You ask how you can receive email from freeserve, then go on to say you can receive it.
As you presumably have closed your account, you can only receive, not send.
you can of course use a dial up modem and try pay as you go with them. I do this with another ISP and it keeps my email accounts going for less than 10p per month.
Remember to make your freeserve mail server your default if you try to send, otherwise it will try to go through Talk Talk
Just a suggestion.
