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 :).
