this is from an answer I got from on this problem:

>Yes, you are correct.
>Do to the openess of the internet (SMTP) protocols, that we to which we all
>adhere, making e-mail communications almost effortless, this has become a
>security concern that is plaguing most of the internet industry. We are

>Hope this helps...

Hoping they finish it in time, before the spammers hit us :(
