People are telling me that they are receiving e-mails from me as zip
files or word documents.  When I send these e-mails they do not have
attachments or do I send any zip files.

I person says it comes as a zip file and then when he opens it, it
shows up as a word document.

I am using outlook 2003.  I have turned off html  in outlook as well
as changed it to plain text and back to no avail.

Any ideas.

This means you have a third-party add-in installed that is performing the
zipping automatically.  It's probably this one:
