Internal Draft / Preliminary Configuration Format: .txt (Plain Text) Subject: Unified Access Control for Mail Delivery and Retrieval 1. Introduction
Support for secure handshake protocols, ensuring that only authenticated clients can query the mail store. US MAILACCESS.txt
The US-MAILACCESS.txt document serves as a foundational specification for controlling access to mail server resources within the US-domain network architecture. It bridges the requirements of legacy systems (like IMAP2bis) with modern encryption standards to ensure secure message handling across distributed nodes.
This draft assumes familiarity with ARPA standard mail formats (RFC 5321/5322). It is intended to be used in conjunction with localized firewall rules to restrict access to proprietary mail servers, especially for systems that require specific restricted IP source addresses or browser-based logins. IP ranges and domains permitted for direct relay
Support for enhanced search and mailbox management as detailed in draft-ietf-extra-imap4rev2-30 .
Following the principles outlined in NIST SP 800-177 Revision 1 , this specification prioritizes: The US-MAILACCESS
Implementation of specialized commands (e.g., DMTP) allowing receivers to categorize and decline messages from unverified senders, similar to draft-duan-smtp-receiver-driven-02 . 4. Configuration Directives
