How to change number of email messages shown

By default, inbox/read/deleted messages are only 10 per page, how Can I Set this to be 25 by default? Also, how can I removed the greetings checkbox at the top of the pages? I have greetings disabled, and would like to remove the checkbox so that it only shows messages. Also, the menu bar in mail that has compose | sent | inbox | trash, the compose link opens in a new window, I'd like to change it to open in the SAME window, like the other links.

Thanks

1. Change default per page value:

Open the inc/classes/BxDolMailbox.php

find and replace this code line:  $this -> aMailBoxSettings['per_page'] = 10 ; with your value

2. Remove greetings from mailbox

You should remove the greeting value from Type field in sys_messages table

clear all caches
