Email Delivery Issues

If you're not receiving emails, follow these steps to diagnose the issue.

Step 1 — Check MX Records

Your domain's MX records must point to our mail servers.

dig MX yourdomain.com +short

Expected:

10 mail.techtemple.au

Step 2 — Check Spam/Junk Folder

Many email clients automatically filter emails into Spam. Check your Junk folder and mark legitimate emails as "Not Spam".

Step 3 — Check Email Account Quota

If your mailbox is full, new emails will be rejected.

  1. Log in to cPanel → Email Accounts
  2. Check the storage usage for each account
  3. Delete old emails or increase the quota

Step 4 — Verify the Sender's Email

Ask the sender to check their bounce notifications. A bounce message will tell you exactly why delivery failed.
