Okay, that would indeed work AND would be *by far* the safest way to do this.

But there are faster and slicker ways.. if slightly more "dangerous".

CAUTION: BACKUP ALL OF YOUR MAIL BEFORE DOING THIS!!!

The KMail that you are using stores it's mail in standard "mbox" or Berkely
Mailbox style files.  This is a single text file with all of the messages in
it.  To combine or merge two mailboxes, then, all you have to do is merge
or combine the two text files.

So say you have $HOME/Mail/inbox and $HOME/OldMail/oldinbox and you want
the former to have all of the messages of the latter.  You can do this
like so:

cat $HOME/OldMail/oldinbox >> $HOME/Mail/inbox

That will append the contents of oldinbox onto inbox.  KMail will then take
care of ordering the messages by date when you start it up the first time.

Be *very* careful about using that command.  Make sure you use >> and *NOT*

appending to it.
