💡 What’s an MX Record?

An MX Record (Mail Exchange Record) is a DNS entry that tells the internet where to deliver email for a domain.

Think of it like a postal route:

“To deliver mail to info@firstday.ca, send it to the mail server at canada6.rebel.com.”

Without a valid MX record, email delivery will fail completely.

🧾 Example MX Setup for firstday.ca

If the domain firstday.ca is hosted on Plesk with Rebel email, the correct MX setup is:

Field	Value
Type	MX
Host/Name	@ (represents root domain)
Points to	canada6.rebel.com.
Priority	10
TTL	600 (or default)

✅ Notice the period (.) at the end of canada6.rebel.com. — it’s optional in many interfaces, but always treated as a full domain.

🧠 When Is the MX Record Relevant?

Situation	How MX Record Affects It
Email not sending or receiving	Likely MX is missing or wrong
Customer migrated to Gmail/Outlook	MX must be updated to point to their servers
Webmail works, but not Outlook/Gmail	MX might be fine — issue could be SMTP/IMAP settings
Email used to work, now doesn’t	MX might have changed (check DNS zone)

---

❌ Common Issues to Watch For

Problem	What’s Likely Happening	Fix
No MX record at all	Email has nowhere to go	Add correct MX pointing to canada6.rebel.com
Wrong MX server	May point to old host or incorrect provider	Update to canada6.rebel.com
Multiple MX entries with same priority	Rare; could confuse routing	Keep a single, clear MX unless intentionally load balanced
Using Gmail but still pointing to Rebel	Emails may not arrive in Gmail	Replace Rebel MX with Gmail’s records

✅ Agent Checklist

• 🔍 Check DNS zone in Plesk → DNS Settings
• ✅ One MX record: @ → canada6.rebel.com with priority 10
• 🧪 Use external tools to confirm: MXToolbox, DNSChecker
• 🗣 Ask customer:
  • “Where is your email hosted?”
  • “Are you using Webmail or Gmail/Outlook?”
• ⚠ Don’t add both Gmail + Rebel MX records at the same time — choose one

---
