Hi Ukender,

 

So this isn't a Campaign issue but a deliverability one.  For deliverability responses like this your best option is to simply do a web search (Google) the error.  Searching the error you listed provides numerous results.  Most point to a missing PTR record but there are slight variations based on the domain you are mailing to.

 

Regards,

Craig
