I took over the work from another web developer and try to figure out, how he migrated an email account from old Webhost + Domain (domainA, hostA) to a new Webhost + Domain (domainB, hostB).

This is the configuration:



domainA is added as addon domain on hostB. When I send an email to [email protected] the email only appears on web server B (I can see it in File Manager) not on web server A.

HostingA is cancelled the next week. (including the domainA). It seems, that I cannot manage the domainA in the admin panel anymore, but I think he did it before the cancellation.

I tried to find out how this "redirecting" of the emails works, by searching some redirecting settings on admin panel + cpanel on hostA but I just can't find it.

So, how did he do that?

I'd be happy for any explanations. I want to unterstand this because I want to renew the registration of domainA and wants to be sure, that the email address [email protected] will still work after accomplished cancellation of hostingA next week.

    What are your DNS records for domainA and domainB? Especially relevant or the MX records which are for email. Commented Mar 1, 2022 at 14:23

  • @StephenOstermiller Thank you for your comment! I checked the MX records on domainA but it is pointing to hostA. But I found out, that the previous web developer already transferred domainA to another registrar. I will check the MX records there when I got the log in credential of the new registrar. I think, I will find my answers there. :) Commented Mar 2, 2022 at 0:39

    @Steve thank you so much for this link! That confirmed my guess, that the MX record is set to hostB. Commented Mar 2, 2022 at 0:40

I checked the MX records in the zone editor of where I thought domainA's DNS was hosted and found it was pointing to hostA.

But I discovered that domainA's DNS had been moved to another host.

When I checked the MX records of domainA at intodns.com I discovered that the active DNS is hosted at hostB. So I was originally looking in the wrong place.
