outlook 2003 i have repeatedly added a sender from a hotmail account, only to
have it removed from the blocked senders list every time i close my outlook.
also i have received emails from the same sender when the address was in the
blocked senders list. anyone know how to fix this?

Try this Microsoft Knowledge Base article:

"E-mail addresses have been deleted from the Safe Senders tab, from the Safe
Recipients tab, and from the Blocked Senders tab in Outlook 2003"
