[lbo-talk] Free service???

[jbujes at covad.net]

So, I decided to use a personal email address for my non-work mail (my
email has changed to jbujes at covad.net), and I get this email asking me to
register for a free service that will automatically re-direct people who
use my old email....to my new email. I get the option of vetoing anyone I
don't want to have my new email.

Here's the site: http://www.returnpath.net/

My question is, what's the catch? Why is this service free? Any thoughts
or actual information would be appreciated.

Thanks,

Joanna
