From what I read on that page, that is essentially what
mailman does (at
least as one of the options), but in a slightly less
confrontational way (i.e. not From: 'bad mail config at
sender', but simply From: 'replaced by list'). It even notes
that it breaks reply-to and search, though it certainly
doesn't make an exhaustive list of UI/client processing
problems.
For better or worse, we've got a perfectly good, standard, way
of doing that when the list is to be treated as the sender.
That would be to ask developers of list software to use
Resent-From. It has its own set of issues and the various bits
of software that try to tie keys and DNS records to mail
originators would need to be upgraded to understand the
semantics of "Resent-*" (and, btw, Sender) fields, but it would
conform to the standards, not loose information, and not closely
resemble a cheap hack.
