How does one go about changing the HELO?  Does it automatically use the
"official hostname" or can change that in Imail admin or the registry
somewhere... I have done a quick search but dont seem to find this
anywhere...

> 571 - MAIL REFUSED - Reverse DNS failed - IP address mismatch.

The implication of this error is that your outgoing IP, 63.147.233.20, fails
the  common  "loopback"  test  that checks to see if there is a seamless
IP-to-PTR-to-A-to-IP  mapping. However, 63.147.233.20 indeed loops  back
correctly  to  mail.sbsnet.com and back to 63.147.233.20, meaning  that  the
remote end is having DNS issues (or is misreporting the  reason  for  the
rejection).

Note  that  your  are  HELOing as sbsnet.com, which is NOT in fact the
canonical  name  for  the  mail server (its A record points to another
IP):  this  is  not  a  good  practice,  and also possible grounds for
rejection.
