Why It Matters for Sender Reputation
A validation where a PTR record resolves to a hostname, and that hostname resolves back to the original IP. Understanding this concept is essential for maintaining good email deliverability and protecting your domain's sender reputation.
How It Works
Your email infrastructure configuration directly impacts how mailbox providers evaluate your domain. Proper setup of DNS records, mail servers, and encryption ensures reliable email delivery.
Practical Example
When configuring your email sending infrastructure, paying attention to forward-confirmed reverse dns (fcrdns) is critical. A misconfiguration or oversight in this area can lead to decreased deliverability, increased spam filtering, or even blacklisting.
