I will consider writing a complete e-mail client with good password encryption, but that requires a lot of work, so most probably it will come one day in later versions. I just don't want to make anything that would create some kind of a security risk.

The security risk i am talking is for example native e-mail client on nokia,
if you let me hold your phone for 15 seconds I am able to check all the passwords for your e-mails and a lot of other stuff. Please don't ask me how, I will not show it, will not write it, will not say it

Briefly:
I will take it under consideration, but in later version of the software.
