Það hefur borið á því að póstur frá schoolarchive.net hafi flokkast sem ruslpóstur (SPAM/Junk mail). Því er búið er að virkja og stilla eftirfarandi fyrir lénið til að fyrirbyggja þessa flokkun á póstinum:
- Sender Policy Framework (SPF) is an email authentication method designed to detect forging sender addresses during the delivery of the email.
- DKIM allows the receiver to check that an email claimed to have come from a specific domain was indeed authorized by the owner of that domain.
- DMARC, which stands for “Domain-based Message Authentication, Reporting & Conformance”, is an email authentication, policy, and reporting protocol. It builds on the widely deployed SPF and DKIM protocols, adding linkage to the author (“From:”) domain name, published policies for recipient handling of authentication failures, and reporting from receivers to senders, to improve and monitor protection of the domain from fraudulent email.
