Hello @timthuston,
Thanks for reaching out on the forums, we're here to help! To get started can you confirm if this is a residential account or a business account? Additionally, have you already sent an email to abuse_rbl@abuse-att.com, if not you can check out our Postmaster site for more information. We look forward to hearing back from you!
