I'd recommend, though, to implement the possibility to set a different "reply-to" account.
As a matter of fact, I'm compelled (and I suppose, many others are) to use different accounts for outgoing and incoming emails. Other emailing clients for my Nokia allow me to set a different "reply-to" account, this doesn't seem to - unless I am missing something?
In any case, congartulations for the good work.
