If you have more than 50+ mail in your mailbox you must wait 30 seconds before the additional mail is loaded into your mailbox which makes retrieving mail a timely and annoying task.
Even with the addon Postal which allows you to click “open all” to retrieve all of your mail automatically, you must wait for 30 seconds after it auto loots the 50 mails to refresh the mailbox for the next set of 50 then manually right click the mailbox to start the retrieving process again.
Well there is a new addon that was developed by Zerotorescue. What it does is reload your mailbox every 10 seconds and attempts to auto loot the mailbox, using postal, so that you can be alt tabbed or AFK while automatically retreiving every single mail you have even if its more than 50.
You can download the addon here. Just ensure it is enabled in your addons and you’ll notice it automatically going to work when you open the mailbox.
