Default [courier-users] preventing local delivery first --- broken after courier upgrade

BACKGROUND -----------------------------------

We use Postini for spam filtering. We also use courier's
dot-courier-default mechanism so that we can do account-whatever@domain.com.
Therefore, we need mail to work like this:

CLIENT -> OUR SERVER -> POSTINI -> OUR SERVER

This allows us to cram a bunch of aliases into a single Postini account
(this is okay with Postini as we pay on a per user basis). We had achieved
the desired result (before having to migrate to a new server and new courier
install) by having our .courier files for

account-whatever@ourdomain.com

look like this:

| /usr/sbin/sendmail account@postini.ourdomain.com

Mail was delivered to postini, then filtered and non-spam mail was delivered
back to us; this time being delivered to courier as
account@postini.ourdomain.com. Which, of course, the .courier file just
delivers to the Maildir.



THE PROBLEM ---------------------------------

Mail never gets to Postini. Courier's sendmail now seems to first check if
account@postini.ourdomain.com is a local account (which it is), rather than
look at the MX records and try to deliver to the Postini servers. How can I
tell sendmail to NOT deliver locally first?



Thanks for your help!

-Ryan
