I have a much more naive question along the same lines.
Apologies if it is too far from the original query.

I'm running an IMAP (dovecot) server,
with my mail stored in ~/maildir .
I'm using KMail on my laptop to access the server (on another machine).

I'd like to archive some of my older email,
ie transfer it to another disk on the server,
but I don't understand exactly what will happen
if I run Folder=>Archive Folder on my laptop,
and don't like to try it without more knowledge.

Will the folder disappear from the list I see in KMail?
Will the archive be saved on my laptop or on the server?
In what format?
Will I be able to "un-archive" it if I wish?
Will the various dovecot index files be updated appropriately?

I suppose my problem basically is that I don't know
how kmail on my laptop and dovecot on my server interact.
