I currently have several disposable e-mail addresses at Sneakemail.com, which all forward into my Spamcop account. The page says that I should set up the mailhosts for each e-mail address I have. I registered the first address with no problems at all. When I registered the second address, it replaced the first one on the list of registered servers. Do I only need to register once per mailhost, or once per e-mail address (as the page says) ?
