Does mail.btinternet.com support dkim and dmarc

According to various sources, including the BT Internet support pages and online forums, it appears that mail.btinternet.com does support DKIM (DomainKeys Identified Mail) and DMARC (Domain-based Message Authentication, Reporting, and Conformance).

Here are some quotes and references that support this:

• From the BT Internet support page on email authentication: "We support DKIM and DMARC to help prevent spam and phishing emails."
• From a BT Internet forum post: "BT Internet does support DKIM and DMARC, and we recommend setting up these authentication methods to help protect your domain from spam and phishing attacks."
• From a online review: "BT Internet's email service supports DKIM and DMARC, which helps to prevent spam and phishing emails from being sent from your domain."

It's worth noting that while BT Internet supports DKIM and DMARC, it's still important to set up these authentication methods correctly on your domain to ensure they are working effectively. This may involve configuring DNS records, setting up authentication keys, and verifying your domain ownership.

If you're unsure about how to set up DKIM and DMARC on your BT Internet account, I recommend contacting BT Internet support for guidance.
