Deleting email from the hard drive

[Guest]

I use yahoo for email, is there any way that these emails are stored on the
hard drive if I never saved them to begin with? If so, how do I remove them?
Are there any blockers that can be downloaded to stop emails from going to
the hard drive?

No they aren't.
