Why It Matters for Sender Reputation
A blacklist queried via DNS. Mail servers check incoming connections against DNSBLs to identify known spam sources. Understanding this concept is essential for maintaining good email deliverability and protecting your domain's sender reputation.
How It Works
Email security threats can damage your sender reputation and compromise your sending infrastructure. Understanding these threats helps you protect your domain and maintain deliverability.
Practical Example
When configuring your email sending infrastructure, paying attention to dnsbl (dns-based blackhole list) is critical. A misconfiguration or oversight in this area can lead to decreased deliverability, increased spam filtering, or even blacklisting.
