Discover the rich features in PowerMTA that help you adopt and adapt to changing email authentication standards including support for DKIM and SPF and setup for DMARC. To use our automated testing tool, send a sample of a marketing email or newsletter to receive immediate summary results. Senders can choose where the results should be sent:
- If you wish to receive the results at the address in the “mail_from,” the sample message should be sent to firstname.lastname@example.org.
- If you wish to receive the results at the address in the “from” header, the sample message should be sent to email@example.com.
- If you wish to receive the results at a different address from one of the addresses above, the address need to be added to the check-auth address. For example, to send the results to:
firstname.lastname@example.org the sample message should be sent to email@example.com.
A reply email will be sent back to you with an analysis of the message’s authentication status. The report will perform the following checks: SPF, SenderID, DomainKeys, DKIM and Spamassassin.
