I understand. It will not and should not be up to me to decide how
that's done. I'm just providing tools and expertise - your
"Mr. Inside", the lead on the conversion, will make the policy
decisions. If that person decides to try this, I can support it.
One way to do it would be to mine the list archives for not just names
but name-date pairs. With a little scripting work that could be processed
into a sequence of map files, each one valid for a known span of dates. The
only assumption required is that an email address is valid for a person
until explicitly superseded by a different address in the archive.
