The IESG has received a request from the Using TLS in Applications WG (uta) to consider the following document: - 'SMTP TLS Reporting' <draft-ietf-uta-smtp-tlsrpt-17.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2018-04-02. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. 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 attackers and diagnose unintentional misconfigurations. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-uta-smtp-tlsrpt/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-uta-smtp-tlsrpt/ballot/ No IPR declarations have been submitted directly on this I-D.
