In article <609e1c9b-cc4d-d7d1-0fa8-79f515c1eee4@tana.it> you write:

As always, I would want to see some evidence of an actual problem to
be solved here. In the existing format, reporters can and do redact as
much as they want.  Why isn't that sufficient?

Looking at the actual forensic reports I get, the majority are from
antispamcloud.com which gloms some report info and the failed
message's headers into a text body, ignoring the spec that says it's
supposed to be multipart/report. I presume if we changed the spec they
still wouldn't follow it, so why bother.

The rest of the reports are multipart/report, some with the whole
message, some with just the headers.

I think that if a reporter isn't willing to provide the headers it's
unlikely to provide anything.  If we have a concrete reason to believe
that there are people who would send these proposed super-redacted
failure reports who do not send reports now, I might consider this.
Otherwise, it's not a problem and close the ticket.

R's,
John
