The answer will be found in the civicrm_uf_match table in your Civicrm database. Each Drupal user is connected to its corresponding Civi contact record there.

• The uf_id column is the Drupal user ID.
• The uf_name column is the email address associated with the Drupal user and Civi contact record.
• The contact_id column is the Civi contact record ID.

I don't know the ramifications of deleting the row which contains Drupal user 1, but you could certainly create a new Civi contact record (not yourself), and put that new contact ID in the row with uf_id 1 (replacing whatever value is in the contact_id column currently). Once that is done, you could delete your test contact record safely.

Our Drupal user 1 is associated with a contact record named [myorg] Tech and the email address is tech@[myorg].org. Thus our default address for mailings come from that address with no problems.

Hope that helps!
