Thier is another option, you can add a MailSweeper program to ensure that your email program only downloads to emails you want to see.
It will also help in dealing with spam. A free one available is
MailWasher
At Work we get on average 100-400 Viruses a day and and at least that many spam emails too, so our MailSweeper is a lot more advanced than MailWasher, but it seems like a good home application.
