What if we change the format of this field into:
X-Mailing-List: <list-submit-address> some_comment
The comment can then contain the name of the list and a sequence number,
or an archive retrieval key, or whatever you like. Or it can even be
By placing the <list-submit-address> up front we ease the parsing of
this field for "dumb" parsers that only want to extract the submit
The X-Mailing-List field should of course not be added by exploders, only
by the originating big list.

Why would you need to know about the names of all the exploders through
which this mail went? For 99.9% of all mails that cause problems it
suffices to know what the name of the last exploder and what the name
of the originating mailinglist was.
The originating mailinglist can be extracted from the X-Mailing-List: field
and the last exploder can be obtained from the Resent-Sender: field which
you override. If you worry about the Resent-From: field, well, you should
only add one if there wasn't already one there.

Sure, add it if you have to. All the mailinglists I run use the
well known daily-quote-request address for administrivia. So, because
this name can be inferred from the mailinglist name, there is no need
to add YAEF (Yet Another Extra Field :-).

I'm missing the submit-address here, it doesn't hurt to include it.
Makes any automated processing so much easier.

Again, add it if you have to. But I'd say that this usually can be
inferred from either the mailinglist name (daily-quote-request would
do in my case, every time), or from the X-Listserver: address.

Definitely a must.
In general I always try to keep the number of extra fields down to a minimum,
while of course ensuring no loss of diagnostics or functionality.
