Question blueyonder.co.uk email rejection 550 / Hostname Generic and needs changing

[LeighWhiting]

Hi All

Blueyonder are rejecting emails from our Server and the reason is below

The DNS pointer record for this IP (xxxxxx.vps-10.com.) appears to match a generic or default pattern that is often associated with spam. Cloudmark will not continue to remediate such IP addresses.

Please could you update the rDNS on this IP to be something more specific to the sender and/or your organisation rather than the generic pattern that the provider has assigned by default. You may need to contact your provider in order to accomplish this rDNS change.

For instance mail.example.com would be considered far less generic than 208-83-136-1.sfo.example.com or hosted-by.example.com

is it just a case of changing our Full Hostname in Tools & Settings -> Server Settings ? if yes, what other bits need changing on will the server sort it automatically ?

Yes, you'll need to change the hostname of your sever to something other than xxxxxx.vps-10.com. After doing so you'll also need to change the reverse-DNS record (rDNS) for the IP address of your server. Contact your provider and ask them how change the rDNS record to point to your newly set hostname.
