Thanks Merrill, I was not aware of such problem with people putting
"wrong" addresses. In fact, at CERN we don't have this problem too much
because we recommend people to use Generic Addresses (GEM in our jargon)

Moreover, we keep updated an "address closure" table which contains user
information and in particular all the centrllay managed combinations of
login_id and host machine + a secondary cluster table for cluster

So, my entry in this table looks like:

We are then using this table to "normalise" mailing lists and to improve
the validation mechanism (make it more friendly).

We are maintaining 600 mailing lists (with 1 to 2000 members) per list.
Some mailing lists are automatically generated from our Central Registry

All of this contributed to improve the user friendliness and to limit the
number of errors.
