Managing DNS for ARUBA email

  1. I have as registrar where my domain is registered.
    I mapped changing the dns in aruba to the WordPress ones:
    Everything fine. The mapping was completed in approx. 5 hours.
    Of course the mail at aruba stop working.
    I asked to aruba how to change the DNS to maintain at the same time the wordpress dns and the mail working at aruba.
    They don't know how to help me.

    Can you help me in configuring DNS in WordPress for let the mail working in aruba?
    From aruba control paneI I only have this information:

    Mail Record Aruba

    Thank you

    The blog I need help with is

  2. Howdy,

    From checking the domain's current MX record (where DNS tells e-mail servers to use for mail), the MX record should be

    From what you pasted below, those look to be A records (pointing a specific subdomain to an IP address(es)).

    Is that correct from your understanding?

    If so, your Custom DNS ( at ) should be set to

    MX 10
    A mx
    A mx
    A mx
    A mx
    A mx
    A mx
    A mx
    A mx

    in order to receive mail.

    For your e-mail clients and your web client, I would think that the rest of the entries would be added as A records in addition to the above. Thus:

    A pop3
    A pop3
    A pop3
    A pop3
    A pop3
    A pop3
    A pop3
    A pop3
    A mail
    A mail
    A mail
    A mail
    A mail
    A mail
    A mail
    A mail
    A smtp
    A smtp
    A smtp
    A smtp
    A webmail
    A webmail

    I'm happy to add these, with your permission, or you could add them as well.

    Since your e-mail provider didn't provide confirmation, there's the possibility that we may be missing something. However, from examining your current DNS, I feel confident in this solution.

  3. Thank you very much for your kind reply.
    For the moment, in order to re-activate e-mail addresses to the people working at (!), I have restored default DNS at The e-mails now are back, but (of course) the web disappeared. I choose the minor damage, let's say.
    I will try your solution re-mapping during the week-end.

    I will take you informed!



  4. Please do let me know how it works out. I typically am not online during the weekend, but will check in over the weekend in case you need anything. Worst case, I'll field anything you need first thing Monday morning (in the States).


  5. OK! Thank you again.

  6. Dear kraftbj, from Aruba they suggest a possible different solution.
    Can you please let me have the ip address of ?
    I noticed that you at WordPress gave this info for similar solutions (see for example
    Thanks again.

  7. We don't recommend assigning A records to the IPs on Each site is fully cloud-based and distributed on a number of servers with a load balancer. The six IPs that would need to be assigned can and will change (as we deploy additional servers, add datacenters, etc), which could result is degraded performance or outright failure.

    I'll send you an e-mail to the address on the account with additional information (as I wouldn't want someone to find old IP addresses, like in the post you linked to, and use the outdated information).

  8. Dear Brandon, good job!
    I followed your recommendation and now our domain is successfully remapped in wordpress and at the same time the e-mail managed by the registrar ARUBA are ok.

    Last problem:
    we have a third level at that is on an external machine at that now is no more working. I added the line in the DNS:
    But it doesn't work. Do you have a solution for this too?

  9. Hi Gherardo,

    Sure thing! I made a small tweak, since the line should be A ojs—as it was, it actually created an A record for

    It should start working as soon as the DNS caches cycle.

    Please let me know if you have any questions or need anything else!

  10. Brandon I'm very, very sorry I have to disturb you again.
    Everything was fine.
    I was trying to verify with the tool for Google App. After I pressed the button "Generate DNS records" WordPress generated the new records but also deleted all the previous DNS records!
    So I erased all the DNS records and then wrote again the previous DNS records. I validated and then saved.

    Now I have this new problem with e-mails
    - we are able to send from
    - we are able to receive mails sent to BUT the person who send an email to receive this message back of "Mail Delivery Subsystem":

    Delivery to the following recipient failed permanently:

    [email redacted]

    Technical details of permanent failure:
    Google tried to deliver your message, but it was rejected by the server for the recipient domain by [2607:f8b0:4002:c02::1b].

    The error that the other server returned was:
    550-5.1.1 The email account that you tried to reach does not exist. Please try
    550-5.1.1 double-checking the recipient's email address for typos or
    550-5.1.1 unnecessary spaces. Learn more at

  11. Brandon it seems now everything is ok. Maybe just a matter of propagation?

    Thanks a lot for your help!



  12. What i looks like is when you sent the e-mail, it went through during the time when the Google MX records were set by the Google Apps tool since the failure is coming from Google Apps' server.

    Likely just a bit of a hiccup with changing over the DNS settings, but I'd imagine everything should be good going forward, assuming nothing changes on the setup!

    Please do let me know if there's anything else I can do for you!

  13. Great support!

    Thank you
