So if necessary, someone might expire an "Archived" mailbox instead, or whatever the mail clients like to use. Simply use `&mailbox=Archived` -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
