Hi,
Great app. The built in email client is not able to connect to may company's IMAP server, our Seven push mail service has a very limited android client that is unable to download attachment. Your client is working perfect - thank you :-)
Some comments:
1. I would like to have an add free version as well(paypal would be great as I'm from a country not supported by the market yet).
2. The check-boxes are too big before the messages, so even after decreasing the font size (I'm using 14ppt) I can't get more lines on the screen. It would be great to have more messages..
3. On the message screen the body is too small if I use landscape orientation because of the buttons (reply, etc) and the relative big head. As I use mostly landscape for emailing (typing is faster) it would be a great improvement to have a larger space for the body...

Keep up the good work, thank you for the app and I hope, that further improvement will make it even more usefull.

T.
