Planisys

Planisys is a brand that provides various products and services to enhance email security and prevent unauthorized use of domains. One of their key offerings is DMARC, which stands for Domain-based Message Authentication Reporting and Conformance. DMARC helps to identify legitimate emails and instructs receiving email servers on how to handle emails that fail authentication checks.

Implementing DMARC offers multiple benefits. For the emails you send, receiving email systems that respect DMARC will quickly identify them as legitimate, improving deliverability and lowering the risk of identity theft. For the emails you receive, using Planisys' AVAS SEG ensures that you receive emails from authenticated sources in your inbox, while suspicious emails are either placed in the spam folder or directly quarantined.

To enable a third party like Planisys to send legitimate emails on your behalf, they enforce the use of DMARC by creating a sub-domain related to their bounce processor and SPF policies. This ensures that the Return-Path and the From headers are aligned with DMARC. DMARC works in conjunction with other technologies like SPF and DKIM.

SPF verifies the authorized IP addresses to send email on behalf of a domain, while DKIM adds a digital signature to ensure the integrity of the email content. To check if your SPF, DKIM, and DMARC settings are correct, Planisys offers a free tool for verification. Publishing a DNS record called _dmarc.

domain. com allows others to become aware of your domain policies. This record specifies DMARC policies, including how to handle unauthorized emails, where to send reports, and what actions to take.

Planisys also provides information on SPF and DKIM settings, offering guidance on configuring them correctly for optimal email authentication. It's important to note that not all email systems comply with DMARC policies. However, AVAS SEG from Planisys can be configured to honor DMARC, offering enhanced protection against unauthorized emails from other domains
