saved mail correspondance

There are often some mails that I want to save for a period of time (buff lists etc.), and put apart that I dislike a cluttered inbox, I would like a "saved mails" box in the mail system.

The mails I want to save sometime gets deleted because I get 50 "you have been buffed by" mails plus some battle reports. When I get a little impatient, I overlook the mail I want to keep, and it gets deleted.... I'm tired of that.

A "workaround" that would work too is a button for "delete buff messages" and one for "delete battle reports" ... most of the time these are the mails I want to delete anyway.
