empath->mailboxList() gives you the mailbox list
EmpathMailbox::folderList() gives you the folder list
EmpathFolder::messageList() gives you a list of
EmpathMessageDescription, which hold lots of info about the message
(subject, sender, size, date etc).
empath->getEnvelopeOfMessage() (I think you get the idea)

Not yet done, but will be.

These rely on an Empath object existing. 'empath' is Empath::getEmpath()
in the style of KApp. Is that going to cause problems ?

Do you think I've done this right ? I tried to make all services
available from anywhere in the app. Will this translate well into
providing them via CORBA to external apps ?

That would be interesting. I just played with kexplorer (not to my taste
but a very nice app). It would be interesting if mailboxes were
represented as root items in its (/konqueror's) tree view, and folders
beneath. Could make reading mail quite different !

Yup. I was just going to use the current KSpell stuff.

Ok, I was playing the idiot's advocate. I wasn't really suggesting these
things, just showing how it would have to be done currently, and asking
how CORBA would do it.

Yes, thanks.

Will do.
