Abstract:
A number of protocols exist for establishing encrypted channels
between SMTP Mail Transfer Agents, including STARTTLS, DANE TLSA, and
MTA-STS. These protocols can fail due to misconfiguration or active
attack, leading to undelivered messages or delivery over unencrypted
or unauthenticated channels. This document describes a reporting
mechanism and format by which sending systems can share statistics
and specific information about potential failures with recipient
domains. Recipient domains can then use this information to both
detect potential attacks and diagnose unintentional
misconfigurations.
This version updates Security Considerations for +gzip Media Type
suffix, based on feedback from the Media Suffix Designated Expert.
