Sorry, I should also note that this is a big problem for me. I've got several sites with an firstname.lastname@example.org
address, which is used by online ordering forms for the site in question. I can get the sites to change that, and create email@example.com
addresses (which won't collide in local delivery) and get the PHP programmers to use that, but it seems clumsy and hackish, and means one more thing to spell out for programmers doing work for any of my sites.
