yes, "leave messages on the server" for "X days" is the answer; that's what I did and it works fine. Probably only tick on one , but you could try both and see if it's useful. As for whether you need to have a separate account, I'd say that depends on whether you WANT two accounts (eg. one you keep for work, one for family & friends?) I've always found that too much trouble, but it's up to you.
