Probably you have your e-mail program configured to send mail in HTML format instead of plain text. You should change your configuration to use plain text only.
If you’re using one of the Microsoft abominations (Outhouse, Outhouse Excess), the forwarded message might still not come out the way SpamCop wants… those atrocious programs tend to “munge” both the headers and body of anything that passes through them, like it was eaten up, passed through the program’s digestive tract, then excreted out the other end. You’re best off switching to a more standards-compliant mail client, like Mozilla or Pegasus.
Incidentally, you’re also violating some standards in your postings here… your quotes and apostrophes are the nonstandard Microsoftism characters that are not part of the ISO-8859-1 character encoding (which Dreamhost’s server announces the forum pages to be using), but only in the proprietary Windows-1252 set (which puts these characters in a range that’s reserved for control characters in ISO-8859-1 and in Unicode). Are you typing them in that way, or pasting in your text from some other program?
