Looks like i have a non-resolvable HELO name. You will see below&&&
NOQUEUE: reject: RCPT from 22.214.171.124.ptr.us.xo.net[126.96.36.199]: 450 4.7.1 <STS-EXCH.sts.local>: Helo command rejected: Host not found; from=<firstname.lastname@example.org> to=<SHderring@acddstsoft.com> proto=ESMTP helo=<STS-EXCH.sts.local>
I know that STS-EXCH.sts.local is not a valid name.
So can someone point me in the right direction as to where i can change it to sts-exch.strategictelecom.com , The DC is sts.local and the exchange server is a member of that domain.
