Yes I would add some reverse lookups for vCenter Server nd all your hosts.

And then check them all using nslookup or whatever tools you use.

Some particularly strict email filters check the RDNS against the presented name in the SMTP HELO message.  If the two do not match, outgoing emails may be rejected.

So yes, RDNS should be configured and in particular, the RDNS lookup should match the FQDN presented in the email sender's HELO message.
