How do I stop spamassassin from checking email twice

Hi,

I have two mail servers one with domain aaa.com, second bbb.com. Both have
spamassassin installed. Most distribution lists on aaa.com routes emails to
bbb.com. So email gets checked twice.

Adding "whitelist_to aaa.com" in bbb spamassassin configuration is not a
solution because it overwrites result by first spamassassin check.

How can I skip spam checking on bbb.com if email originated from aaa.com ?

Software:
debian 5.0
spamass-milter 0.3.1-2
spamassassin 3.2.3-0.volatile1
sendmail 8.13.8-3 (on bbb.com, can be replaced by postfix if
solution requires it)
postfix 2.5.5-1.1 (on aaa.com)

The general method is to listen on a separate port on bbb.com, and only
allow mail from aaa.com to send to that port. Then, simply configure
your MDA to deliver without a milter for traffic that originated on that
port.

Implementation is left as an exercise for the reader.

Thanks for a fast feedback. I was considering this method myself. But had a
hope there is a more elegant solution.
