filters, Challenge/Response etc.
