The spam filter and the MX, SPF, DKIM and DMARC records

Email for your domains goes through our filter, which stops spam and viruses and signs what you send. Which records it uses and what to do if it stopped a good email.

Email for your hosting's domains goes through Fodenflow's mail filter: incoming mail is checked before it reaches your mailboxes (to stop spam and viruses), and what you send goes out signed with DKIM so other servers trust it.

The records it uses (in your domain's DNS zone)

  • MX: points to pmg.yourdomain, the filter's entry point.
  • SPF (TXT on @): authorizes our servers to send for your domain.
  • DKIM (TXT on pmg._domainkey): your emails' signature.
  • DMARC (TXT on _dmarc): tells other servers what to do with email that fails SPF and DKIM.

If your domain uses our name servers, we add these records when you add it to your hosting. If your email is received by another service (for example Google Workspace), we don't touch its MX records.

If the filter stopped a legitimate email

  1. Ask the sender for the error message they got back, if any.
  2. Open a request with the topic Email, the mailbox, the sender and the approximate date and time.
  3. We look it up in the filter and, if appropriate, release it and adjust the rule.

When you're signed in, the AI Assistant checks your domain's email (MX, SPF, DMARC and whether it goes through the filter) and, if something is missing, offers to re-apply the setup.

There must be only one SPF record per domain. If you add another service that sends email for your domain, add it to the existing SPF instead of creating a new one.
