Under Mail Options there is an option to set Filters.
Create a new one and set it to divert all mail from administrator@yahoo.com (or with subject of Important Notification, whichever) straight to the Trash folder. End of prob.
The problem I have is that the person I am getting all of these emails from is someone I usually get them from--and need to continue getting email from. I talked to others and they are not receiving the same amount of emails. Is there a glitch in my email box?
