Hi,
Why do they need to know which your email is? Sound suspicious to me.
Windows Mail - Tools - Accounts - double click an account - Server Tab - My incoming server is -------
tells you. Other email programs will have similar settings.
You can mix and have pop3 and imap accounts as well. These are examples if using Google - other
email providers probably have similar for at least Pop3 though some are only web based.
