Step by step, following the numbers
- The sender’s server looks up your domain’s MX and sends the message to
mx.thailandhosting.com. - The message goes into a mailbox on your mail server. Mail is only accepted once your domain is verified.
- Read mail in Webmail or a mail app over IMAP (
imap.thailandhosting.com). Messages and folders match on every device. - Your mail app or your systems (a website form, a printer) send through
smtp.thailandhosting.comon port 465 or 587, with the mailbox’s username and password. - Mail goes out with a DKIM signature and counts toward the month’s sending quota. Mail to domains we host doesn’t count.
- The receiving server checks your domain’s SPF, DKIM and DMARC. When all three pass, the chance of landing in spam drops a lot.
If something’s wrong, which step to check
| Problem | Steps | What to check |
|---|---|---|
| No mail coming in | 1–2 | MX points to mx.thailandhosting.com with no old MX left, and the domain is verified (Set up DNS) |
| A mail app can’t sign in | 3–4 | The username is the full email address, and the port matches the encryption (Set up mail apps) |
| Mail stuck and not going out | 5 | The month’s sending quota is used up and extra sending is off (Plans) |
| Recipients get it, but in spam | 6 | SPF, DKIM and DMARC show as passing on the Domains & DNS tab |
Moving from another provider? Create all your mailboxes first, then switch the MX to ours and delete the old MX. While the DNS change spreads, some mail may still go to the old place.
