How Do I Modify My Domain MX Records?

Short answer: If your domain is registered with Infosaic, change MX records yourself at mydomain.infosaic.com — sign in with your domain name and hosting password. If your domain is registered elsewhere and merely pointed at our DNS, open a support ticket with the MX details and we will enter them for you.

Applies to: Infosaic web hosting · domains using Infosaic DNS · mail hosted with Microsoft Exchange, Google Workspace or another third party

MX records decide where email for your domain is delivered. Everything else about the domain can be pointing at us while mail goes somewhere else entirely — that is normal, and it is what MX records are for.

You will need to change them if you move mail to or from a third-party provider, if you run an in-house Exchange server, or if you have just pointed a domain at us and mail needs to keep going where it was.

Which route you use depends on whether we are your registrar or only your DNS host.


If the domain is registered with Infosaic

If we are the acting registrar for your domain, you can make DNS changes yourself — including MX records — from the domain management control panel.

  1. Go to mydomain.infosaic.com.
  2. Sign in with your domain name and your hosting password.
  3. Open the DNS or MX section.
  4. Edit the records and save.

The same panel handles A records, CNAMEs and the WHOIS contact details, so any other domain administration can be done in the same visit.


If the domain is only pointed at Infosaic DNS

If the domain is registered somewhere else and simply points at our name servers, the records live on our DNS servers and are not exposed in a self-service panel.

Open a support ticket through your hosting control panel at controlpanel.infosaic.com and give us the MX information. We can enter custom MX records for an internal Exchange server, for a third party such as Google Mail, or for any other provider.

Include the full hostname and the priority for each record, exactly as your mail provider supplies them. That is usually enough for us to make the change on the first pass.

Send the records exactly as your provider gives them. A screenshot of their setup page is ideal. MX hostnames are long and easy to mistype, and a single wrong character silently stops mail rather than producing an error.


What to expect after the change

Changes normally take effect within minutes, not hours. During the changeover, some mail may still be delivered to the old server, so leave the old mailbox reachable for a day or two rather than closing it immediately.

If mail stops arriving completely, check these in order:

  • The MX hostname is correct — compare it character by character with what your provider specified.
  • The priority values are right. Lower numbers are tried first; several records with the same priority share the load.
  • There is no leftover old MX record still pointing at the previous server.
  • Any SPF record has been updated to authorise the new sender, or outgoing mail may be treated as spam.

If it still is not right, open a ticket with the domain name and where mail should be going. We can see what your domain is currently publishing, which normally identifies the problem straight away.


Questions and answers

Where do I change MX records for a domain registered with Infosaic?

At mydomain.infosaic.com. Sign in with your domain name and hosting password.

My domain is registered elsewhere but points at Infosaic DNS. How do I change the MX records?

Open a support ticket from your hosting control panel with the MX details and we will enter them.

Can Infosaic set up MX records for Google Workspace or Microsoft Exchange?

Yes. Custom MX records can be entered for an internal Exchange server, Google Mail or any other provider.

What information do you need from me?

The full MX hostname and priority for each record, exactly as your mail provider supplies them.

How long does an MX change take to work?

Usually a few minutes. Some mail may still reach the old server briefly, so keep the old mailbox available for a day or two.

Why has my mail stopped arriving after changing MX records?

Most often a mistyped hostname, a wrong priority, or an old MX record left in place alongside the new one.

Do I need to change my SPF record too?

If mail will be sent from the new provider, yes. Otherwise outgoing messages may be marked as spam.

Does pointing my domain at Infosaic move my email automatically?

It moves mail delivery to us unless MX records are set to send it elsewhere. Decide where mail should go before pointing the domain.
