Yup, because what those servers are doing is flat-out not allowed by any
SMTP-related standard. The greeting name _MUST_ be the principal
hostname for the client. The whole idea is to clearly and uniquely
identify the client _host_, not it's sub-domain. This has been a
fundamental absolute requirement of SMTP for only about 20 years now.
