This step is only required if you are setting up a custom DKIM record for your organization.


A feedback loop (FBL) is a communication channel with an Internet Service Provider (ISP) that allows abuse complaints to be sent back to WordFly. Abuse complaints are sent when a subscriber clicks on the spam button in their email. Most FBLs are IP-based which means that WordFly has already signed up for these. Yahoo is the only ISP that has a domain-based FBL.

Learn how to set up the Yahoo FBL in this article. Let us know if you need assistance with any part of this process by replying back to your WordFly Getting Started ticket or other open support ticket.


Before you set up the Yahoo FBL

Before starting this process, make sure you have completed these items:

  1. DKIM published for your sending domain
  2. Postmaster@ mailbox set up for your sending domain and ready to receive incoming emails
  3. Yahoo email account (either a personal account or company use account works). If you do not have a Yahoo email account, go to and select Create Account. Follow the instructions to create an account.

Note: If you are using Gmail for your company emails, Gmail removes direct access to the postmaster@ mailbox. Open a support ticket with Google and explain that you need to set up the Yahoo FBL using the instructions in this article. Google can help you with the verification code that is needed to finalize the FBL request.

  • The email from Yahoo will be coming from '' and IP You can try adding their from address to your contacts list or safe senders list; or, ask your IT team to safelist the sending IP.
    If you are not receiving the Yahoo FBL email you might try:
    (1) Confirm that your postmaster mailbox is actually receiving any outside emails at all. If you can't find this message you probably have a problem to fix before finishing the FBL.
    (2) Check to see if your mail server is rejecting the verification code email message because the from line used by Yahoo is too long. (This is mostly an issue on the PowerMTA platform.)
  • Open the email from Yahoo and retrieve the verification code.
  • To resend a verification email, you must fill out the form again.
