1/ For the user-menu on the left, like I did with ripped stuff for DTC,
16x16 x256 colors (gif, may (and should) include transparency):
- My account
- myemail@mydomain.com
- unverified emails
- add pop3 account
- billing
- help

2/ Icons to improve the look & feel of the GUI, should be small and intuitive,
may include the label of the functionnality. Some buttons are in more than
one screen, and image count be the same.

In the list of items:
- Add from address to whitelist
- Add from domain to whitelist
- Delete message (a single trash would do)

At the top of the interface:
- Go to first 20 messages
- Go and see 20 messages before
- Go and see 20 messages after
- Go to see last 20 messages

In the view message:
- View header
- Add from address to whytelist
- Add from domain to whitelist
