I've had my N800 for a few years now, but I've always used webmail on it so never setup the email client. I'd like to do that now for my work email, but I have a few basic questions that I want to confirm first.

1) I'm running Diablo, does this mean that the default email client is Modest? Is Claws the only other real option, or are there others I should look at?

2) I'd like to use this for work email, but my understanding is there is no Diablo client that will export Exchange? We also have IMAP support enabled, so I should be able to use that if needed, but that is a lot more limited in what I can access.

3) For IMAP how does the email fetching work is it push or pull? And will leaving the mail client running pretty much all the time eat up the battery?

I know these devices are not meant to be used as a PIM, but I'm hoping I can use it that way as best as I can for a few months until a better option comes along.
