FreeBSD Postfix hash names/depth

[Pete]

Hi, i have install postfix 2.19 and MaiLScanner 4.29-2 and SA 2.63 on
FreeBSD 4.9 -Note i am using the HOLD method of single POstfix usage.
header_checks = pcre;/usr/local/etc/postfix/header_checks
/^Received/ HOLD

Everything works finer, until i do Use Spamassassin = yes  when i do
that i get the following in the maillog, if i do sa = no it is fixed. I
installed the SA port.

Mar 29 15:13:19 mailbsd01 MailScanner[78201]: Messages found but no
hashed queue directories. Please enable hashed queues for incoming and
deferred with a depth of 1 or 2. See the Postfix documentation for
hash_queue_names and hash_queue_depth

I saw int he archives Julian had posted to add hash_queue_depth and
hash_queue_names tot he main.cf but this doesnt help and postconf -d says
depth = 1
names = incoming, active,deferred,bounce,defer,flush,hold

Any ideas?
