If mail to your domain is not arriving, work through these checks in order. Most problems are in the first three.
1. Check Junk / Spam. 2. Check your domain's MX records point to the right mail service. 3. Check filters and forwarders. 4. Ask the sender for the bounce message. Then open a ticket with what you found.
1. Check Junk or Spam
On Business Email, likely spam is filed to Junk Mail and never deleted, so look there first. On DirectAdmin hosting, check the spam folder and your SpamAssassin settings. See How to Configure Spam Filters.
2. Check your MX records
MX records tell the internet where to deliver mail for your domain. If they point to the wrong place, mail goes somewhere else or nowhere.
- Business Email: your MX record must match what is shown for your domain in your Business Email service.
- DirectAdmin hosting: MX must point to your hosting server.
- Container Hosting has no mailboxes, so MX should point to your email provider, for example Business Email.
Check with an online tool such as MXToolbox, or with dig MX yourdomain.com. After a change, allow time for DNS to update. See Setting Up MX Records for Email.
3. Check filters and forwarders
- Business Email: check your Mail filters and rules in webmail (
https://mail.stardomain.com) for a rule that moves or deletes the messages. Also check the mailbox's forwarding and aliases in your Business Email service. Business Email has no catch-all, so mail to an address that is neither a mailbox nor an alias is not delivered. - DirectAdmin hosting: check E-Mail Manager › Forwarders, Catch-All E-mail and your email filters.
4. Check the mailbox itself
- Make sure the address exists and is spelled the way senders use it.
- DirectAdmin hosting: a full mailbox refuses new mail. Check its quota in E-Mail Manager, and delete or archive old mail.
- Make sure the service is active and not suspended for an unpaid invoice.
5. Ask the sender for the bounce
If the sender got an error message back, ask them to send you the whole message. It usually says exactly what went wrong, for example "mailbox not found" or "domain not found".
6. Test from another address
Send a test from a different provider, such as Gmail. If that arrives, the problem is on the original sender's side, such as their server or their blocklists.
Still not arriving?
Open a ticket with: the receiving address, a sender address, the time of a missing message, and any bounce text.
Where does Business Email put spam?
In the Junk Mail folder. Nothing is bounced or silently deleted.
I moved my site to Container Hosting and email stopped. Why?
Container Hosting has no mailboxes. Point your MX records to an email service, such as Business Email, and set up your mailboxes there.
