DMARC (Domain-based Message Authentication, Reporting and Conformance)¶
DMARC is a technical specification, created by a group of organizations to help reduce the potential for email-based abuse, such as spam, email spoofing and phishing e-mails, by solving some long-standing operational, deployment, and reporting issues related to email authentication protocols. DMARC standardizes how email receivers perform email authentication using the well-known – Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) mechanisms.
- DMARC is a technical specification
- DMARC standardize receivers email authentication using SPF and DKIM
- DMARC helps to indicate email protection (enable SPF and DKIM)
- DMARC will move mails which fails SPF and DKIM to junk or reject
- DMARC helps the users to protect from fradulent and harmful activities.
Enable or disable DMARC report
There are two ways for doing that:
- Via the MailCleaner administration interface: Configuration > SMTP > Enable reporting to DMARC domains
- Restart the Incoming MTA services at Monitoring > Status
Purging reports:
For purging DMARC reports you can delete reports:
cd /tmp/dmarc_reports && find . -mtime +15 -delete
Or simply compress it:
cd /tmp/dmarc_reports && find . -mtime +15 -exec gzip {} +
