Here is a chunk of perl code which uses IMAP to get the mailbox 
location/backend:

##########################
# Locate which backend a mailbox is on
##########################
sub locatemailbox {
         my ($server, $authuser, $authpw, $mailbox) = @_;
         my $location = "";

         use Mail::IMAPClient;

         my $imap = Mail::IMAPClient->new(
                         Server => $server,
                         User => $authuser,
                         Password => $authpw,
                         Ssl => 1,
                         );
         if (! $imap) {
                 die("Cannot connect to mail server '$server' to locate mailbox - $!");
         }

         my @results = $imap->tag_and_run(qq/GETANNOTATION $mailbox "*" "value.shared"/);

         $imap->logout;

         foreach my $r (@results) {
                 $r =~ s/\r//g;
                 $r =~ s/\n//g;
                 if ($r =~ /\/vendor\/cmu\/cyrus-imapd\/server" \("value.shared""(.*)"\)$/) {
                         $location = $1;
                 }
         }

         if ($location eq '') {
                 die("Cannot locate mailbox '$mailbox'.\n");
         }

         return $location;
}



$mailbox is something like "user.morgan".  Basically, you need to look at 
the mailbox annotations to get this.  There are other interesting things 
in the annotations.  Here are the annotations on my own mailbox:

condstore: false
duplicatedeliver: false
lastpop:
lastupdate: 22-Sep-2010 10:01:36 -0700
partition: p4
pop3newuidl: true
server: cyrus-be3.onid.oregonstate.edu
sharedseen: false
size: 67386044
