This and one other PTR record point to domain names which are CNAMEs.
Per RFC-1035, PTR records should point to canonical names.

Replace `xis.xtenit.com' with 'xtenit.com' and `www.ultraoptions.com'
with `ultraoptions.com'. There's a similar problem in the forward-mapping

Replace `mail.selectacast.net' with `p1.selectacast.net' to fix this.
