I'm not sure what anyone else has heard but this "new" 602P bill going through the House of Representatives (I think) bill would state that the USPS would get 5 cents for every email sent by anyone online in the United States.

Wanting to find out more on this, I went and searched on www.google.com for 'postal service email charge' and found this page (http://urbanlegends.about.com/library/blemtax2.htm) that clarified a lot of things.

Check it out. I found it a good read and maybe someone else will too.
