Postfix error

I just setup my first OS X Server. I performed a clean install of 10.3 Server, setup a couple of users, and turned on mail serving. I am receiving the following error in the log... Feb 26 20:38:13 blueberry postfix/local[3736]: fatal: main.cf configuration error: mailbox_size_limit is smaller than message_size_limit Feb 26 20:38:14 blueberry postfix/master[3343]: warning: process /usr/libexec/postfix/local pid 3736 exit status 1 Feb 26 20:38:14 blueberry postfix/master[3343]: warning: /usr/libexec/postfix/local: bad command startup -- throttling This repeats every minute. Help!
