PowerDMARC’s Email Authentication and Information Security Knowledge Base

Let’s countdown the list of solutions, protocols and practices that you can include in your security suite to stop your emails from landing into the junk folder.

Permanently get rid of the "No SPF record found" message with easy SPF configuration for your domain.

While using SPF, the risk of generating too many DNS lookups can make you exceed the 10 DNS lookup limit. Mitigate this with PowerSPF.

SPF flattening is an industry-favourite method to counter exceeding the 10 DNS lookup limit, but you should avoid it. Here’s why.

MTA-STS and TLS-RPT can help domain owners ensure encrypted flow of messages and effective reporting of email delivery issues, respectively.

SPF is not perfect and comes with a set of limitations which need to be optimized and modified to suit your needs.

Email authentication protocols like DMARC can help you minimize BEC effectively, while staying within your budget!

Fix the “No DMARC record found” prompt by adding DMARC record for your domain with PowerDMARC.

Email forwarding can drastically impact your SPF and DKIM authentication results and lead to DMARC failure.

TLS downgrade attacks can enable attackers to convert a secure connection into an insecure one and access and tamper with your messages. Learn about how MTA-STS mitigates TLS downgrade attacks and makes mail server connection secure.
