Technical Summary
    The Open Pluggable Edge Services (OPES) framework is application
   agnostic.  Application specific adaptations extend that framework.
   Previous work has focused on HTTP and work for SMTP is in progress.
   These protocols differ fundamentally in the way data flows and it
   turns out that existing OPES requirements and IAB considerations for
   OPES need to be reviewed with regards to how well they fit for SMTP
   adaptation.  This document analyzes aspects about the integrity of
   SMTP and mail message adaptation by OPES systems and privacy and
   security issues when the OPES framework is adapted to SMTP and lists
   requirements that must be considered when creating the "SMTP
   adaptation with OPES" document.
Working Group Summary
 There was consensus to publish this document as a record of the
  working group's discussion.  There were comments on the IETF
