  Hello,

  For the last two weeks, the 2FA emails for my main WordPress site and all child sites have stopped arriving in my inbox. I am using a security plugin for 2FA, and they confirmed that the issue is not on their end, as they use wp_mail() to send emails. What I Have Verified So Far:

  • The email address (email visible only to moderators and staff) is receiving all other emails except for the 2FA emails.
  • I installed WP Mail Logging and confirmed that the 2FA emails are being generated and sent by WordPress. However, they are not reaching my actual mailbox.
  • My security plugin support team suggested that the issue might be server-related rather than their plugin.

  Since this raises security concerns, I’d really appreciate any guidance on troubleshooting this issue. Is there a known issue with wp_mail() in certain server configurations? Could this be related to spam filtering, email authentication settings (SPF, DKIM, DMARC), or something else on the hosting side?

  Looking forward to any insights you can provide.

  Thanks in advance!
