"Email using too much memory
My email usage is at 548mb although I've deleted most of the emails.  When I receive and delete emails, it still adds to the total usage.  I'm using an email account on a pop3server from my PC.  What can I do to dump the memory and prevent this from happening again.  Many thanks."
