I think you need to better appreciate and understand how fundamental
the "Message" From field for any forms of communications and/or mail
networks is. It would be a radical change to open up this door and
"Pandora box" to make it the norm and mindset that a From: is
unreliable. Not saying it is not prone to abusive, but fundamentally,
when people believe in the message, they also make that natural
trusted tie to the author of the message.
Yes, but nobody is trying to change that. We seem to be agreed that what
a mailing list sends is, from some POV, a "new" message, and so
logically a new "From:" is not wholly out of order.
What's the benefit to this, though, other than obscuring the original
author?
If you agree with John Levine's proposal that mailing list mail is, in
general, not a problem then there is negative value in mailing lists throwing
away (discarding) good mail from domains that happen to use ADSP Discardable
(or any other mechanism for inferring something from the lack of a signature -
this isn't really ADSP specific, it's just the implementation we have at the
moment). If this negative event can be avoided by the simple mechanism of
using a mailing list specific "Message" From, then that is a benefit. This is
not the only potential use of such a feature. I've spoken to one MLM
developer who told me the feature has been previously requested for privacy
reasons nothing to do with DKIM or ADSP.
I think this is quite reasonable as it would inoculate MLM users from ADSP (or
similar) problems in a way that does not limit their ability to promote
communication among their subscribers (which is what mailing lists do).
