These include emails from about 15 IETF lists,
about 25 other standardization lists, some 20 lists on technical topics,
multiple internal corporate lists, (and even a few emails sent only to
The only way I can deal with this load and maintain my sanity
is by using a large set of sorting rules.
I have quite a few rules dealing with IETF emails that all worked well
until the transition.
I've found over the last ~5 years that the most consistent header on which
to sort is the X-BeenThere: header, which always reflect the list address,
without any other arbitrary junk around it (which unfortunately isn't true
for the the List-ID: header, which has text which may arbitrarily be modified
by a well-intentioned human, making it in practical experience a bit
unpredictable for sorting purposes).
So far, all of my IETF-related MUA sorting rules, which use X-BeenThere:,
have continued to function perfectly across the transition.
