We have DNS records of Sophos on our hosting. It was set up by company that installed Sophos Central at our company. Whenever IP adresses of Sophos change, e-mails stop coming until I edit DNS records and put in new correct IP adresses. Is this the right way? Is it the way it should be?
Dns records are for adresses mx-01-eu-central-1.prod.hydra.sophos.com and mx-02...
Jan Novak the MX addresses should not be an A record but an MX record. So this needs to be changed.
Here is an example, it should not have the "A" but an "MX":
We also have MX records. But without A records e-mail doesnt work - when Sophos change those two IP addresses (it happened twice in half year already) e-mails stop coming until I correct those two IPs in A records.
normally, you do not need to define any sophos.com on your own DNS-Server, as long as this (internal) DNS has a (public) DNS it can forward the requests whcih it is not able ro resolve from its own zones.

You are both correct. The problem was missing dots at the and of address of MX records (after "com"):
After I put them there, hosting let me delete A records and e-mails arriving.
