The first and second statistics can be taken care of with management. The last
one is of concern but could also be taken care of with management. Not sure
that it is strong evidence.
I have multiple e-mail addresses, some of them redirections to other addresses
and others that map finally through redirections to multiple addresses and
individuals.
Take mailing list addresses for instance where a single address resolves out to
multiple individuals, some in fact may not be to individuals but expanded out
in other directions, add in wap and it starts getting complicated. It may be
desirable to have an authoritive address for each individual and I assume this
is where this thread is heading. I'm interested in the subject of e-mail which
is why I broke my lurking :).
