Technical Summary

   This document allows broader use of the Expires message header field
   for mail messages.  Message creators can then indicate when a message
   expires, while recipients would use this information to handle an
   expired message differently.

Working Group Summary

   This document had rough consensus in the working group, and
   though all issues were discussed, that did not satisfy all
   dessenters.

   Previous to being put into MAILMAINT, this document was
   discussed in DISPATCH as draft-billon-expires.

Document Quality

   Section 10 lists the references to implementations.

   "Expires" has existed for a long time, going back to the X.400, 
   but it's never been very clearly defined.  Section 2 attempts
   to capture this history and Section 6 acknowledges the possible 
   ambiguity.


Personnel

   The Document Shepherd for this document is Murray Kucherawy. The
   Responsible Area Director is Andy Newton.

IANA Note

  IANA noted one action to be taken, confirmed by shepherd and author
  on 22 April 2026.
