Are you talking about 100,000 user accounts or 100,000 IMAP folders? 
Courier is capable of either however your filesystem might not be (or
might be very slow at doing so).  What filesystem are you on?  What do
you
get when you telnet in and try the commands directly (a java apps output
doesn't tell us much).  Are any errors logged to /var/log/maillog? 
Courier should be able to handle as many accounts and/or folders as you
throw at it but you may be hitting a hardware or OS limitation.
