If you are not receiving emails to your domain mailbox, the problem is usually one of these:
- DNS (MX records) point to another mail server
- the mailbox does not exist or is disabled
- messages are filtered to Spam/Junk or forwarded elsewhere
- the mailbox is over quota (full)
This guide is written for GARMTECH email services and helps you isolate the cause.
1) Confirm the mailbox exists and you can log in
- Open GARMTECH.Email and try to sign in to the mailbox.
- If you use mailboxes created in Plesk (hosting mail), verify the mailbox exists in Plesk: Mail → select domain.
2) Check Spam/Junk and filters
- In GARMTECH.Email check Spam/Junk folder.
- Review rules/filters and forwarding settings (a rule can move mail away from Inbox).
- Temporarily disable forwarding to test.
3) Check mailbox storage (quota)
If a mailbox is full, many senders will receive a bounce like “Mailbox full” and mail will not be delivered.
- Delete unnecessary messages (especially large attachments) and empty Trash.
- If available in your plan, increase mailbox quota.
4) Verify MX records for your domain
MX records tell the world where to deliver email for your domain. If they point to another provider, GARMTECH mailboxes will not receive new mail.
- If you use GARMTECH nameservers (ns1.garmtech.com, ns2.garmtech.com, ns3.garmtech.com), check DNS in Plesk (Websites & Domains → DNS Settings).
- If you use external DNS (Cloudflare, registrar DNS), check MX records there.
Important: Your MX target must match your active GARMTECH email service. In most cases it should point to the server hostname shown in My.GARMTECH for your email/hosting service.
5) Allow time after DNS changes
If you just changed MX or nameservers, delivery may still go to the old provider until caches update. This depends on DNS TTL and can take from minutes up to 24–48 hours.
6) Test delivery
- Send a test email from an external mailbox (for example Gmail) to your domain mailbox.
- If possible, ask another sender to test too (some providers treat unknown senders differently).
7) If the sender gets an error (bounce)
Ask the sender to forward you the bounce/undelivered message. The bounce text usually shows the exact reason (wrong MX, mailbox missing, mailbox full, spam rejection, etc.).
