I am not familiar with spamassasin but if you are certain that this started happening after the update, is there any possibility of rolling back the update or even doing a reinstallition?
Exchange server 2003 has a junk mail filter which is linked to Outlook 2003, so the settings reside on both applications. If the server is different, then the settings are in Outlook. However since the catergorization is done by Spam Assasin, You need to see why spam assasin does this.

Please refer the link for further info.

I have gone through the "Tips for Legitimate Senders to Avoid False Positives", but can't find anything refering to this these rules. The  problem occured after the newest rule update from SpamAssasin on june 6.

It's not only a problem for the internal email but also got feedback from our customers that mail from us are marked as spam, I guess Spam Assasin is quite common used :)

I guess Spam Assasin will not change their rules, so how can I make Outlook avoid dollars in message ID and insert a "Outlook name" ?

The problem is not only internal but also for all that receive mail from us and use Spam Assasin.
Solved the problem by install this locally -  and use filter for removing message-ID.
