Can't mail to hpeprint.com from Ionos

[RussBoy]

Hi, I am trying to print using hpeprint.com.  This works from gmail but not from my Ionos email account.  The error I receive is:

550 Invalid DNS MX or A/AAAA resource record:

The sender domain of the email server you are using is not configured RFC-compliant in the domain name service (DNS). This may be due to the following causes:

• Neither an A nor an MX record is configured in the DNS for the sender domain.
• The MX record refers to a domain name that cannot be resolved.
• The MX record refers directly to an IP address.
• The MX server does not have a valid A-record but only a CNAME record

Looking into the DNS record for hpeprint.com (using intodns.com), I see the following:

MX A request returns CNAME WARNING: MX records points to a CNAME. CNAMEs are not allowed in MX records, according to RFC974, RFC1034 3.6.2, RFC1912 2.4, and RFC2181 10.3. The problem MX record(s) are:
emailinbound-ext-prod.inc.hp.com points to ['eprint-emailinbound.glbinc.hp.com']
This can cause problems

 Which seems to explain the issue.  Is there any way of getting this fixed?

Regards.
