We are getting ready to roll out improved DMARC settings on the elmah.io domain. For anyone not an expert on DMARC and email delivery, DMARC stands for Domain-based Message Authentication, Reporting, and Conformance. It is an email authentication protocol designed to give email domain owners the ability to protect their domain from unauthorized use, commonly known as email spoofing. We are already using DMARC but want even more restrictive security settings going forward.
Everything should continue to work as previously. But if you want to ensure that emails sent from the elmah.io domain reach your inbox, consider making changes as described here: How to avoid emails getting classified as spam.
