Blocking someone from access to an email address

[JGAL19]

How do i block someone from having access to an email address.

Do you mean to block someone from ever finding out an email or to block them from being able to send you an email?

If you mean to keep from getting emails from someone, you can create a "Safe List" that includes only those persons/companies from whom you want to receive emails. If they are not in that list and your settings are correctly marked, you won't be hearing from them via email!
