Abstract:
Internet mail defines the RFC5322.From field to indicate the author
of the message's content and the RFC5322.Sender field to indicate who
initially handled the message. The RFC5322.Sender field is optional,
if it has the same information as the RFC5322.From field. That is,
when the RFC5322.Sender field is absent, the RFC5322.From field has
conflated semantics, with both a handling identifier and a content
creator identifier. This was not a problem, until development of
stringent protections on use of the RFC5322.From field. It has
prompted Mediators, such as mailing lists, to modify the RFC5322.From
field, to circumvent mail rejection caused by those protections.
This affects end-to-end behavior of email, between the author and the
final recipients, because mail from the same author is not treated
the same, depending on what path it followed. In effect, the
RFC5322.From field has become dominated by its role as a handling
identifier.
The current specification augments use of the RFC5322.From field, by
enhancing DMARC to also use the RFC5322.Sender field. This preserves
the utility of RFC5322.From field while also preserving the utility
of DMARC.
Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
