This could be replaced with DKIM sigs, I guess. > X-Mailman-Rule-Hits > X-Mailman-Rule-Misses This might be useful for diagnostics, but probably wants to be off in general. My view is that Mailman should not be doing message filtering. > X-BeenThere I guess that's useful for avoiding list loops, perhaps? > X-Mailman-Version I think this should be replaced with X-Mailer, or even User-Agent. That's not currently an SMTP header, but I think it should be.

Thunderbird does, as do some other mail clients. Or, we should push for introduction of a List-Agent header. > X-List-Received-Date Don't the Received headers carry this information? > X-Approve > X-Approved > > -Barry Generally, I think we should avoid the use of headers that duplicate other existing headers. Where we want to add more information, then extend the List-* header set if the information might be generally useful for mailing list software. Otherwise, use X-Mailman-* (or even Mailman-*) so that people know where the header came from. -- Ian Eiloart Postmaster, University of Sussex +44 (0) 1273 87-3148 _______________________________________________ Mailman-Developers mailing list Mailman-Developers@python.org http://mail.python.org/mailman/listinfo/mailman-developers Mailman FAQ: http://wiki.list.org/x/AgA3 Searchable Archives: http://www.mail-archive.com/mailman-developers%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-developers/archive%40jab.org Security Policy: http://wiki.list.org/x/QIA9
