Then it sounds like your imapd was not compiled with 
--enable-fulldirhash.  The argument to rehash should match however your 
imapd was compiled (and using someone else's package may make it hard to 
tell).

Your call, but even when I worked at an ISP we had far more problems 
with customers who used POP than those that didn't.

Also, reducing the Cyrus timeout isn't going to help clear the 
half-connected sockets in the kernel if the customers just disconnect 
without dropping all their TCP connections first.
