MX Records Explained: How Incoming Business Email Finds Your Inbox
What MX records do, what priority means, common mistakes, and exactly what to publish when connecting your domain to OquMail.
When someone sends to you@yourcompany.com, their provider looks up MX (Mail Exchanger) records for yourcompany.com. Those records name the server allowed to receive mail and in what order to try backups.
What you publish for OquMail
OquMail gives you a hostname (mail.oqumail.com) and a priority number. Add one MX record pointing @ (root) to that host. Remove old MX records from previous providers or mail will split across two systems.
Common MX mistakes
- Leaving Google or Zoho MX records alongside new ones
- Using a CNAME on the root domain (breaks MX at many DNS hosts)
- Typo in the mail host — verification catches this before you go live
- Forgetting that DNS propagation can take up to 48 hours (often minutes)
