Erroneous spam filter

[Joe Ward]

After upgrading to Office 2003, all of my email is now
being caught by multiple spam filters with the following
message:

X-RBL-Warning: SPAMHEADERS: This E-mail has headers
consistent with spam [4000020e].

The problem first appeared when sending to other email
addresses within my company and having OUR spam filter
catch all of my mail!

I've changed the mail format to plain text, outlook
native...everything I could think of....any help?

The problem here is a bug in some versions of Outlook 2003 that cause
it to "forget" to add the Message-ID: header to E-mail that is sent
out. The RFCs essentially require that header to be present.
