Hi. I will try to explain what I need. I am using Mozilla as a mail reader. I have set-up two accounts, each account will collect the mail to the same provider with the same login. So, for example, I have set-up : - Account A, pop account X, username Y - Account B, pop account X, username Y (the same one then) But Mozilla does not let me create two accounts with the same pop account and username. So I cannot put localhost in both accounts. So can I put something else that will do the same as localhost ? Thanks If you wonder why I have done such a thing, it is because I want to be able to click on "check mail" button from both accounts (those accounts are in fact identities I use on web surfing), and Mozilla, when we ckick on this button, only checks current account.
