Why does the mail server say my password is wrong. It's not!

Most commonly, users are continually prompted for their password by the mail server if they have entered their mail login name incorrectly. If it is not in all lower case, it will prompt you for the password again because it does not recognize the username. There may also be space before or after the login name; while you may not see it, the computer will. You can try deleting it and re-entering the username in lower case to fix the problem.

Also, the mail program encounters a problem on the mail server (such as a POP lock or connection problem), they might re-prompt the user to enter their password. This is not an indication that the user is entering a password incorrectly, or that the password is incorrect on the server, but that there was a previous error. If this happens to you, re-enter the password and check to see if there's another error message that appears that indicates that there is a POP lock or from lines error.
