It doesn't -- if you have mail sitting in another mail account that you
want in Cyrus, you will have to use some tool to fetch it from the POP
account and get it into Cyrus, via IMAP/LMTP/SMTP -- there are various
tools out there to do this. However, I would expect most academic
institutions would run their own SMTP server and advertise MX records
for it rather than having their ISP provide the mail server (if the ISP
is providing the mail server, you should probably just use that mail
server rather than setting up Cyrus or any other mail store).

Aside from vacation and reject messages from sieve, Cyrus doesn't send
mail. Your mail clients will send it to a mail server via SMTP.

Not sure what you mean by client, but each message is stored in a single
file in the filesystem with a directory per IMAP folder. Each folder
can have access control to allow one or more users access to the folder.

Yes on OE (we have hundreds of OE users here), I presume Outlook can as
well although I understand it is not a terribly good IMAP client.

If you configure the mail client for your account, sure. However, for
this scenario I would recommend using a web mail client such as
Squirrelmail or Horde IMP.

Read the license for details, but basically you can redistribute it
freely as long as you leave the copyright notice (in binary forms that
means you put it in the documentation).

I assume there are places that will support Cyrus for a fee, but in
general it is volunteer support on a best-effort basis like other open
source code. You have the source, so you can always maintain it
yourself if necessary (and you have the appropriate personnel).
