mail: HACK mailcheck update
Update `mail-check` script to notify the user both of newly arrived
mail, and in case he has to enter his password to sync the mail.

HACK the paths and ways of finding out if passwords can be decrypted are
static and only applicable to my set up. This needs to be completely
revised and newly approached.
