Me.com email addresses online?
Macrumors.com is reporting that for some .Mac users, using a me.com email address seems to be working. For instance, if your .Mac account name is username, sending an email to username@me.com works the same as sending one to username@mac.com.
Your mileage may vary -- as of 8:35 PM EDT on Saturday, June 28, 2008, it wasn't working for me.
Update: About four hours later, it's working for me.
