Hi, I'm trying to get an e-mail account working and I have the following enquiry. When you change the DNS for a domain, does this invalidate the previous MX Records? I can add MX Record in the new control panel but they don't seem to work, perhaps I should change it from the registrar control panel?
The MX record needs to be set with whoever is handling the DNS for your domain. If your domain is using your registrar's nameservers, you'd use the registrar's control panel to set MX records. If you're using your host's nameservers, you'd use the hosting control panel to set MX records.
What exactly isn't working with what you're doing at present?
All right, thanks. I'm using a free CPanel for testing and it says that in order to receive e-mail throught a client, I must point the MX record of my domain to their mx.cpanlhost.domain.com. I did but the client does not receive the e-mails.
How have you pointed the domain to the free cPanel account? (Have you changed the nameservers at the registrar, or are you using the registrar's nameservers, and set up an A record to the cPanel server?)
Right, so you changed the A record at the registrar's DNS server?
In that case, you set the MX records at the registrar too? Could you check that there's only one record there, and that it exactly matches the entry the host gave you. It should have priority of 1.
If that's all exactly right, you'd need to ask the host to look at it. If you wanted to post the domain here, someone may be able to see what's wrong, but equally the problem may not be visible to someone without access to your account.
No, A record was not changed at the registrar's DNS server. I did not change anything except DNS at the registrar. I set the MX record directly in the free cPanel account: mx.mydomain.edu > mx.freecpanel.edu with priority 10.
I think the problem is that when I add this account to Thunderbird, the SMTP is incorrect (because they don't provide it) so the account cannot be configured. Not even for receiving.
As you have changed the DNS for your domain, therefore no need to change the MX record, you can contact your hosting provider and consult the mail issue with them, so that hosting provider will check the DNS record for your domain and update you, if anything wrong with the DNS records.
