Hi all,
here is a small application that will help you to "hack" your MfE/Email accounts. Recently I wrote about this application in Email/MfE thread.
All sources can be found on GitHub. It is quite small application that allows you to change your MfE/Email accounts settings (in theory it can be used to change settings in any account) and map you account's standard folders.

It is my first experience (and experiments ) with QML.

.deb package is attached. First of all let me explain how it works. On the first page you should click on an account that you'd like to edit. On the second page you will see the list of ALL account's settings (currently they are shown as Strings). You looking for a setting(s) that you want to change, changing it(them) and then clicking on a "save setting" button in a menu.

Now, about some "hacks":
1) As far as I remember there were a question about "how to sync all emails from my MfE account". Here is the answer:
All you need to do is to set the MfE account's setting "email/past_time" as 0 (and click "save setting" button after that of course :-D ).

2) And about downloading full message's MIME. MfE accounts have 2 settings: "email_mime" and "email/email_mime". If you want to enable it then change both settings to "TRUE".

WARNING and NOTE:
1) The first 'hack' might confuse you a bit, because after that you will see sync back mails option as "3 days" value in the accounts application (plus it might overwrite this setting in the DB, so it's better to not save it at all (or even not open mail account settings)).
2) This application (MeMailSettings) is made by my self and it is not the Nokia app.
3) If you will change something to an invalid value your account(s) can become "wild" and do something nasty, so please be careful and change anything only on your own risk.
!!!!THIS IS NOT SOMETHING RECOMMENDED TO DO. DO IT IF YOU KNOW WHAT YOU ARE DOING. DO IT ON YOUR OWN RISK !!!!!!!
