Unable to receive emails within domain after changing public IP RRS feed

  • Question

  • Hello Team,

    I am using Exchange Server 2010, Recently we have switched over to another ISP, so the public IP has been changed.

    We have made the changes at the firewall level as well as we have updated the following changes. 

    1. MX record to reflect the new public IP address

    2. SPF record you have to the new IP address

    Issue:- We are able to receive mail out of domain but from within domain we are unable to receive any mail.

    We made the changes at child domain (.in) and parent domain is (.com) other child domain (.tr,.fr,.ts)

    (.in) domain is unable to send or receive  from any child domain though mail exchange between other domain is successful.

  • Hi Kapoor,

    Thank you for your question.

    Did you send email in domain?

    First of all, we could check all configuration on firewall, route(NAT),Edge server and so on.

    Then we could rebuild Edge subscription to check if the issue persist.

    We could use the following link to check connectivity.

    If there are any questions regarding this issue, please be free to let me know.

    Best Regard,

    Jim

  • Maybe the other servers have your server name in a hosts file.  It could be just about anything name-related.

  • Can you check for any send connectors configuration that needs to be updated?
