[imp] disable restore of draft emails

[Arnold | Universität Bremen]

Hello!
Is it possible to disable the auto recovering of lost draft emails?
Sometimes users writes a email and the browser or the internet 
connection switchs off.
Some days later they login and the draft email will be recoverd.
After that the email will be recovered on every new login.
This users own the same recovered email twenty times or more.

Regards
Arnold
