Tell the IT Director you want to remove the email address from your record. However, this means you will receive no mailings from the BJCP on any subject, not just competition invites. A better solution is to use a different email address for BJCP email so you can handle it differently. For example, you might create a gmail address like bjcp.X1234@gmail.com where X1234 is your BJCP ID. Then you can filter mail sent to that email address.
