The Rule of MX Records
MX (Mail Exchange) records dictate where incoming mail is delivered.- If your apex domain (
yourcompany.com) points to Google Workspace (aspmx.l.google.com), do not modify your root MX records. - Mailofly only uses MX records for custom MAIL FROM return-path bounce handling or inbound routing on subdomains.
Recommended Solution: Use a Subdomain
To ensure zero risk to your team’s day-to-day corporate email:- Verify a dedicated subdomain such as:
mail.yourcompany.comupdates.yourcompany.comnotifications.yourcompany.com
- Add the DKIM, SPF, and MX records exclusively on that subdomain.
- Your corporate Gmail/Outlook inboxes on
yourcompany.comwill continue functioning without interruption.
