I'd just like opinions on following point.
With older versions of sendmail, error messages were not generated
if the Precedence is negative. Several lists use this.
With Sendmail 8, all messages get bounced, now the problem
I faced is at sites also having postrmaster copy option where
bounces also annoy the postmaster and not only the list manager.
Sendmail can be modified to handle errors like this:
If precedence > 0, handle the normal way (bounce + postmastercopy)
If precedence < 0, only bounce it and ignore postmastercopy if defined).
This does only concern the local site when the error is generated
at the MLM's machine software.
