DaemonMailAssist is a mailbox tool that helps with common activities such as grabbing all items and money from your Inbox and providing a To list when sending mail.
For your Inbox, DaemonMailAssist allows you to grab items and money from an open mailbox with a single click. You can choose to grab items, money, or both. You can choose to grab from all senders or a specific sender. This is a great tool for AH toons where you are constantly getting items out of your mailbox.
For sending message, DaemonMailAssist provides you with contact lists to quickly and easily select a message recipient with a single click. You are provided three lists: guild members, friends, and a recently sent to list. Simply click on a name in any of the three lists and the "To:" field of the message is automatically filled in.
